Direct-drive clutch of washing machine

Abstract

The invention discloses a direct-drive clutch of a washing machine, and relates to the technical field of washing machines. The direct-drive clutch comprises an upper shaft sleeve and a planetary gear train, wherein a planet carrier, an input shaft gear, a planetary gear and an internal gear are arranged in the planetary gear train; the inner side of the planetary gear is meshed with the input shaft gear, and the outer side of the planetary gear is meshed with the internal gear; a seal cavity formed by connecting a brake wheel and a lower shaft sleeve is arranged outside the planetary gear train; the internal gear is mounted on the lower shaft sleeve; the upper shaft sleeve is in interference joint with the brake wheel; an upper fixing ring which can be connected conveniently is arranged on the lower shaft sleeve; a lower fixing ring is connected to the lower part of the upper fixing ring; a shift lever penetrates through the upper fixing ring and the lower fixing ring; a clutch sleeve is supported on the shift lever and glidingly mounted on the lower shaft sleeve through a spline; and a reset spring is mounted between the clutch sleeve and the lower shaft sleeve, so that not only can vibration and noise of the washing machine be reduced, but also the service life of the washing machine can be prolonged.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a direct drive clutch of the washing machine. Background technique [0002] The existing ordinary washing machine direct drive clutch does not have a brake wheel, only a set of planetary gear train, the input shaft gear is fixed on the output shaft, the planetary gear is fixed in the planet carrier, and is connected with the metal clutch sleeve by a spline, and the clutch sleeve There are claws distributed up and down. 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. When the electromagnetic coil is powered off, the clutch sleeve moves downward under the action of gravity, and its upper end The tooth insert is disengaged from the motor mounting plate, and the lower end tooth insert is engaged with the motor rotor to connect the clutch sleeve, th...

AI Technical Summary

Problems solved by technology

[0003] 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
