摘要： A rolling deep groove ball bearing includes a bearing outer ring (1), a bearing inner ring (2), a plurality of large rolling balls (3) and special-shaped rollers (4), where the large rolling balls (3) and special-shaped rollers (4) are arranged between the bearing inner ring (1) and the bearing outer ring (2), and the large rolling balls (3) and the special-shaped rollers (4) are arranged at intervals. For the rolling deep groove ball bearing, the rolling balls (3) and the bearing raceway realize the pure rolling, where high linear velocity is subjected; the bearing capacity is large; the noise is low; the reliability is high and the service life is long. The deep groove ball bearing has no gap for installing balls and is simply assembled.

摘要： An electric machine has a stator having an array of electromagnetic elements. A rotor is mounted on bearings and has an array of rotor posts. The rotor posts each have a length defining opposed ends and the array of rotor posts extends along the rotor in a direction perpendicular to the length of each of the rotor posts. The rotor has electromagnetic elements defining magnetic poles placed between the plurality of rotor posts. An airgap is formed between the rotor and the stator when they are in an operational position. A plurality of rotor flux restrictors are formed on the rotor, and each lies adjacent to one of the opposed ends of the rotor posts.

摘要： A low-friction side load bearing assembly for accommodating severe side loads applied to a spindle is provided. The side load bearing assembly includes a sleeve member having a frustro-conical outer surface that is slidably mounted on the spindle, and a cageless rolling bearing circumscribing the sleeve member. The cageless rolling bearing includes an annular housing that contains an inner ring of ball bearings that engages the sleeve member, and an outer ring of rolling bearings that maintains angular spacing between the ball bearings of the inner ring. A spring-loaded biasing mechanism pushes the sleeve member along the axis of rotation of the spindle such that its frustroconical outer surface wedgingly engages the inner ring of ball bearings thereby obviating the need for a bearing cage and rendering the bearing assembly self-adjusting for wear.

摘要： A passenger automotive vehicle wheel bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient radial or side impact (such as a pothole or curb impact) to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and/or vibration condition in the bearing assembly. Wheel bearing assemblies according to the invention provide increased impact Brinell resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.
