The present invention relates to a drivetrain package.

BACKGROUND INFORMATION

A model series of drivetrain packages and a method for producing drivetrain packages is German Published Patent Application No. 10 2008 058 521.

German Published Patent Appication No. 33 07 923 illustrates a base plate for machine units.

German Published Patent Application No. 10 2006 007 637 shows a cross member and a modular assembly system for a combined transport and setup system of a motor as well as a method for transporting and setting up a motor utilizing the cross member and modular assembly system.

SUMMARY

Example embodiments of the present invention provide a drivetrain package that may better protect the environment.

According to an example embodiment of the present invention, the drivetrain package includes a motor having a rotor shaft, a gear unit and a carrier structure.

The carrier structure has a carrier part, which includes a gear unit support section and a motor support part, the carrier part and the gear unit support section being provided in one piece.

The motor is mounted on the carrier structure with the aid of the motor support part, the motor support part in particular being disposed between the motor and the carrier part.

The gear unit is supported on the gear unit support section and connected to the carrier structure with the aid of the gear unit support section.

The carrier part includes a sheet-metal part.

The motor support part includes a sheet-metal part.

The carrier part extends farther in the direction of the rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis.

The motor support part extends farther in a transverse direction to the rotor shaft axis than in the direction of the rotor shaft axis.

This is considered advantageous insofar as the carrier structure made from sheet metal parts is able to be produced in a compact and uncomplicated manner. The torsional stiffness, torsion resistance, and the vibration strength of the carrier structure are improved by the motor support part disposed transversely to the direction of the rotor shaft axis. The resonant frequency of the carrier structure may lie outside the usual motor excitation frequency.

Sheet metal parts for the production of the carrier structure can be stocked in a space-saving manner and may be cut to the specific combination of motor and gear unit in a single working step. In particular the height of the rotor shaft of the motor and the input shaft of the gear unit are adaptable to each other in that the carrier part has different heights for the motor support part and the gear unit support section.

The motor support part and the carrier part may be uncomplicated in their production and can be produced with high precision in the form of punched parts or punched and bent parts. Time-consuming postprocessing of the carrier structure such as by grinding is therefore not necessary.

The cutting pattern for the components of the carrier part may easily be transferrable to different sizes of carrier parts or to different sheet metal materials. This provides high process reliability because the cutting pattern is unambiguously transferrable.

All parts of the carrier structure may be produced from the same sheet metal. A drivetrain package for an application under extreme external conditions that require a special material, in particular a steel alloy, may therefore be produced entirely from just such a material.

In addition, it is considered advantageous that the gear unit support section is able to be produced in a single production step with the carrier part. The torsional stiffness and the vibration strength of the carrier structure are further improved by the angularly arranged gear unit support section.

The carrier structure may include a base part, and the carrier structure may be supported with the aid of the base part, in particular on a foundation, especially a floor, and the motor support part and the base part may be arranged in a similar and, in particular, an identical manner. This has the advantage that the carrier structure is able to be placed on the foundation with the aid of the base part without the risk of tilting.

Since the motor support parts are reusable as base parts, a modular system with a reduced number of parts may be realized. The motor support parts and the base parts may be stocked in an economical manner, which is better for the environment.

The base part may extend farther in a transverse direction to the rotor shaft axis than it does in the direction of the rotor shaft axis. This is considered advantageous insofar as the torsional stiffness and vibration strength of the carrier structure are further improved with the aid of the base part.

The motor support part and the base part may have in each case a first recess and a second recess, and the motor may be connectable to the carrier structure with the aid of a fastening element guided through the first recess. The first recess in particular is arranged in the form of an elongated hole that extends farther in the direction of the rotor shaft axis than it does in a transverse direction to the direction of the rotor shaft axis. The carrier structure is able to be mounted on a foundation, in particular a floor, with the aid of a fastening element that is guided through the second recess. This is considered advantageous insofar as the first recess makes it possible to vary the axial clearance between the motor and the clutch and to adjust the clutch play.

The recesses may be produced in a single working step with the motor support part and/or the base part, in the form of a punched part. This makes it possible to reduce the production outlay and to better protect the environment.

The carrier part and/or the motor support part and/or the base part may be produced as bent parts, in particular as punched and bent parts, especially as sheet metal corner plates. This is considered advantageous because bent parts have better stiffness, in particular torsional stiffness, than planar sheet metal parts. The sheet metal parts may be thinner and material and weight may be saved, which benefits the environment.

