ABSTRACT:
The present invention discloses an orbiting member fluid displacement apparatus including a rotation preventing and thrust bearing device. The rotation preventing and thrust bearing device includes a fixed portion, an orbital portion, and bearing elements. The fixed portion includes a first annular race and a first ring, which are formed separately. The first annular race is placed in a loose fit within a first annular step in an inner surface of the housing and the first ring is attached to the housing. The orbital portion includes a second annular race and a second ring, which also are formed separately. The second annular race is placed in a loose fit within a second annular step in an end plate of the orbiting member and the second ring is attached to the end plate of the orbiting member. A plurality of pockets are formed in the rings and face one another in substantially aligned pairs. A bearing element is received in each aligned pair of pockets to prevent the rotation of the orbiting member by the bearing elements interacting with the first and second rings and to bear the axial thrust load from the orbiting member. One or more lubricant conductive grooves are formed at first contacting surfaces between the first annular race and the housing or second contacting surfaces between the second annular race and the orbiting member, or both.
