Abstract
In one embodiment, a gear system includes two cycloidal gears coupled to an eccentric drive shaft via a cartridge bearing. Each of the two cycloidal gears includes a number N of pockets on a surface of the gears to receive a ball bearing in the respective pocket. The N pockets on the surface of a first cycloidal gear of the two cycloidal gears are substantially aligned with the N pockets on the surface of a second cycloidal gear of the two cycloidal gears. Each of the two cycloidal gears further includes a lip coupled to the cartridge bearing. The gear system includes a number N of ball bearings disposed in the N pockets of the two cycloidal gears, where the ball bearings maintain a distance between the two cycloidal gears. The ball bearings cause the respective cycloidal gear to be flush with the cartridge bearing coupled to the eccentric shaft.
