Spring leaf and overrunning clutch mounted with spring leafs

Abstract

The invention relates to a spring leaf and an overrunning clutch mounted with the spring leafs, the spring leaf is composed of a support piece supporting the suspension of roller pins, a clamping piece and a connection beam connecting the support piece and the clamping piece, wherein the body of the clamping piece is a straight piece with two ends provided with V-shaped bending portions. The overrunning clutch includes a retaining rack, a plurality of roller pins and a plurality of spring leafs, wherein spring leaf installation grooves are respectively arranged at positions, corresponding to the beams, of outer end faces of first and second annular end edges at both ends of an aperture on the retaining rack, the bottoms of the spring leaf installation grooves form into the shape of V by sectioning in the axial direction of the retaining rack; the inner surface of the straight piece of the clamping piece of the spring leaf is adhered to the outer surface of the cross beam, and the inner surfaces of the V-shaped bending portions of the clamping piece are matched with the bottom surfaces of the spring leaf installation grooves. The overrunning clutch mounted with the spring leafs solves the technical problem regarding the hidden danger of displacement and disengagement of the spring during the reciprocating movement of the current overrunning clutch at high rotating speed and high frequency.

Description

technical field [0001] The invention relates to a spring leaf and an overrunning clutch equipped with the spring leaf. Background technique [0002] The overrunning clutch is a clutch that can be automatically engaged or disengaged by the change of the relative motion speed of the main and driven parts or the change of the direction of rotation; it is the basic element in the mechanical transmission of electromechanical integration, and its main function is to prevent reverse rotation, precise positioning, transmission Torque, or cut-off torque, so it is also called backstop or one-way bearing, which is widely used in machine tools, packaging machinery, printing machinery, light industrial machinery, textile machinery, petrochemical machinery, cement machinery, metallurgical machinery, transportation machinery , reducer, etc. There are many types of overrunning clutches, commonly used are pawl type overrunning clutches, needle roller overrunning clutches and wedge type over...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to solve the technical problem that the spring leaf of the existing overrunning clutch has a hidden danger of displacement and falling off at high speed. The present invention provides a spring leaf and an overrunning clutch equipped with the spring leaf. After the cage is matched, it can be fixed on the cage stably and reliably, ensuring continuous and stable operation of the overrunning clutch
