Manufacturing method for improving performance of overrunning clutch

Abstract

The invention relates to a manufacturing method for improving the performance of an overrunning clutch. The overrunning clutch is provided with an inner ring and an outer ring, the inner ring and theouter ring are made of two different materials, the inner ring is provided with duplex metal loops with an outer loop and an inner loop, and the outer ring is provided with double loops with an outerloop and an inner loop. The outer loop of the outer ring is made of a material with high strength and good plasticity, and the inner loop of the outer ring is made of a metal material with high hardness. The outer loop of the inner ring is made of a metal material with high hardness, and the inner loop of the inner ring is made of a metal material with high strength and good plasticity. The innerloops and the outer loops are in interference fit to transfer torque. When the overrunning clutch is installed, the outer ring is arranged on the outer periphery of the inner ring in a sleeving manner, balls are arranged between the inner ring and the outer ring, and the balls are in contact with the inner wall of the outer ring. By means of the manufacturing method, two kinds of materials with high hardness and high strength and good plasticity are adopted to manufacture the inner ring and the outer ring of the overrunning clutch, and the performance of the overrunning clutch is improved.

Description

technical field [0001] The invention belongs to the class of electromechanical devices, in particular to an overrunning clutch widely used in mechanical engineering and a manufacturing method capable of improving the performance of the overrunning clutch. Background technique [0002] Overrunning clutch is a kind of clutch widely used in mechanical engineering. The overrunning clutch runs smoothly, and at any speed, as long as there is a speed difference between the main and driven parts, it can be automatically engaged, and the response is very sensitive, so it is a clutch with very good performance. [0003] The overrunning clutch transmits torque through the self-locking effect between the ball and the inner and outer rings. Its force characteristic is that the positive pressure between the ball and the inner and outer rings is very large, so the force on the inner and outer rings and the contact stress between the balls and the inner and outer rings are very large, whic...

AI Technical Summary

Problems solved by technology

At present, the inner and outer rings of the overrunning clutch are made of the same material, which often cannot meet the above two requirements at the same time.
