PROBLEM TO BE SOLVED: To provide a retainer for a single row ball turning bearing capable of preventing plastic deformation of a segment end portion and smoothly gyrating. SOLUTION: Pockets housing a number of balls in a single row are arranged in an inside of segments arranged in a ring-shape between an inner ring and outer ring and divided at a circumferential direction, and half pockets 11a are also arranged at both end of the segment. A pocket 11b between each end of segments is formed by butting respective half pockets of each segment. The pockets are arranged in an inequitable state so that an internal P 1 between the half pocket 11a and an adjacent pocket 11 is set greater than an interval arranged in a conventional retainer as an uniform interval of pockets, and so that an interval P 2 inside the segment 9 is set smaller than a conventional pocket interval. Thus, plastic deformation of both the ends of the segment 9 can be prevented without decreasing load capacity of the bearing, and smooth gyration of the retainer can be obtained in stable torque.

PROBLEM TO BE SOLVED: To provide an excellent rolling bearing to durability with easy oil feeding and sealing by making an agitation resistance of lubricant small and restraining rise and variation of rotation torque as well as a calorific value. SOLUTION: In an outer ring 2, an inner ring 3 and a rolling bearing consisting of plural rolling movers 5 that roll these planes of track, a compressed coil spring 6 for keeping those intervals among each rolling mover 5 is equipped with. The absorber such as a sponge 7 absorbing and maintaining lubricating oil is incorporated in this coil spring 6, and the sponge 7 is expanded and contracted along with expansion and contraction of the coil spring 6 and the lubricating oil absorbed and maintained runs and come out by going forward and delaying of a revolution motion of the rolling mover 5. Thus, the planes of track 4a, 4b are lubricated. Thereby, the agitation resistance of the lubricant becomes smaller in comparison with conventional grease lubrication and the fine rolling bearing of durability can be realized limiting temperature rise due to low and stable rotation torque as well as small calorific value.

PROBLEM TO BE SOLVED: To reduce a diameter, and delicately adjust torque by forming a torque limiter of a torque generating spring and a torque adjusting spring installed in an inner ring with a required fastening margin, and butting the inside ends of both springs against each other. SOLUTION: When an inner ring 11 rotates in the winding direction of a coil spring 12, respective springs 12a, 12b of the coil spring 12 are dragged in the rotational direction. Therefore, since diametrically expanding directional force respectively acts on the torque adjusting spring 12b and the torque generating spring 12a, respective fastening binding forces are restricted, so that the inner ring 11 rotates while generating constant torque. While, when the inner ring 11 rotates in the reverse direction, the respective springs 12a, 12b rotate together in the direction, so that the tightly fastening forces increase. In this case, since a hook 25 of the torque generating spring 12a is engaged with an engaging hole 17 of an outside member 13, the inner ring 11 is locked by fastening binding force of the coil spring 12a. That is, a torque limiter acts as a one-way torque limiter. COPYRIGHT: (C)1999,JPO
