Wedge block type one-way bearing anti-falling device with fat storage function

Abstract

The invention relates to a wedge block type one-way bearing anti-falling device with a fat storage function for a washing machine clutch. Two lower stairs are arranged on a ball pocket base corresponding to a position on a wall body at the middle section of a through hole; two upper stairs are arranged on the ball pocket base corresponding to a position on the wall body at the top end of the through hole; the upper stairs are wider than the lower stairs; an anti-falling mechanism comprises an inner reverse buckle and an outer reverse buckle; the bottom end parts of the inner reverse buckle and the outer reverse buckle are connected to form a whole; an elastic slot is formed between the inner reverse buckle and the outer reverse buckle; a guide inclined surface is formed on the upper section of the inner side wall of the inner reverse buckle; a guide inclined surface is formed on the upper section of the outer side wall of the outer reverse buckle; and installation stairs buckled with the lower stair are arranged on the inner reverse buckle and the outer reverse buckle. By adopting a double-reverse-buckle bidirectional locking elastic press-in connection anti-falling device, the problem of falling of a wedge block of a wedge block type one-way bearing is solved; by adopting two stairs, radial locking and axial locking can be realized simultaneously; furthermore, due to the fat storage function, the lubricity of the bearing is improved, the service life of the bearing is prolonged, and noise is reduced.

Description

technical field [0001] The invention belongs to the technical field of one-way bearings, in particular to a wedge-type one-way bearing detachment prevention device with a grease storage function for a clutch of a washing machine. Background technique [0002] Most of the existing wedge-type one-way bearing wedge-preventing devices adopt circumferentially equally divided columns and holes, and use interference fit between them to prevent the wedge from being pushed out of the bearing after being subjected to axial force. There is also an application number of 200820036787.7 The single fixed sealing cover engages with the retainer as described in the detachment device. Due to the large swing of the drum of the washing machine clutch wedge type one-way bearing during work, the axial force generated during the stop is not a continuous and constant axial force, and it is very easy to make the wedge cover the axial force of the wedge. Loosening occurs under the action, and the fi...

AI Technical Summary

Problems solved by technology

Due to the large swing of the drum of the washing machine clutch wedge type one-way bearing during work, the axial force generated during the stop is not a continuous and constant axial force, and it is very easy to make the wedge cover the axial force of the wedge. Loosening occurs under the action, first part falls off or breaks, and eventually causes the device to fail

At the same time, when rotating at high speed, the grease on the spherical surface is easily taken out of the ball pocket, resulting in a decrease in bearing life and increased noise
