Abstract
Systems and methods are provided for a compound bearing assembly including an offset coupler supporting an inner bearing and an outer bearing for distributing a rotational loading of the compound bearing assembly. In some embodiments, at least one of the bearings comprises a bearing cage with a plurality of elongated openings for receiving a respective plurality of balls. The compound bearing assembly is configured to support a drive shaft of a supercharger system of a vehicle or some other rotational system.
Claims20
A compound bearing assembly for supporting a drive shaft within a vehicle supercharger system, said drive shaft extending along a longitudinal axis, the compound bearing assembly comprising:
- an inner bearing surrounding the drive shaft, the inner bearing comprising:
- an inner bearing inner race;
- an inner bearing outer race surrounding the inner bearing outer race;
- an inner bearing cage comprising a plurality of elongated openings for allowing oil flow within the inner bearing;
- and
- a plurality of inner bearing balls disposed within the respective plurality of elongated openings of the inner bearing cage;
- an outer bearing comprising:
- an outer bearing inner race;
- an outer bearing outer race adapted to be coupled to a frame of the vehicle supercharger system;
- an outer bearing cage;
- and
- a plurality of outer bearing balls disposed within the outer bearing cage;
- and
- an offset coupler coupled to each of the inner bearing and the outer bearing, the offset coupler supporting the inner bearing outer race and the outer bearing inner race,
- wherein the offset coupler positions the inner bearing and the outer bearing such that the outer bearing is offset along the longitudinal axis with respect to the inner bearing to distribute a load from the drive shaft and to provide an oil flow path between the inner bearing and the outer bearing.
A compound bearing assembly for supporting a drive shaft within a rotational system, the compound bearing assembly comprising:
- an inner bearing connected to the drive shaft, the inner bearing comprising:
- an inner bearing housing comprising an inner bearing inner race and an inner bearing outer race;
- an inner bearing cage disposed within the inner bearing housing, the inner bearing cage including a plurality of elongated elliptical openings for allowing oil flow within the inner bearing;
- and
- a plurality of inner bearing balls disposed within the inner bearing cage;
- an outer bearing comprising:
- an outer bearing housing comprising an outer bearing inner race and an outer bearing outer race adapted to be coupled to a frame of the rotational system;
- an outer bearing cage disposed within the outer bearing housing;
- and
- a plurality of outer bearing balls disposed within the outer bearing cage;
- and
- a coupler connecting the inner bearing to the outer bearing, the coupler secured to the inner bearing outer race and the outer bearing inner race, wherein the coupler provides an oil flow path between the inner bearing and the outer bearing.
A compound bearing assembly for supporting a drive shaft having a longitudinal axis within a rotational system, the compound bearing assembly comprising:
- an inner bearing coupled to the drive shaft, the inner bearing comprising:
- an inner bearing housing including an inner bearing inner race and an inner bearing outer race;
- an outer bearing comprising:
- an outer bearing housing including an outer bearing inner race and an outer bearing outer race configured to be coupled to a frame of the rotational system;
- and
- an offset coupler coupled to each of the inner bearing and the outer bearing, the offset coupler supporting the inner bearing outer race of the inner bearing and the outer bearing inner race of the outer bearing,
- wherein the offset coupler positions the inner bearing and the outer bearing such that the outer bearing is offset along the longitudinal axis with respect to the inner bearing to distribute a load from the drive shaft and to provide an oil flow path between the inner bearing and the outer bearing.