The carrier part may have two subsections that are disposed at a non-vanishing angle relative to each other, this angle in particular being between 90° and 180°, in particular between 135° and 180°, and in particular between 150° and 170°. Situated between these subsections is an edge section that extends completely through the carrier part in the direction of the rotor shaft axis. This has the advantage of further improving the torsional stiffness of the carrier structure. The carrier part may have a thinner design, which is better for the environment.

The motor support part and/or the base part may be connected to the carrier part in a form-locking manner and by an intermaterial connection, in particular by welding. This has the advantage that weld seams between the motor support part or the base part and the carrier part may be smaller than in the case of an exclusively intermaterial connection. Material is therefore able to be saved and the carrier structure may be lighter.

The carrier part may have at least one positioning slot for the connection to the motor support part or the base part. This is considered advantageous insofar as it allows for an uncomplicated positioning of the motor support part or the base part on the carrier part. Manufacturing faults are avoidable.

The positioning slot may be produced in a single production step with the carrier part, in particular by cutting or punching.

The carrier may have a carrier section, which particularly extends from the motor to the gear unit; the gear unit support section is situated at a non-vanishing angle to the carrier section, the gear unit support section in particular being situated at a right angle to the carrier section. This has the advantage of allowing the gear unit support section to be produced in a single production step with the carrier part. The torsional stiffness and the vibration strength of the carrier structure are further improved by the angularly arranged gear unit support section.

The gear unit support section may extend farther in the direction of the rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis. This is considered advantageous insofar as the torsional stiffness and vibration strength of the carrier structure are further improved.

The carrier part may have a bottom section, which is disposed at a non-vanishing angle with respect to the carrier section, the angle between the bottom section and the carrier section in particular being greater than or equal to 90°, in particular lying between 90° and 180°, in particular between 90° and 135°, and in particular between 100° and 120°. This is considered advantageous insofar as the torsional stiffness and vibration strength of the carrier structure are further improved.

The bottom section may be situated between two carrier sections, the carrier part substantially having a U-shaped cross-section, in particular. This is considered advantageous insofar as the carrier part may be hollow between the legs of the U, thereby reducing its weight, which benefits the environment.

A torque support may be connected to the carrier structure with the aid of a torque support plate. The torque support plate is connected to the carrier part in a form-locking manner, in particular by studs, especially in a form-locking and intermaterial manner, the torque support being connected to the torque support plate in a detachable manner, in particular using a screw-type connection. This has the advantage of allowing the drivetrain package to be connected to an application with the aid of the torque support. The torque support reduces a torque acting on the drivetrain package.

The torque support plate may be connected to the carrier structure in an intermaterial and form-fitting fashion. The resistance of the torque support plate with respect to transverse forces is therefore improved since the form-locking connection makes it more difficult for the torque support plate to be torn off from the carrier part.

The carrier structure may include a sheet metal part that is at least partially situated between two gear unit support sections, the sheet metal part being implemented as a bent part. This is considered advantageous insofar as the sheet metal part further improves the torsional stiffness and the vibration strength of the carrier structure.

The sheet metal part may have edge sections that extend transversely to the direction of the rotor shaft axis.

The carrier part may be arranged in two pieces, and two halves of the carrier part are intermaterially connected to each other, in particular by a welded connection, the carrier part in particular having a linear weld seam, especially a square butt weld, which extends in the direction of the rotor shaft axis, in particular. This has the advantage of allowing the carrier part to be bent and then welded in an uncomplicated manner.

The weld seam may be interrupted by at least one recess, in particular a recess that extends farther in a direction of the rotor shaft axis than it does in a transverse direction to the direction of the rotor shaft axis. This is considered advantageous insofar as material may be saved, which makes it possible to reduce the weight of the carrier structure.

Superfluous material during the powder coating or hot-dip galvanizing may be discharged with the aid of the recess so that additional material is able to be saved.

The two halves of the carrier part may be arranged in mirror symmetry to each other. This has the advantage that a uniform application of a downward force and torque to the two halves of the carrier part is possible.

The two halves may be produced using the same punching tool. Fewer tools are therefore required, and the environmental protection is improved.

The drivetrain package may include a clutch, in particular a hydraulic clutch, the clutch connecting the rotor shaft of the motor and an input shaft of the gear unit to each other; the carrier structure may include a trough that covers the region overlapped by the clutch in the direction of the rotor shaft axis. This has the advantage that fluid escaping from the clutch can be caught with the aid of the trough and does not spray or drip onto the application. This improves the safety.

