AI Technical Summary

Technical Problem

The existing overpass clutch has the risk of reversal after overpass, and the structure is complex and the manufacturing cost is high, making it difficult to meet the small torque requirements of simple structure, low manufacturing cost and smooth combination.

Method used

A anti-reversal conical disc friction overpass clutch is designed, and a combined structure of a reverse stop cone sleeve and a drive cone sleeve are adopted. Through the cooperation of the cylindrical pin and the torsion spring, the reverse stop and drive functions of the driving shaft are realized to avoid reversal.

Benefits of technology

It achieves a small torque with simple structure, low manufacturing cost and smooth combination, avoids the risk of reversal, is suitable for small space occasions, and is easy to replace and maintain.

Abstract

The invention provides an anti-reversion cone disc friction type overrun clutch. The anti-reversion conical disc friction type overrun clutch comprises a shaft check ring, a hole check ring, a fixing ring, a bearing, a non-return conical sleeve, a cylindrical pin, a torsion spring, a driving conical sleeve, a driven ring and a driving shaft, the non-return conical sleeve is arranged between the fixing ring and the driving shaft, and the driving conical sleeve is arranged between the driven ring and the driving shaft. Two cylindrical pins are arranged among the non-return conical sleeve, the driving conical sleeve and the driving shaft, and a torsional spring is arranged between the non-return conical sleeve and the driving conical sleeve. The anti-reversion cone disc friction type overrun clutch has the advantages of being simple and compact in structure, easy to manufacture, convenient to install, low in production cost, large in torque density, small in noise and abrasion in use, long in service life, more suitable for small-space occasions, easier to replace and maintain and capable of achieving product serialization.
