摘要: It is intended to suppress rattling in the fitted state of segments to improve operating efficiency in bonding the segments together. A cage composed of a plurality of arcuate segments, wherein a joining projection formed in the bonding section of one of adjacent segments is fitted in a joining recess formed in the bonding section of the other to thereby annularly bond the segments. In this cage, said joining projection and joining recess have tapered fitting surfaces as seen in a radial section, and the two fitting surfaces are closely contacted and joined together.

摘要: The designing of an annular integral type is established by forming a cage of a resin material that satisfies the condition (a) that the ratio of its linear expansion coefficient to that of bearing steel is not more than 2 or the condition (b) that its water absorption percentage is not more than 0.5%, or both conditions (a) and (b), thereby preventing the occurrence of abnormal sounds by stabilizing the behavior of a segment type cage for an ultrathin-walled rolling bearing.

摘要: Problems of an acoustic trouble and a bearing lock are solved by securing a guide clearance of a plastic cage (18) of a rolling bearing (10).The plastic cage (18) is divided at a part in a circumferential direction to provide an opening section (20). The circumferential length of the opening section (20) is set to the sum total of an extension by temperature variation, an extension by variation in water absorption, and a circumferential length for securing the guide clearance.

摘要: A rolling bearing (100) is provided with a dynamic damper (60). A natural frequency of the dynamic damper (60) is caused to coincide with a natural frequency of vibration generated in an entire device. Consequently, it is possible to effectively suppress the vibration generated in the device.
