Reduction clutch for washing machine and washing machine

Abstract

The invention discloses a reduction clutch for a washing machine and the washing machine. The reduction clutch comprises an input shaft, an input shaft sleeve, a brake wheel, a reducer, a dewatering shaft, an output shaft, a clutch device and a shell. The input shaft sleeve is installed on the input shaft in a sleeving mode, the dewatering shaft is installed on the output shaft in a sleeving mode, the reducer is installed on an inner cavity of the brake wheel, and the input shaft, the input shaft sleeve, the brake wheel and the output shaft are connected with the reducer. The reducer is a double planetary gear train and comprises a first planetary gear train and a second planetary gear train. The input shaft sleeve and a carrier of the second planetary gear train are connected into one, and the dewatering shaft and the brake wheel are connected into one. When the washing machine is in a washing state, the clutch device brakes the input shaft sleeve and controls the output shaft and the dewatering shaft to rotate reversely in two directions. When the washing machine is in a dewatering state, the clutch device relieves the brake on the input shaft sleeve and controls the output shaft and the dewatering shaft to rotate in the same single direction. The reduction clutch for the washing machine and the washing machine have the advantages that the structure is simple and compact, the manufacturing cost is low, the transmission is safe, reliable and efficient, the service life is long, and the noise is low.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine deceleration clutch and a washing machine. Background technique [0002] At present, the function of the deceleration clutch of the pulsator type washing machine is generally to drive the pulsator to reciprocate after decelerating the bidirectional rotation of the motor. The conventional deceleration clutch is mainly composed of an input shaft, an output shaft, an output shaft sleeve, an input shaft sleeve, a brake wheel, a reduction mechanism installed inside the brake wheel, and a clutch component installed on the input shaft sleeve. In washing conditions, the output shaft is required to rotate repeatedly at low speed in both directions. The output shaft sleeve and the brake wheel are integrated. The deceleration mechanism generally only plays a simple deceleration role. When the brake wheel is braked, the output shaft sleeve is also restrained. The two-way ro...

Problems solved by technology

[0006] However, in the washing machine with the above-mentioned deceleration clutch, the inner tub and the pulsator frequently run in opposite directions, and the moment of inertia generated by the inner tub directly acts on the overrunning clutch. quality problem

During the rotation of the inner tub, the one-way bearing will often have a reverse force, and the one-way bearing is prone to failure. At the same time, the clutch spring will be tightened during washing, resulting in damage to the clutch spring; The driving wheel is separated and connected to the reducer. The inner drum swings in the dehydration state, which directly acts on the dehydration shaft. The dehydration shaft is eccentric, causing the washing machine to vibrate and produce noise.