The trough may be intermaterially connected to the carrier part, in particular by welding. This is considered advantageous since the trough further improves the torsional stiffness and the vibration strength of the carrier structure.

The drivetrain package may include a fan, which is situated between the clutch and the gear unit in the direction of the rotor shaft axis, a fan wheel of the fan being connected to the input shaft of the gear unit in a torsionally fixed manner. This has the advantage of allowing the gear unit to be cooled with the aid of the fan. The drivetrain package may have a compact design, and an additional fan motor is unnecessary.

The carrier structure may have a recesses, in particular transport bores, the recesses being implemented as punched or cut recesses. This has the advantage of allowing the recesses to be punched or cut out in a single production step with the carrier part.

The recesses may be arranged as transport eyelets or arranged to accommodate forks of a forklift. This offers the advantage that the drivetrain package may be fixated with the aid of the recesses when transported. Additional transport eyelets or retroactively implemented recesses are no longer necessary.

DETAILED DESCRIPTION

FIGS. 1, 2, 9 and 10 show a drivetrain package according to an example embodiment of the present invention.

FIGS. 3, 4 and 5 show a drivetrain package according to an example embodiment of the present invention.

FIGS. 6, 7 and 8 show a drivetrain package according to an example embodiment of the present invention.

Identical parts in the exemplary embodiments have been provided with identical reference numerals.

Drivetrain package 1 shown in FIGS. 1 and 2 has a motor 2, a gear unit 3, and a carrier structure 5. It is arranged as a motor swing base.

Motor 2 includes a rotor shaft. The rotor shaft defines a direction of the rotor shaft axis. A transverse direction with respect to the direction of the rotor shaft axis is defined as the horizontal transverse direction, which extends transversely to the downward force of the drivetrain package, in particular.

Carrier structure 5 has a carrier part 15, which includes two gear unit support sections (7, 20), and two motor support parts (6, 19).

Gear unit 3 is mounted on gear unit support sections (7, 20), for which purpose gear unit support sections (7, 20) include at least one recess 25 in each case. Recess 25 may be punched, laser-cut, autogenously cut or plasma-cut in a single working step with carrier part 15.

Gear unit 3 is detachably connected to the respective gear unit support section (7, 20) with the aid of a fastening element 8, in particular a screw, which is guided through a bore in the housing of gear unit 3 and through recess 25.

Motor 2 is mounted on motor support parts (6, 19). For this purpose, motor support parts (6, 19) are provided with at least one recess 32 in each case, e.g., an elongated hole, which is punched or laser-cut in a single working step with the respective motor support part (6, 19). The elongated hole extends farther in the direction of the rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis.

Motor support parts (6, 19) extend farther in a transverse direction to the direction of the rotor shaft axis than carrier part 15. Each motor support part (6, 19) may include two recesses 32, and carrier part 15 is disposed between recesses 32 in this transverse direction to the direction of the rotor shaft axis.

Motor 2 is connected to respective motor support part (6, 19) in a detachable manner with the aid of a fastening element 9, in particular a screw, which is guided through a bore in a base part 9 of motor 2 and through recess 32.

Intermediate sheet metal sections are able to be placed between base part 9 of motor 2 and motor support parts (6, 19) for aligning the motor in a vertical direction. The sheet thickness of intermediate sheet metal sections amounts to between 1 mm and 5 mm.

Carrier part 15 is arranged as a sheet metal part. Carrier part 15 is arranged, for example, as a punched and bent sheet metal part or produced using a cutting method, in particular using a laser cutting method. Carrier part 15 may be produced in a single working step with slots and recesses in carrier part 15.

Carrier part 15 includes gear unit support sections (7, 20), two carrier sections 23, and a bottom section 24. Bottom section 24 may connect the two carrier sections 23. For example, carrier part 15 has a substantially U-shaped cross-section.

Bottom section 24 is situated at a non-vanishing angle to the respective carrier section 23. The angle between bottom section 24 and respective carrier section 23 may be greater than or equal to 90°, and in particular amounts to between 90°and 180°, in particular to between 90° and 135°, and in particular to between 100° and 120°. Bottom section 24 is situated at an angle relative to carrier section 23. An edge section 22, which extends in the direction of the rotor shaft axis, is situated between bottom section 24 and carrier section 23.

