CN-224201071-U - Synchronous wheel formed by stamping

Abstract

The utility model discloses a stamping forming synchronous wheel, and relates to the technical field of transmission components. Including annular support plate, a plurality of equidistant amortization grooves have been offered in the annular support plate top penetration, the backup pad inner wall has a plurality of equidistant strengthening ribs of two along radial inboard fixedly connected with at least, strengthening rib one side fixedly connected with go-between. According to the utility model, through the arrangement of the supporting mechanism and the heat dissipation mechanism, in the use process, the power shaft passes through the clamping boss and is fixed, then the power shaft drives the teeth to rotate to drive the engaged parts to move so as to realize power transmission, in the rotation process, the main load is borne by the annular supporting plate and is dispersed by the reinforcing ribs, then the teeth of the wear-resisting plate are contacted with the matching piece, so that the abrasion is reduced, and meanwhile, the heat dissipation holes and the heat dissipation grooves accelerate the air flow.
