Abstract

The invention discloses a novel washing machine speed reducing clutch comprising a clutch device. The clutch device comprises a lower shell, a split unilateral bearing and an integrated unilateral bearing. The split unilateral bearing and the integrated unilateral bearing are arranged in bearing grooves of the lower shell. A brake axle with a center hole penetrates an inner hole of the integrated unilateral bearing, and an input shaft penetrates the center hole of the brake axle. A torque transmitting shaft sleeve sleeves the input shaft. A connection plate and a connection plate spring sleeve the brake axle. An inner sleeve is fixedly connected with one end of the connection plate. A first spline is arranged on the outer wall surface of the brake axle integrally. A second spline and a third spline are arranged in an inner hole of the connection plate integrally. A fourth spline is arranged on the torque transmitting shaft sleeve integrally. Through axially movable connection between the first spline on the brake axle and the second spline on the connection plate, embedding connection or disconnection between the third spline on the connection plate and the fourth spline on the torque transmitting shaft sleeve as well as connection or disconnection between the inner sleeve and the split unilateral bearing are achieved. The novel washing machine speed reducing clutch is reasonable in structural design, simple in structure, reliable in clutch action and good in clutch effect.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a deceleration clutch for a washing machine. Background technique [0002] At present, the deceleration clutch of the pulsator-type automatic washing machine is under the washing condition. The input shaft is driven by the motor. With the frequent positive and negative rotation of the motor, the input shaft passes through the tooth shape at the end and the planetary wheel located in the inner cavity of the brake wheel. The planetary wheel frame is connected with the pulsator shaft to drive the pulsator to rotate positively and negatively to realize the washing condition. When the pulsator rotates positively and negatively, it drives the laundry to run in the same direction, thus driving the dehydration bucket with the inertia of the clothes Turn in the opposite direction. In order to overcome the counterclockwise rotation of the inner bucket, a one-way bearing is provided on th...
