Anti-friction bearing for use in pulley or pulley wheel for e.g. guiding belt, has rolling bodies arranged between inner ring and outer ring, where bodies are held in recesses that are non-uniformly distributed over circumference of cage

摘要

The bearing (1) has rolling bodies (4, 7) e.g. balls and cylinders, arranged between an inner ring (3) and an outer ring (2), where the rolling bodies are held in recesses (6, 8) of a cage (5). The recesses are non-uniformly distributed over a circumference of the cage, where distances between adjacent recesses are different. Angles formed between a connecting line of one of the rolling bodies to a center of the bearing and another connecting line of the adjacent rolling body to the center are different.
