摘要： In a rolling bearing including an inner race; an outer race; a plurality of rolling elements rollingly arranged between the inner race and the outer race; and a cage holding the rolling elements, the cage has an annular shape and a plurality of pockets which are formed at plural positions in a circumferential direction of the cage, in which each of the pockets has an opening peripheral portion which is curved to a direction of increasing a distance from a center of the rolling elements. The opening peripheral portion forms a chamfered face or a convex face. The rolling bearing can sufficiently ensure the lubrication of sliding contact portions between the cage and rolling elements so that vibrations and noises of the rolling bearing are lowered.

摘要： The frequencies generated based on the undulations existing on the inner and outer ring raceways 8, 10 and on the rolling surface of the balls 11, 11 are out of coincidence with the rotational frequency itself of the rotation member supported by the rolling bearing, and with a frequency component which is a multiple of the rotational frequency, or kinds of frequencies generated due to the undulations are out of coincidence with each other in the natural frequency domain of a rotation system which is a rotation supporting portion having the rolling bearing incorporated therein, whereby without using a special grease, the self-excited frequency of the rolling bodies hardly grows to abnormal vibration, and a rolling bearing having sufficient durability and causing no abnormal vibration and noise even if used at low temperature is realized.

摘要： The pocket surface of a pocket with a ball stored therein has a pair of first pocket surfaces respectively formed inside a pair of pawls and a second pocket surface situated between the two first pocket surfaces. The second pocket surface is formed as a spherical-shaped concave surface having a radius of curvature the center of curvature of which is the rotation center of the ball in a no-load state. Each of the first pocket surfaces has a center of curvature shifted from the center of curvature of the second pocket surface toward the opposite side to the entrance (opening) of the pocket by an axially shifting quantity h1, and each of the first pocket surfaces is formed, starting from the present center of curvature, as a spherical-shaped concave surface with its radius of curvature set larger than the radius of curvature of the second pocket surface.

摘要： A rolling bearing unit having undulation on the rolling surfaces of the rolling elements where the total value of the wave components having an even number of waves per circumference is smaller than the total value of the wave components having an odd number of waves per circumference, or having undulation on the inner ring raceway and outer ring raceway, where the undulation on at least one of the raceway is conditioned such that the maximum waviness amplitude among (nZ), (nZ+1) and (nZ -1) waves per circumference is smaller than the maximum waviness amplitude among (nZ+2) and more waves per circumference, where n is a positive integer and Z is the number of rolling elements, thereby making it possible to obtain a low-cost, high-performance rolling bearing in which the vibration characteristics of the rolling bearing are improved without having to increase the precision required for manufacturing the rolling elements and inner ring raceway and outer ring raceways.
