Abstract
A drive system includes a prime mover that provides an input, and an output system that is driven by the input. A torque transfer system is coupled between the prime mover and the output system. The torque transfer system includes two gear planes. Each of the gear planes includes a pair of gear meshes, and each of the pair of gear meshes has a floating structure.
Claims20
A drive system comprising:
- a prime mover configured to provide an input;
- an output system configured to be driven by the input;
- and
- a torque transfer system coupled between the prime mover and the output system, including at least two gear planes, wherein each of the gear planes includes a pair of gear meshes, each of the pair of gear meshes configured with a floating structure including at least one pair of gears configured to float axially on a shaft,
- wherein the floating structure comprises a spline connection with a coating configured to reduce friction.

A drive system comprising:
- a prime mover configured as a motor to provide an input;
- an output system configured as a final drive system to be driven by the input;
- and
- a torque transfer system coupled between the prime mover and the output system, the torque transfer system including two gear planes, wherein each of the gear planes includes a pair of gear meshes, each of the pair of gear meshes configured with a free floating structure to cancel axial forces in each of the two gear planes, the floating structure including a transfer shaft configured to float axially and a pair of gears configured to float axially on the transfer shaft,
- wherein the free floating structure includes a surface treatment configured to minimize friction in each of the two gear planes including between the pair of gears and the transfer shaft, wherein the surface treatment comprises at least one of a surface finish, a coating, a ball spline, and a higher diameter.
