Problems solved by technology
[0002] The shaft sleeve is a common part in mechanical design, especially in the clutch. In order to position and protect the pulsator, the shaft sleeve is set outside the rotating shaft to protect the rotating shaft. The outer end of the shaft sleeve is usually tightened with the connecting piece. It is fixed by fit or by splines, but when the sleeve is worn out and needs to be removed and replaced, it is very inconvenient, and it is easy to scratch the connecting piece, shortening the service life of the connecting piece
In addition, due to the continuous friction between the shaft and the sleeve, the shaft and the sleeve need to be fully lubricated, otherwise the wear rate will be fast and the service life will be relatively short, but lubricating oil needs to be added to the internal contact surface between the shaft and the sleeve On the other hand, it is necessary to separate the shaft and the sleeve before adding it, which makes the operation complicated and the efficiency low

The invention discloses an impeller shaft sleeve for a clutch. The impeller shaft sleeve comprises a hollow circular column shaft sleeve body, beads are arranged on the shaft sleeve body, the two ends of each bead extend to the two end faces of the shaft sleeve body in the axial direction, and a check ring is arranged on one end face of the shaft sleeve body. The beads and the check ring are arranged on the outer wall of the shaft sleeve, the shaft sleeve is precisely matched with a connecting piece, vibration and noise are reduced, the shaft sleeve can be conveniently dismounted, and other parts cannot be damaged. Through other improvements, the abrasion resistance of the shaft sleeve is improved, meanwhile, a shaft and the shaft sleeve are prevented from being dismounted, the cost is saved, and the effect is improved.