Carrier sections 23 have an edge section 21 in each case, which extends through entire carrier part 15 in the direction of the rotor shaft axis. Two subsections of each carrier section 23, which are connected to each other by edge section 21, are thus situated at a non-vanishing angle with respect to each other. This angle amounts to between 90° and 180°, in particular to between 135° and 180°, and in particular to between 150° and 170°.

Depending on the size of motor 2 and gear unit 3, the height of carrier sections 23 in the axial region of motor support parts (6, 19) is greater, smaller or the same in the axial region of gear unit support sections (7, 20). During the production process by punching or cutting, the height of carrier sections 23 is infinitely adaptable to any combination of motor 2 and gear unit 2. The sheet metal thickness of carrier structure 5 is able to be adapted to the size and weight of motor 2 and gear unit 3.

Carrier part 15 is implemented in two pieces, the two halves of carrier part 15 being arranged in mirror symmetry with respect to each other and connected to each other by welding, in particular by a linear weld seam 30, especially a square butt weld. The two halves of carrier part 15 are interconnected with the aid of a linear-type connection section, the connection section extending in the direction of the rotor shaft axis. For example, carrier part 15 has recesses along the connection section of the two halves, weld seam 30 being interrupted by the recesses, in particular.

A sheet metal part 14 is situated between the two carrier sections 23 of carrier part 15. Sheet metal part 14 is arranged as a bent part, and may have three subsections that are disposed at a non-vanishing angle with respect to one another, e.g., at a right angle, in each case. The subsections define a respective plane, two planes intersecting the third plane. The lines of intersection of the planes extend transversely to the direction of the rotor shaft axis. Sheet metal part 14 is connected to carrier part 15 in an intermaterial manner, in particular by welding.

Carrier structure 5 includes a torque support 11. Torque support 11 is connected to bottom section 24 of carrier part 15 with the aid of a torque support plate 16. For example, torque support 11 is connected to torque support plate 16 in a detachable manner using a fastening element 10, in particular a screw part.

Torque support plate 16 is connected to bottom section 24 of carrier part 15 in a form-locking manner using at least one stud and intermaterially connected by a weld joint. Torque support plate 16 may have at least one stud, which is accommodated, in particular fully accommodated, in a recess in bottom section 24.

Torque support 11 includes an uninterrupted recess that extends transversely to the direction of the rotor shaft axis.

The extension of torque support 11 in a transverse direction to the direction of the rotor shaft axis is greater than that of bottom section 24. The extension of torque support 11 transversely to the direction of the rotor shaft axis may be the same as the extension of bottom section 24. Torque support plate 16 has a greater extension in a transverse direction to the direction of the rotor shaft axis than torque support 11.

As schematically illustrated in FIG. 10, carrier part 315 is mounted on a carrier 657, in particular a steel carrier, with the aid of torque support 311. Carrier 357 includes a recess for this purpose, in particular an uninterrupted recess, into which a bolt 356 is inserted. Bolt 356 connects torque support 311 to carrier 357 in that bolt 356 is inserted into the recess in carrier 357 and, in particular, extends through this recess. Bolt 356 may be intermaterially connected, in particular welded, to carrier 357 and torque support 311.

Carrier 357 may be connected to a foundation and/or an to application that is to be driven by the drive unit.

The drivetrain package 301 is connected to an application to be driven with the aid of an output shaft 355 of the gear unit. The axis of rotation of the output shaft may extend transversely to the rotor shaft axis.

In the idle state of drivetrain package 301, the downward force of drivetrain package 301 distributes itself evenly on carrier 357, connected to drivetrain package 301 via torque support 311, and to the application, which is connected to drivetrain package 301 via output shaft 355.

In the operating state of drivetrain package 301, the load distribution changes as a function of the direction of rotation and the rotational speed of output shaft 355. As a result, either pressure forces or tractive forces are acting on torque support 311, or an equilibrium comes about between the downward force and the force that results from the torque of drivetrain package 301.

Gear unit 303 may include a flange, in particular a flange that surrounds output shaft 355 in the circumferential direction of output shaft 355. The flange makes it possible to connect gear unit 303, and thus drivetrain package 301, to an application so that in the idle condition of drivetrain package 301, the downward force of drivetrain package 301 is evenly distributed to carrier 357 and to the application connected to drivetrain package 301 with the aid of the flange.

The angle between bottom section 124 and respective carrier section 123 may be greater than or equal to 90°, and in particular amounts to between 90° and 180°, in particular to between 90° and 135°, in particular to between 100° and 120°. Bottom section 124 is disposed at an angle relative to carrier section 23. An edge section 122 is situated between bottom section 124 and carrier section 123.

