  • Scroll compressor with rolling element bearings
    Patent number: 12729683
    Abstract: A scroll compressor includes a housing and a rotatable drive shaft disposed within the housing and having an eccentric end portion. First and second support bearings rotatably couple the drive shaft with the housing and each includes a plurality of rolling elements, at least one of which is ceramic, and an annular cage formed of a polymeric material. A scroll member is disposed within the housing chamber and a drive bearing rotatably couples the shaft eccentric portion with the scroll member such that the scroll member orbits about the central axis. The drive bearing includes a plurality of rolling elements, at least one of which is ceramic, and an annular cage formed of a polymeric material. Further, a solution formed of refrigerant and oil is directed to each one of the drive bearing and the first and second support bearings so as to lubricate the rolling elements.
