Clutch self-locking ratchet wheel and machining device thereof

Abstract

The invention discloses a clutch self-locking ratchet wheel and a machining device thereof, the clutch self-locking ratchet wheel comprises a shaft sleeve, a self-locking coil spring and a ratchet sleeve, convex ribs are arranged on the inner wall of the shaft sleeve, oil storage grooves are formed between the convex ribs, and ratchets are arranged on the outer wall of the ratchet sleeve; the self-locking coil spring is in clearance fit with the outer wall of the shaft sleeve, the ratchet sleeve is sleeved outside the shaft sleeve and the self-locking coil spring and is axially limited, the self-locking end of the self-locking coil spring is embedded into a snap spring groove in the inner wall of the ratchet sleeve, and the locking direction of the self-locking coil spring is consistent with the reverse rotation direction of the ratchet; the self-locking ratchet wheel has the advantages that the self-locking ratchet wheel is changed into an assembly structure and is divided into the shaft sleeve, the self-locking coil spring and the ratchet sleeve, namely, a self-locking structure is additionally arranged in the ratchet wheel, so that the ratchet sleeve and the shaft sleeve have a certain degree of freedom, the self-locking structure has a certain time interval from loosening to locking or from locking to loosening, a certain buffer time is provided for cutting-in or separation of the pawl, and the self-locking ratchet wheel is convenient to use. The collision strength of the pawl and the ratchets can be reduced, so that the reliability of the ratchet wheel and the pawl is enhanced, and the function switching stability of the washing machine is improved.

Description

technical field [0001] The invention belongs to the technical field of washing machine clutch parts and processing equipment thereof, and in particular relates to a clutch self-locking ratchet and a processing device thereof. Background technique [0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes, and it is used in every family. The washing machine uses a clutch to switch the washing and dehydration functions. The common dual-power washing machine uses a ratchet and a pawl to control the state of the clutch. After the pawl cuts into the ratchet, the clutch is in a disengaged state. When the ratchet and the ratchet are disengaged, the clutch is closed, and the transmission shaft makes the dehydration shaft and the washing shaft rotate synchronously through the clutch, which is the dehydration function. Among them, when the pawl cuts into or disengages from the ratchet wheel, it will collide with the ra...

AI Technical Summary

Problems solved by technology

Among them, when the pawl cuts into or disengages from the ratchet wheel, it will collide with the ratchet teeth on the ratchet wheel. If the strength of the ratchet or pawl is not strong enough, it will break and break, resulting in switching failure. That is, the reliability of the ratchet wheel and pawl determines the function of the washing machine. How to reduce the collision strength between pawl and ratchet has become a technical problem that those skilled in the art need to solve urgently.
