Roller bearing grip roller with release mechanism incorporates leaf spring

摘要

A grip roller release has rollers (4) which is leaf spring (6) supported against the roller grip race (5). The ends (11) of the bow-shaped spring (6) rest on the grip roller (4), with the peak of the bow (4) curve resting against the surrounding cage (10) wall. As the roller (4) advances under load towards the wall (10), the load on the spring (6) increases, increasing the leaf spring (6) area in contact with the cage wall (10). The spring (6) ends move apart, moving the load towards the roller ends.