Carrier sections 123 have an edge section 121 in each case, which extends through entire carrier part 115 in the direction of the rotor shaft axis. Two subsections of each carrier section 123 that are connected to each other via edge section 121 are thus disposed at a non-vanishing angle with respect to each other. This angle lies between 90° and 180°, and in particular between 135° and 180°, in particular between 150° and 170°.

Carrier part 115 is arranged in two parts, the two halves of carrier part 115 being arranged in mirror symmetry with respect to each other and interconnected by welding, in particular by a linear weld seam, especially a square butt weld.

Carrier structure (5, 105) may be provided with a corrosion-resistant coating. Carrier structure (5, 105) may be hot-dip galvanized or powder-coated.

As an alternative, the base parts and the motor support parts may be arranged as flat sheet metal parts, in the same manner as the motor support parts (206, 219).

FIG. 9 shows a detail view of FIG. 1. An alignment device 8 for aligning motor 2 relative to carrier structure 5 is situated on motor support part 19. Alignment device 8 has a bolt 50, which is partially situated in recess 33 of motor support part 19.

The bolt has a step-type taper. One step is in contact with motor carrier part 19. The tapered region of bolt 50 is inserted into and/or bonded to recess 33. As an alternative, the bolt is connected to recess 33 by screws, recess 33 being arranged as a threaded bore in this case.

As an alternative, the tapered region has a thread that is fully guided through recess 33. Bolt 50 is connected to a nut with the aid of the thread.

As an alternative, the tapered region of bolt 50 has an uninterrupted bore that is routed completely through recess 33. A splint is able to be introduced into the bore by which bolt 50 may be detachably connected to motor support part 19.

As an alternative, the tapered region of bolt 50 has a circumferential groove, which is routed completely through recess 33. A securing ring is used to connect bolt 50 to motor support part 19 in a detachable manner.

Alignment device 28 is arranged as a metal part and, in particular, made from stainless steel, e.g., V2A stainless steel. Alignment device 28 may be produced from semifinished products such as a hexagonal part, a square part, or from round steel, especially as a lathe-cut part.

As an alternative to bolt 50, a flat bar having a welded-on stud may be used, the stud being inserted into the recess, and the flat bar having a threaded bore for screw part 52.

Bolt 50 has a threaded bore to which a screw part 52 is connected by a screwed connection. Screw part 52 is in contact with motor 2. A nut 51, which may be used to secure screw part 52 relative to motor 2, is disposed on screw part 52.

Using at least one fastening element (17, 27), motor 2 is connected to motor support part 19 in a detachable manner. Base part 9 of the motor includes at least one recess for this purpose. Fastening element (17, 27) is guided through the recess in base part 9 and through recess 32.

With the aid of screw part 52, motor 2 is able to be moved in a horizontal transverse direction to the direction of the rotor shaft axis.

Using the intermediate sheet metal section, motor 2 may be moved in the vertical transverse direction.

Drivetrain package 1 may have at least two alignment devices 28 that are situated opposite each other. Motor 2 is situated in a transverse direction to the direction of the rotor shaft axis, between alignment devicesd 28. Thus, using a first alignment device 28, it is possible to press motor 2 in a first horizontal transverse direction to the direction of the rotor shaft axis, and using a second alignment device 28, it is possible to press motor 2 in a second horizontal transverse direction that extends counter to the first transverse direction.

When assembling drivetrain package 1, motor 2 is moved relative to carrier structure 5 so that the output shaft of motor 2 and the input shaft of gear unit 3 may be aligned in a coaxial manner. For this purpose, motor 2 is connected by hand to carrier structure 5 with the aid of at least one fastening element (17, 27), which is guided through a recess in base section 9 of motor 2 and through recess 32 in motor support part 19. Screw part 52 is screwed through the threaded bore in bolt 50 until screw part 52 touches base part 9 of motor 2. Screw part 52 is then further screwed so that it presses against motor 2 and shifts motor 2 in a horizontal transverse direction to the direction of the rotor shaft axis. As soon as motor 2 is aligned in the horizontal transverse direction, screw part 52 is secured against bolt 50 with the aid of nut 51, whereupon fastening element (17, 27) is fixed in place.

Alignment device 28 may then be removed again to be reused for another drive shaft package, or it may remain on the carrier structure for a renewed alignment.

Recess 33 is able to be sealed with the aid of a cover part, in particular a plastic cover part.
