Rubber ring and ball type one-way clutch

Abstract

The invention discloses a rubber ring and ball type one-way clutch. The rubber ring and ball type one-way clutch comprises a shell, a driving wheel and a pinion, wherein the driving wheel and the pinion are arranged inside the shell; a rectangular groove is formed in the outer side surface of the pinion, and a rubber ring is arranged inside the rectangular groove; a plurality of balls are arranged between the driving wheel and the pinion, ball slide ways with the number corresponding to the number of the balls are formed in the inner side surface of the driving wheel, and stop blocks are arranged at the tail ends of the ball slide ways; when the pinion rotates forward, the balls act on the rubber ring and slide to the tail ends of the ball slide ways for locking the pinion. According to the rubber ring and ball type one-way clutch, the rectangular groove is formed in the pinion, the rubber ring is arranged in a sleeved mode and replaces a spring, pressure of the spring is avoided when the pinion rotates reversely, and the balls do not make contact with the pinion, can rotate flexibly and are free of eccentric wear. The rubber ring and ball type one-way clutch has the advantages that manufacturing and machining are simple, the quality is easy to control, the structure is reasonable and the service life is long. Resistance is avoided in the reverse rotation process, a starter is effectively protected, and the phenomena of gear impacting and gear pushing are avoided obviously.

Description

【Technical field】 [0001] The invention belongs to the field of mechanical manufacturing, and relates to a one-way clutch, in particular to a rubber ring ball type one-way clutch. 【Background technique】 [0002] like figure 1 As shown, the most common starter one-way clutch is the spring ball one-way clutch. Its disadvantages are: the spring force is large, and the balls are not flexible when the pinion is reversed, causing the balls to be eccentrically worn. Springs are prone to fatigue, wear out, and crush. In addition, although it can rotate in reverse, there is still a lot of resistance when it is reversed, and the starter will still be rotated, and it will burn out in severe cases. Finally, the spring ball type one-way clutch, because of the pressure of the spring, the pinion gear cannot move freely. At the moment of coupling, without flexibility, it is not easy to combine with the flywheel ring gear, and it is easy to have teeth hitting and top teeth. 【Content of in...

AI Technical Summary

Problems solved by technology

[0002] like figure 1 As shown, the most common type of starter one-way clutch is the spring ball one-way clutch. Its disadvantages are: the spring force is large, and the balls are not flexible when the pinion is reversed, causing the balls to be eccentrically worn.

The spring is easy to fatigue, easy to wear, easy to be crushed

In addition, although it can rotate in the reverse direction, there is still a lot of resistance when it is reversed, and the starter will still be rotated, and it will burn out if it is serious.

Finally, the spring ball type one-way clutch, because of the pressure of the spring, the pinion cannot move freely. At the moment of combination, there is no flexibility, so it is not easy to combine with the flywheel ring gear, and it is easy to have teeth and top teeth
