Problems solved by technology

[0005] However, during the washing process of the washing machine with the above-mentioned deceleration clutch, the inner tub and the pulsator frequently rotate in the opposite direction, and the inertia moment generated by the inner tub directly acts on the overrunning clutch. quality problem
During the rotation of the inner tub, there will often be a reaction force on the lower one-way bearing, and the one-way bearing is prone to failure. At the same time, the clutch spring will be tightly held during washing, resulting in damage to the clutch spring.
In addition, because the dehydration shaft is separated from the brake wheel and is connected with the deceleration clutch, the inner tub has a slight swing in the dehydration state, which directly acts on the dehydration shaft, and the bearing support of the dehydration shaft is relatively eccentric, resulting in one end of the dehydration shaft. When the torque is large, it will increase the vibration of the washing machine and cause noise

Embodiment 1

[0066] Such as Figure 8 As shown, the difference between this embodiment and the above-mentioned specific embodiments is only that: the upper planetary carrier 7 and the lower ring gear 6 of this embodiment are fixedly connected by means of hole pin assembly.

[0067] A plurality of first fixed pins 706 are arranged along the circumferential direction on the end of the upper planetary carrier seat 704 of the upper planetary carrier 7 near the end of the lower gear train in this embodiment, and the lower inner ring gear 6 is close to the upper gear train A plurality of first installation holes 603 are provided on the end of one end corresponding to the first fixing pins 706 , and the first fixing pins 706 are inserted into the first installation holes 603 to realize a fixed connection in the way of hole pin assembly.

[0068] Further, the upper planetary gear carrier 7 is fixedly connected to the lower ring gear 6 through key connection or hole pin assembly.

[0069] The firs...

Embodiment 2

[0074] The difference between this embodiment and the above specific implementation is only that the lower ring gear connection part 602 is the inner tooth of the lower ring gear 6, and the connecting key on the upper planetary gear carrier 7 is the inner tooth of the lower ring gear. The inner teeth of the ring 6 mesh with the outer teeth, and the upper planetary carrier 7 at the end of the outer teeth is provided with a convex step for limiting the axial displacement of the upper planetary carrier 7 .

[0075] The advantage of adopting this method is that the structure of the lower inner ring gear 6 remains unchanged, and there is no need to separately process splines or open installation holes on the lower inner ring gear 6, and set the upper planetary gear carrier 7 with the lower inner ring gear. The outer teeth of the ring gear 6 have the same tooth shape. After meshing the outer teeth of the upper planetary gear carrier 7 with the inner teeth of the lower inner ring gear...

Embodiment 3

[0077] Such as Figure 9 , Figure 10 , Figure 11 The dehydration shaft of the washing machine in this embodiment includes a shaft body 1201 and a shaft seat 1202, the upper end of the shaft body 1201 is fixedly connected to the washing tub of the washing machine, and the lower end of the shaft body 1201 is fixedly connected to the shaft body 1202 or the shaft body 1201 The lower end is integrally formed with the shaft seat 1202; the dehydration shaft is connected with the reducer of the washing machine through the shaft seat; the shaft body is provided with a shaft through hole 1203 for the output shaft 13 to pass through.

[0078] Since the brake wheel 11 of the deceleration clutch of the present invention is fixedly connected to the dehydration shaft, this embodiment provides a dehydration shaft with a brand new structure, which consists of two parts, the shaft body 1201 and the shaft seat 1202, which are integrally formed or fixedly connected separately. Composition, th...

Abstract

The invention provides a washing machine speed reduction clutch which comprises a braking wheel and a double-layer planetary gear train arranged in the braking wheel. A lower gear train of the double-layer planetary gear train comprises a lower center gear, a lower planet gear meshed with the lower center gear, a lower planet carrier and a lower internal gear ring. The lower center gear is fixedly connected with an input shaft. The lower planet gear is meshed with the lower internal gear ring. The lower portion of the lower internal gear ring is fixedly connected with an input shaft sleeve. An upper gear train of the double-layer planetary gear train comprises an upper center gear, an upper planet gear meshed with the upper center gear, an upper planet carrier and an upper internal gear ring. The upper center gear is connected with an output shaft. The upper planet gear is meshed with the upper internal gear ring. The periphery of the upper internal gear ring is fixedly connected with the braking wheel. The lower planet carrier is fixedly connected with the upper center gear. The upper planet carrier is fixedly connected with the lower internal gear ring. According to the specific structure of the washing machine speed reduction clutch, transmission is stable and reliable, and the whole structural strength is higher.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine deceleration clutch and a washing machine. Background technique [0002] Dual-power washing machine is a new type of pulsator washing machine. Its main feature is that when washing, the inner tub and the pulsator of the washing machine will rotate in opposite directions and at different speeds, so that the laundry will be swayed by the inner tub during the washing process. And the reverse rotation force of the pulsator plays the role of rubbing and washing the laundry, and the washing cleanliness is higher. [0003] When the washing machine is washing, the reverse rotation of the inner tub and the pulsator is mainly realized by the deceleration clutch of the washing machine. The existing two-way drive deceleration clutch of the washing machine generally adopts a planetary fixed shaft gear train transmission structure, a gear transmission mechanism and a...
