Abstract
A ball bearing for interconnecting a rotor to a stator has a plurality of balls and an inner and outer race. The inner race and the outer race have an interior surface configured to movably engage a portion of the balls, and at least one of the inner race and outer race includes a frustoconical exterior surface.
Claims15
A ball bearing for interconnecting a rotor to a stator, the ball bearing comprising:
- a plurality of balls;
- an inner race and an outer race having an interior surface configured to movably engage a portion of the balls;
- and
- wherein at least one of the inner race and the outer race includes a frustoconical exterior surface.
An axially preloaded bearing assembly for interconnecting a rotor with a stator, the bearing assembly comprising:
- at least two ball bearings configured to be mounted to different portions of the stator and adapted to be secured to different portions of the rotor;
- means for exerting an axial preload force;
- and
- means for transferring a portion of the axial preload force to a radial force.
An axially preloaded bearing assembly for interconnecting a rotor with a stator, the bearing assembly comprising:
- a first ball bearing and a second ball bearing configured to be secured to different portions of the rotor;
- a preload mechanism disposed adjacent the first ball bearing and adapted to apply an axial preload force thereto;
- the stator and the second ball bearing configured with frustoconical surfaces which firmly abut each other to transfer a portion of the axial preload force to a radial preload force.
