Frequency-conversion hand-rubbing motor reducing clutch device and washing machine

Abstract

The invention relates to a frequency-conversion hand-rubbing motor reducing clutch device which comprises a clutch shaft sleeve and a poking fork contacted with the clutch shaft sleeve, wherein relative motion exists between the poking fork and the clutch shaft sleeve; and lubricating grease is applied on a contact face between the poking fork and the clutch shaft sleeve, so slide friction force between the poking fork and the clutch shaft sleeve is reduced. The invention also relates to a washing machine, wherein the frequency-conversion hand-rubbing motor reducing clutch device is disposed on the washing machine. According to the invention, the lubricating grease is applied on the contact face between a positioning convex part and the poking fork, so slide friction force between the poking fork and the positioning convex part is reduced; slide speed of the poking fork is increased; vertical slide speed of the clutch shaft sleeve is increased; separation and approaching speeds of a dewatering shaft and a rotor are increased; the difference between rotation time of a washing bucket and set time is reduced; abnormal friction sounds are reduced; reliability of the reducing clutch device is enhanced; and users' experience effects are improved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a decelerating clutch device for a frequency-variable hand-rubbing motor. Background technique [0002] The existing deceleration clutch device includes a frequency conversion motor composed of a rotor and a stator, and an input shaft whose lower part is connected to the rotor through a nut. The outer sleeve of the input shaft is provided with an input shaft sleeve, and an oil-impregnated bearing is arranged between the input shaft and the input shaft sleeve. , so that the input shaft can rotate axially relative to the input shaft sleeve. The outer sleeve of the input shaft sleeve is provided with a clutch sleeve. The clutch sleeve cannot rotate axially relative to the input sleeve, but can slide up and down in the axial direction. The clutch sleeve Sliding down, the clutch bushing is connected with the rotor, the input bushing rotates with the rotation of the clutch bushing, the ...

Problems solved by technology

[0004] Since the shift fork moves up and down by rotating around the shaft, when the shift fork pushes the positioning protrusion upward, the shift fork slides from one side of the positioning protrusion to the other side of the positioning protrusion. In the above process, the shift fork and the positioning protrusion The large sliding friction between the positioning protrusions causes the sliding speed of the shift fork to be slower, the speed of the clutch sleeve to slide upwards is slower, the speed of separation of the input sleeve and the rotor is slower, and in the washing machine, it will cause the rotation time of the washing tub Longer, affecting the use of the washing machine

On the contrary, when the shift fork no longer pushes up the positioning protrusion, the shift fork returns to the initial position. In the above process, the sliding friction between the shift fork and the positioning protrusion is large, resulting in a slow sliding speed of the shift fork, and the clutch The sliding speed of the shaft sleeve is slow, and the speed of the input shaft sleeve and the rotor is relatively slow. In the washing machine, the rotation time of the washing tub will be shortened, which will affect the dehydration effect of the clothes, and may also cause the blockage of the clutch sleeve. washing machine not working properly
