Dual-power direct-drive clutch of washing machine

Abstract

The invention relates to the technical field of washing machines, in particular to a dual-power direct-drive clutch of a washing machine. The dual-power direct-drive clutch comprises an upper shaft sleeve and a planetary gear train, wherein the planetary gear train comprises a drive plate, center gears, planetary gears and internal gears; the inner sides of the planetary gears are meshed with the center gears, the outer sides of the planetary gears are meshed with the internal gears, and the internal gears are meshed with the drive plate; the upper shaft sleeve is in interference fitting with the drive plate; a sealing cavity formed by connecting a brake wheel with a lower shaft sleeve is formed in the outside of the planetary gear train; the planetary gears are mounted on the lower shaft sleeve; an upper fixing ring convenient to connect is arranged on a lower casing, and the lower part of the upper fixing ring is connected with a lower fixing ring; a shift lever penetrates through the upper fixing ring and the lower fixing ring; a clutch sleeve is carried on the shift lever and glidingly mounted on the lower shaft sleeve through a spline; and a reset spring is arranged between the clutch sleeve and the lower shaft sleeve. The dual-power direct-drive clutch can reduce vibration and noises of the washing machine and can prolong the service life of the washing machine.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a direct-drive clutch of a dual-power washing machine. Background technique [0002] The existing dual-power direct drive clutch does not have a brake wheel, but only a set of planetary gear trains. The central gear is fixed on the output shaft, the planetary gears are fixed in the planet carrier, and the inner gear is connected to the output bushing. Its characteristic is that the planet carrier is The special shape is connected with the metal clutch sleeve through the spline, and the upper and lower sides of the clutch sleeve are distributed with teeth. When the electromagnetic coil is energized, the clutch sleeve moves upward under the action of the magnetic force, and its upper end teeth engage with the motor mounting plate. The clutch sleeve , The planetary carrier is locked, at this time the central gear and the internal gear rotate in reverse, and drive the pulsat...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage is that during dehydration, the dehydration bucket, the upper shaft sleeve, the input shaft and the motor rotor cannot be fixedly connected as a whole, and can only be connected by splines and gears with relatively large gaps. The high-speed rotating barrel completely depends on the motor mounting plate. One of the bearings is supported by a single fulcrum, and the rigidity is poor, which not only causes greater vibration and noise, but also affects the service life of the washing machine
