<P>PROBLEM TO BE SOLVED: To provide a rolling bearing capable of improving the effect to viscous coupling between a cage and an inner race by the centrifugal effect. <P>SOLUTION: This rolling bearing is provided with the inner race 3, an outer race 2, and arrangement of rolling elements 4 positioned between the two races 2 and 3 and arranged in the bearing cage 5. An inner face of the bearing cage 5 is guided on the inner race 3 so as to limit eccentric motion of the cage 5 in the bearing 1, and a reservoir 9 formed between a pair of gates 6a and 7b provided in the cage 5 in the peripheral direction is also provided. An outer face of the inner race 3 includes a raised land 3d coming into contact with oil in the reservoir 9. Consequently, depth in the radial direction of each of the gates 6b, 7b is larger than the size of the maximum clearance in the radial direction between the land 3d and the cage 5 in order to control relative speed between the cage 5 and the inner race 3 and maintain the control and contact between the land 3d and the oil while the cage 5 moves eccentrically. <P>COPYRIGHT: (C)2010,JPO&INPIT |
