Abstract
A gear joint with finished surfaces and other enhancements that allows the gear joint to accommodate higher loads. In particular, in one embodiment, the invention is a ball gear system including a ball gear having a spherical surface, a ring gear configured to receive the ball gear therein and be rotationally coupled thereto, and a thrust plate. The thrust plate is configured to be positioned adjacent to the ball gear to take up thrust forces transmitted thereto. The thrust plate has a recess configured to closely receive the spherical surface therein, and the spherical surface has a surface roughness of less than about 10 Ra in microns.
