Abstract:
A transmission includes an input drive shaft, a drive gear, an idler gear, and a driven gear. The drive gear is rotationally fixed to the input drive shaft which, in turn, may but not necessarily, be powered by an engine. The idler gear may include a second set of gear teeth mounted to a bearing wherein the second set of gear teeth are formed from polymeric material. The second set of gear teeth for the idler gear may be in meshing engagement with the first set of gear teeth. The driven gear may include a third set of gear teeth in meshing engagement with the second set of gear teeth. The driven gear may be rotationally fixed to a pump shaft for a transmission pump. The input drive shaft, the drive gear, the idler gear, and the driven gear are configured to power a transmission pump.
