Washing machine

摘要

Disclosed herein is a washing machine that is capable of increasing a frictional force between an outer diameter of a rotary shaft and an inner race of a bearing to prevent the sliding between the rotary shaft and the bearing due to a gap between the outer diameter of the rotary shaft and the inner race of the bearing, thereby preventing creep noise from the rotary shaft. The washing machine includes at least one elastic member disposed between the outer diameter of the rotary shaft and the inner race of the bearing to prevent noise due to the sliding between the rotary shaft and the bearing.

主权项

1. A washing machine comprising:
a water tub; a rotary tub rotatably installed in the water tub; a drive motor to rotate the rotary tub; a rotary shaft to transmit a drive force from the drive motor to the rotary tub; and a bearing housing supporting a bearing to rotatably retain the rotary shaft, the bearing having an inner race to rotate together with the rotary shaft, an outer race affixed to the bearing housing, and a plurality of balls movably disposed between the inner race and the outer race, wherein an elastic member is configured to exert pressure to the inner race of the bearing and the outer diameter of the rotary shaft to constrain a sliding between the rotary shaft and the inner race of the bearing to reduce noise and vibration of the washing machine, and wherein the elastic member comprises an annular leaf spring adapted to uniformly maintain a gap formed between the inner race of the bearing and the outer diameter of the rotary shaft and to increase a friction force between the rotary shaft and the inner race of the bearing such that a sliding between the rotary shaft and the inner race of the bearing is constrained.
