Abstract
A thrust bearing and coupling component includes a fixed ring fastened to an inner surface of the housing and an orbiting ring fastened to an axial end surface of the end plate of the orbiting member facing the fixed ring. The fixed and orbiting rings have a plurality of corresponding circular pockets, each pocket on the fixed ring faces a pocket on the orbiting ring corresponding in size, pitch, and radial distance. A ball bearing is placed within each facing pair of corresponding pockets. The corresponding pockets interact with the ball bearings to prevent rotation of the orbiting member during orbital motion. The circular pockets include rounded corners formed at the open end thereof which interact non-abrasively with the ball bears. Thus, the rotation preventing and thrust bearing device may be easily constructed and manufactured, and its components may exhibit a longer life.
