Title: Bearing attaching method
Inventor: HAMAGUCHI TAKASHI
IPC: F16C19/46
Filed: 2020-03-18
Abstract: To solve a problem with a conventional method of attaching a bearing to a housing that either an inner bearing ring or an outer bearing ring is directly fixed to a housing, but when one of the bearing rings of the bearing is fixed to the housing, there occurs rotational resistance between rolling elements and the bearing ring on a rotation side.SOLUTION: A bearing, which is conventionally fixed direct to a housing, is now attached to the housing so that both an inner bearing ring and an outer bearing ring are freely rotatable. By making both the inner bearing ring and the outer bearing ring rotatable with respect to the housing, moving distances of the inner bearing ring and the outer bearing ring in which rolling elements rotationally move are made the same, thereby preventing rotational resistance from occurring in the rolling elements.SELECTED DRAWING: Figure 1
