A dual-power washing machine direct-drive clutch

Abstract

The invention relates to the technical field of washing machines, and relates to the technical field of washing machines. It mainly includes an upper shaft sleeve and a planetary gear train. The planetary gear train is provided with a transmission disc, a central gear, a planetary gear and an internal gear. The planetary gears are The inner side is meshed with the central gear, the outer side is meshed with the inner gear, the inner gear is meshed with the transmission disc, the upper bushing is in interference connection with the transmission disc, and the outer surface of the planetary gear train is equipped with brake wheels and The lower shaft sleeves are connected to form a sealed cavity. The planetary gear is installed on the lower shaft sleeve. The lower housing is provided with an upper fixing ring for easy connection. The upper fixing ring is connected with the lower fixing ring, and the upper fixing ring A driving lever is threaded between the ring and the lower fixed ring, 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, and the clutch sleeve and the lower shaft sleeve are provided There is a return spring, which can not only reduce the vibration and noise of the washing machine, but also increase 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...

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
