Washing machine deceleration clutch ratchet and clutch device

Abstract

The invention provides a ratchet wheel of a speed reduction clutch of a washing machine and a clutch device, comprising the ratchet wheel, of the speed reduction clutch. The clutch device comprises a clutch spring and the ratchet wheel. The tail end of the clutch spring extends outwards to form a clamping end. The ratchet wheel comprises a ratchet wheel body and a plurality of ratchet wheel teeth formed on the outer wall of the ratchet wheel body in the circumferential direction. An installation cavity with openings in the upper portion and the lower portion is defined by the inner wall of the ratchet wheel body. The inner wall of the ratchet wheel body is connected with the outer wall of the ratchet wheel body through a plurality of reinforcing walls. A clamping groove is formed in the inner wall of the ratchet wheel body, and the clamping end of the clutch spring is suitable for being installed in the clamping groove. The clamping groove comprises a guide section, a transverse section and a clamping section. The guide section extends from the lower end of the ratchet wheel body upwards, the transverse section transversely extends along the inner wall of the ratchet wheel body from the upper end of the guide section, and the clamping section extends from the tail end of the transverse section downwards.

Description

technical field [0001] The invention relates to the field of washing machine deceleration clutches, in particular to a ratchet used on the washing machine deceleration clutch and a clutch device comprising the ratchet. Background technique [0002] The full-automatic pulsator washing machines sold on the existing market are all provided with deceleration clutches, which are used as transmission parts to reduce the rotating speed of the motor and increase the torque to drive the pulsator to work. The clutch device generally includes a ratchet, a pawl and a clutch spring, and the clutch spring is clamped in the ratchet. The common faults caused by the clutch device of the deceleration clutch are: 1. The one-way rotation of the pulsator caused by the lack of oil or deformation of the clutch spring, and the fault of washing friction noise; 2. The fault of non-drying caused by the breakage of the clutch spring. The clutch spring must be taken out from the ratchet when oil needs ...

AI Technical Summary

Problems solved by technology

The common faults caused by the clutch device of the deceleration clutch are: 1. The one-way rotation of the pulsator caused by the lack of oil or deformation of the clutch spring, and the fault of washing friction noise; 2. The fault of non-drying caused by the breakage of the clutch spring

When it is necessary to add oil or replace the clutch spring, the clutch spring must be taken out from the ratchet. Most of the existing clutch springs are directly locked in the slot of the ratchet through the spring clips arranged at the bottom, which is very inconvenient to replace.
