A washing machine direct drive clutch

Abstract

The invention relates to a washing machine direct-drive clutch, which relates to the technical field of washing machines. It includes an upper shaft sleeve and a planetary gear train. The planetary gear train is provided with a planet carrier, an input shaft gear, a planetary gear and an internal gear. The planetary gear The inner side of the planetary gear meshes with the input shaft gear, and the outer side meshes with the internal gear. The outer surface of the planetary gear train is provided with a sealed cavity composed of the brake wheel and the lower bushing. The inner gear is installed on the lower bushing. The upper and upper shaft sleeves are in interference connection with the brake wheel; the lower housing is provided with an upper fixing ring for easy connection, and the upper fixing ring is connected with the lower fixing ring, and the upper fixing ring and the lower fixing ring are passed through There is a driving lever, and a clutch sleeve is supported on the driving lever, and the clutch sleeve is slidably installed on the lower shaft sleeve through a spline. A return spring is arranged between the clutch sleeve and the lower shaft sleeve, which not only reduces the The vibration and noise of the washing machine can be reduced, and the service life of the washing machine can be improved.

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...

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
