摘要

The assembly has a bearing (32), a shaft (41) with an end (421) and a slot (42), and two engaged rings (45, 46) placed in the slot of the shaft. The engaged ring (45) is made of a metallic material, and the engaged ring (46) is made of a non-metal material such as polymer. The material strength of the engaged ring (45) is larger than that of the engaged ring (46). The engaged ring (45) is used to support and position the shaft, and the engaged ring (46) is used to dampen the shaft.
