Abstract

According to an embodiment, a sliding gear mesh includes a chassis, a prime mover mounted on the chassis and fixed in position relative to the chassis, a prime drive gear coupled with the prime mover and driven to rotate by the prime mover, and a sliding gear assembly. The sliding gear assembly includes a sliding drive gear that meshes with the prime drive gear. The sliding gear assembly is slidably mounted on the chassis to slide toward and away from the prime drive gear to adjust a mesh between the sliding drive gear and the prime drive gear.

Claims

1. A sliding gear mesh comprising:

a chassis;

a prime mover mounted on the chassis and fixed in position relative to the chassis;

a prime drive gear coupled with the prime mover and driven to rotate by the prime mover; and

a sliding gear assembly comprising a sliding drive gear that meshes with the prime drive gear, the sliding gear assembly being slidably mounted on the chassis to slide toward and away from the prime drive gear to adjust the mesh between the sliding drive gear and the prime drive gear.

2. The sliding gear mesh of claim 1, wherein the prime mover comprises a motor.

3. The sliding gear mesh of claim 1, wherein the prime mover comprises an engine.

4. The sliding gear mesh of claim 1, wherein the sliding drive gear comprises a spur gear.

5. The sliding gear mesh of claim 1, wherein the sliding drive gear is rotationally coupled with an axle to rotate the axle about an axis of rotation when the sliding drive gear rotates about the same axis of rotation.

6. The sliding gear mesh of claim 1, wherein the sliding drive gear is rotationally coupled with a differential to rotate a pair of axles along a common axis of rotation when the sliding drive gear rotates.

7. The sliding gear mesh of claim 1, wherein the prime mover is fixedly mounted on the chassis by a plurality of fasteners.

8. The sliding gear mesh of claim 7, wherein the plurality of fasteners includes a fixing fastener that passes through a substantially symmetrical hole in the chassis.

9. The sliding gear mesh of claim 8, wherein the substantially symmetrical hole is slightly larger than a width of the fixing fastener to constrain lateral movement of the fixing fastener relative to the chassis.

10. The sliding gear mesh of claim 8, wherein the fixing fastener includes a fastener selected from the group consisting of a screw, a rivet, a bolt, a nut, a lever, a knob, a clamp, a clip, a latch, toggle fastener, and a pin.

11. The sliding gear mesh of claim 1, wherein the sliding gear assembly is mounted on the chassis by a fixing fastener.

12. The sliding gear mesh of claim 11, wherein the fixing fastener alternately fixes the sliding gear assembly in position relative to the chassis by friction between the chassis and the sliding gear assembly when the fixing fastener is in a tightened state and facilitates lateral movement of the sliding gear assembly relative to the chassis and prime drive gear when the fixing fastener is in a loosened state.

13. The sliding gear mesh of claim 11, wherein the fixing fastener passes through a substantially oblong hole in a sliding plate of the sliding gear assembly and fastens to the chassis, the fixing fastener alternately fixing the sliding gear assembly in position relative to the chassis when the fixing fastener is in a tightened state and facilitating lateral movement of the sliding gear assembly relative to the chassis and prime drive gear when the fixing fastener is in a loosened state.

14. The sliding gear mesh of claim 13, wherein the oblong hole is slightly larger than a width of the fixing fastener in a first direction and significantly larger than a width of the fixing fastener in a second direction perpendicular to the first direction to substantially restrict the lateral movement of the fixing fastener relative to the chassis and prime drive gear to the second direction.

15. The sliding gear mesh of claim 14, wherein the second direction is aligned to guide lateral movement of the sliding drive gear toward and away from the prime drive gear.

16. The sliding gear mesh of claim 11, wherein the fixing fastener includes a fastener selected from the group consisting of a screw, a rivet, a bolt, a nut, a lever, a knob, a clamp, a clip, a latch, toggle fastener, and a pin.

17. The sliding gear mesh of claim 1, wherein the prime drive gear is fixed in position relative to the prime mover.

18. A method of adjusting a mesh between a prime drive gear of a prime mover and a sliding drive gear of a sliding gear assembly, wherein the prime mover is mounted on a chassis and fixed in position relative to the chassis, the prime drive gear is coupled with the prime mover and driven to rotate by the prime mover, and the sliding gear assembly comprising the sliding drive gear is slidably mounted on the chassis to slide toward and away from the prime drive gear, the method comprising:

loosening a fixing fastener that fastens the sliding gear assembly to the chassis;

sliding the sliding gear assembly toward or away from the prime mover; and

tightening the fixing fastener that fastens the sliding gear assembly to the chassis.

19. The method of claim 18, wherein sliding the sliding gear assembly comprises sliding the fixing fastener along a length of an oblong hole in a sliding plate of the sliding gear assembly that is aligned to guide lateral movement of the sliding drive gear toward and away from the prime drive gear.

20. The method of claim 18, wherein sliding the sliding gear assembly comprises sliding the fixing fastener along a guide rail that is aligned to guide lateral movement of the sliding drive gear toward and away from the prime drive gear.
