Abstract

A modular drive system may include a motor assembly that includes a motor housing with a motor subassembly bolt pattern. The modular drive system may include a brake assembly that includes a brake housing with a brake subassembly bolt pattern. The modular drive system may include a final drive assembly that includes a final drive flange with a final drive subassembly bolt pattern.

First claim

What is claimed is:

1. A motor drive assembly for a machine, the motor drive assembly comprising:
a motor assembly that includes a motor housing with a motor subassembly bolt pattern,
wherein the motor subassembly bolt pattern permits the motor assembly to be fastened to a frame of the machine with motor subassembly bolts;

a brake assembly that includes a brake housing with a brake subassembly bolt pattern,
wherein a first portion of the brake subassembly bolt pattern matches a first portion of the motor subassembly bolt pattern to permit brake subassembly bolts to be received via the first portion of the brake subassembly bolt pattern and the first portion of the motor subassembly bolt pattern; and

a final drive assembly that includes a final drive flange with a final drive subassembly bolt pattern,
wherein a portion of the final drive subassembly bolt pattern matches a second portion of the brake subassembly bolt pattern to permit final drive subassembly bolts to be received via the second portion of the brake subassembly bolt pattern and the portion of the final drive subassembly bolt pattern, and
wherein one or more of:
the motor subassembly bolt pattern, the brake subassembly bolt pattern, and the final drive subassembly bolt pattern are configured to enable both:
the motor assembly, the brake assembly, and the final drive assembly to be individually mechanically coupled with the frame, and
a combination of the motor assembly, the brake assembly, and the final drive assembly to be mounted to the frame,

the motor subassembly bolt pattern is configured to receive the motor subassembly bolts to enable both:
the motor assembly to be mounted to the frame before the brake assembly is fastened to the motor assembly via the brake subassembly bolts, and
the motor assembly to be mounted to the frame after the brake assembly is fastened to the motor assembly via the brake subassembly bolts,

the brake subassembly bolt pattern is configured to receive the brake subassembly bolts to enable both:
the brake assembly to be mounted to the motor assembly before the motor assembly is mounted to the frame via the motor subassembly bolts, and
the brake assembly to be mounted to the motor assembly after the motor assembly is mounted to the frame via the motor subassembly bolts, or

the final drive subassembly bolt pattern is configured to receive the final drive subassembly bolts to enable both:
the final drive assembly to be mounted to the brake assembly before the brake assembly is mounted to the motor assembly via the brake subassembly bolts, and
the final drive assembly to be mounted to the brake assembly after the brake assembly is mounted to the motor assembly via the brake subassembly bolts.

2. The motor drive assembly of claim 1 , wherein the motor subassembly bolt pattern, the brake subassembly bolt pattern, and the final drive subassembly bolt pattern are configured to enable both:
the motor assembly, the brake assembly, and the final drive assembly to be individually mechanically coupled with the frame, and
the combination of the motor assembly, the brake assembly, and the final drive assembly to be mounted to the frame.

3. The motor drive assembly of claim 1 , wherein the motor subassembly bolt pattern is configured to receive the motor subassembly bolts to enable both:
the motor assembly to be mounted to the frame before the brake assembly is fastened to the motor assembly via the brake subassembly bolts, and
the motor assembly to be mounted to the frame after the brake assembly is fastened to the motor assembly via the brake subassembly bolts.

4. The motor drive assembly of claim 1 , wherein the brake subassembly bolt pattern is configured to receive the brake subassembly bolts to enable both:
the brake assembly to be mounted to the motor assembly before the motor assembly is mounted to the frame via the motor subassembly bolts, and
the brake assembly to be mounted to the motor assembly after the motor assembly is mounted to the frame via the motor subassembly bolts.

5. The motor drive assembly of claim 1 , wherein the final drive subassembly bolt pattern is configured to receive the final drive subassembly bolts to enable both:
the final drive assembly to be mounted to the brake assembly before the brake assembly is mounted to the motor assembly via the brake subassembly bolts, and
the final drive assembly to be mounted to the brake assembly after the brake assembly is mounted to the motor assembly via the brake subassembly bolts.

6. The motor drive assembly of claim 1 , wherein the frame, the motor housing, the brake housing, and the final drive flange include a same assembly bolt pattern configured to receive assembly bolts for mounting the motor drive assembly to the frame for use.

7. The motor drive assembly of claim 6 , wherein a first set of holes of the assembly bolt pattern are positioned to be a first distance from a rotational axis of the motor drive assembly, and
wherein a second set of holes of the assembly bolt pattern are positioned to be a second distance from the rotational axis of the motor drive assembly,
wherein one or more of the second set of holes are holes are angularly aligned, relative to the rotational axis, with a fluid passageway of the motor drive assembly and the first set of holes are not angularly aligned with the fluid passageway.

8. The motor drive assembly of claim 7 , wherein the first distance is longer than the second distance.

9. The motor drive assembly of claim 7 , wherein the first set of holes comprise at least eighty percent of a total quantity of holes determined from a combination of the first set of holes and the second set of holes.

10. The motor drive assembly of claim 7 , wherein one or more of the first set of holes have:
threads to secure mounting mechanism bolts associated with a mounting mechanism that is capable of maneuvering the motor drive assembly, and
an inner thread diameter, associated with the threads, that is greater than a diameter of the assembly bolts to enable the assembly bolts to bypass the threads for mounting the motor drive assembly for use.

11. A motor drive assembly for a machine, the motor drive assembly comprising:
a motor assembly that includes a motor housing with a motor subassembly bolt pattern,
wherein the motor subassembly bolt pattern permits the motor assembly to be fastened to a frame of the machine with motor subassembly bolts;

a brake assembly that includes a brake housing with a brake subassembly bolt pattern,
wherein a first portion of the brake subassembly bolt pattern matches a first portion of the motor subassembly bolt pattern to permit brake subassembly bolts to be received via the first portion of the brake subassembly bolt pattern and the first portion of the motor subassembly bolt pattern; and

a final drive assembly that includes a final drive flange with a final drive subassembly bolt pattern,
wherein a portion of the final drive subassembly bolt pattern matches a second portion of the brake subassembly bolt pattern to permit final drive subassembly bolts to be received via the second portion of the brake subassembly bolt pattern and the portion of the final drive subassembly bolt pattern,
wherein one or more of the frame, the motor housing, the brake housing, or the final drive flange include an assembly bolt pattern,
wherein a first set of holes of the assembly bolt pattern are positioned to be a first distance from a rotational axis of the motor drive assembly,
wherein a second set of holes of the assembly bolt pattern are positioned to be a second distance from the rotational axis of the motor drive assembly, and
wherein the first set o
