A V-pulley manufacturing process, comprising the following steps: forming a pulley by integrally forming a cylindrical pulley blank (1); machining a V-shaped belt groove, cutting the external surface of the pulley blank to form a plurality of V-shaped belt grooves (2) matching the V belt; fine machining, cutting the external surface of the pulley blank and the side surfaces of the belt grooves, cutting off the machining allowance; shot blasting, placing the pulley in a shot blasting machine to form a rough shot blasting layer (3) on the side surfaces of the belt grooves. The pulley manufactured by the above process has a great friction coefficient of the side surfaces of the belt grooves, thus is unlikely to slip, and provides high drive efficiency. |
