POLYMERIC GEAR

The issue of the invention is a polymeric gear. 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. 本发明题为"聚合物齿轮"。本发明公开了一种变速器，该变速器包括输入驱动轴、驱动齿轮、空转齿轮和从动齿轮。驱动齿轮旋转地固定到输入驱动轴，该输入驱动轴又可以但并非必须由发动机提供动力。空转齿轮可以包括安装到轴承的第二组齿轮齿，其中第二组齿轮齿由聚合物材料形成。用于空转齿轮的第二组齿轮齿可以与第一组齿轮齿啮合接合。从动齿轮可以包括与第二组齿轮齿啮合接合的第三组齿轮
