A rolling bearing characterized by novel features of construction and arrangement wherein the rotational speed of the rolling bodies all have the same revolution speed under varying load conditions and even if they lie in different load zones or are of different size within reasonable tolerance limits. By this construction, the retainer pockets can be sized to provide small play for the rolling elements to enhance the guiding of the rolling bodies and eliminate undesirable noise. This, of course, eliminates force effects from the retainer for rolling elements which are larger or smaller than the nominal dimension. This is achieved by providing an oscillation ratio Gi/Gy wherein GI and Gy are the spaces between the envelope surface of the rolling body and the race track in the inner race ring and the outer ring taken along a normal to the rolling body axis located at a distance from the rolling body center of a non-loaded bearing is greater than <IMAGE> in which gamma =Dwcos alpha /dm and Dw =the rolling body diameter, alpha 32 the bearing contact angle and dm =twice the distance between the rolling body center and the bearing axis. |
