Abstract

A carrier for a motor subassembly of a hydraulic motor is provided that enables multiple components of the motor subassembly to be temporarily bundled into a compact and easy-to-transport motor subassembly kit. The carrier is a non-hydraulically-functioning member that is configured to have one or more features that mimic a corresponding one or more features of a hydraulically-functioning motor housing to which motor subassembly is intended to be coupled for forming the hydraulic motor. The carrier may have a body with a recessed portion that is configured to receive and/or enclose one or more components of the motor subassembly, and which may cooperate with the one or more motor subassembly components to temporarily secure and bundle the motor subassembly as a compact kit, thereby facilitating transportation and handling of the subassembly components.

First claim

What is claimed is:

1. A motor subassembly kit for a hydraulic motor, the kit comprising:
a hydraulically-operable motor subassembly having a plurality of motor components that are configured to be operably coupled to a hydraulically-operable motor housing for at least partially forming the hydraulic motor; and
a non-hydraulically-operable carrier for carrying the motor subassembly;
wherein the carrier cooperates with the motor subassembly to temporarily secure the plurality of motor components of the motor subassembly as a transportable bundle,
wherein the carrier has one or more portions that mimic a corresponding one or more portions of the hydraulically-operable motor housing, thereby facilitating transportation of the plurality of motor components in the transportable bundle,
wherein the plurality of motor components includes fasteners configured to be received within corresponding housing receivers disposed at preexisting locations of the hydraulically-operable motor housing for securing the motor subassembly to the hydraulically-operable motor housing, and
wherein the one or more portions of the non-hydraulically-operable carrier that mimic the hydraulically-operable motor housing include carrier receivers disposed at locations that correspond with the preexisting locations of the housing receivers, and that receive the fasteners to secure the plurality of motor components as the transportable bundle.

2. The motor subassembly kit according to claim 1 , wherein the carrier includes a body having a nose portion, a base portion, and an intermediate portion extending between the nose portion and the base portion;
wherein the carrier has an opening in the base portion for receiving one or more of the plurality of motor components, and
wherein the carrier has a recessed portion that extends inwardly into the body from the opening in the base portion toward the nose portion to form an enclosure for at least partially containing the one or more motor components.

3. The motor subassembly kit according to claim 2 , wherein the carrier is devoid of fluid ports for transferring pressurized hydraulic fluid.

4. The motor subassembly kit according to claim 1 , wherein the carrier includes a nose portion, a base portion, and an intermediate portion extending between the nose portion and the base portion,
wherein the carrier has an opening in the base portion for receiving the fasteners, and the carrier has a recessed portion that extends inwardly into the body from the opening in the base portion toward the nose portion to form an enclosure for at least partially containing the fasteners; and
wherein the carrier receivers are disposed within the recessed portion in the intermediate portion of the body, the carrier receivers having threaded portions for threadably receiving the fasteners.

5. The motor subassembly kit according to claim 1 , wherein a body of the carrier is made of plastic, and the carrier receivers are metal inserts in the body, the metal inserts having internal threads for threadably receiving the fasteners.

6. The motor subassembly kit according to claim 1 , wherein the plurality of motor components includes an end cover with end cover receivers, the end cover receivers receiving the fasteners along a longitudinal axis of the motor subassembly to sandwich the other plurality of motor components between the carrier and the end cover.

7. The motor subassembly kit according to claim 1 , wherein the carrier includes a flange, and
wherein the one or more portions of the non-hydraulically-operable carrier that mimic the hydraulically-operable motor housing include support regions at locations on the flange that correspond with locations of support regions of the hydraulically-operable motor housing, such that the support regions of the carrier can facilitate transportation of the bundle in existing dunnage.

8. The motor subassembly kit according to claim 7 , wherein the flange has detents, through-holes, and/or surface texturing for providing locator structures that facilitate assembly of the motor subassembly in a manufacturing environment and/or facilitate transportation of the motor subassembly bundle.

9. The motor subassembly kit according to claim 1 , wherein the plurality of motor components includes a torque transferor,
wherein a body of the carrier includes a nose portion, a base portion, an intermediate portion between the nose portion and the base portion, and a recess that extends inwardly into the body from the base portion toward the nose portion to form an enclosure for containing one or more of the plurality of motor components; and
wherein a bottom portion of the recess proximal the nose portion of the body is configured to contain the torque transferor.

10. The motor subassembly kit according to claim 9 , wherein the nose portion of the body is tapered and includes scallops for minimizing weight of the carrier.

11. The motor subassembly kit according to claim 1 , wherein the plurality of motor components of the motor subassembly includes: a torque transferor, a torque generator, and a fluid manifold.

12. The motor subassembly kit according to claim 11 , wherein the motor subassembly is a gerotor configuration;
wherein the torque transferor is a longitudinally extending drive link having a plurality of teeth;
wherein the torque generator is a rotor assembly;
wherein the motor subassembly further includes a commutator and a thrust bearing.

13. A motor subassembly kit for a hydraulic motor, the kit comprising:
a hydraulically-operable motor subassembly having a plurality of motor components that are configured to be operably coupled to a hydraulically-operable motor housing for at least partially forming the hydraulic motor; and
a non-hydraulically-operable carrier for carrying the motor subassembly;
wherein the carrier cooperates with the motor subassembly to temporarily secure the plurality of motor components of the motor subassembly as a transportable bundle, wherein the carrier has one or more portions that mimic a corresponding one or more portions of the hydraulically-operable motor housing, thereby facilitating transportation of the plurality of motor components in the transportable bundle,
wherein the carrier includes a flange,
wherein the one or more portions of the non-hydraulically-operable carrier that mimic the hydraulically-operable motor housing include support regions at locations on the flange that correspond with locations of support regions of the hydraulically-operable motor housing, such that the support regions of the carrier can facilitate transportation of the bundle in existing dunnage, and
wherein the carrier includes a nose portion, a base portion, and an intermediate portion between the nose portion and the base portion, wherein the base portion has an opening for receiving one or more of the plurality of motor components, and wherein the flange is located at the intermediate portion.

14. The motor subassembly kit according to claim 13 , wherein the base portion includes one or more circumferentially extending slots that extend axially from the opening toward the nose portion for facilitating removal of the motor subassembly from the carrier.

15. A motor subassembly kit for a hydraulic motor, the kit comprising:
a hydraulically-operable motor subassembly having a plurality of motor components that are configured to be operably coupled to a hydraulically-operable motor housing for at least partially forming the hydraulic motor; and
a non-hydraulically-operable carrier for carrying the motor subassembly;
wherein the carrier cooperates with the motor s
