Abstract

PURPOSE: To manufacture single-V groove pulley at a low production cost, by carrying out cutting processing of V groove on the circumference face after carrying out cold press processing of the material obtained by cutting a round bar metal material in a fixed length and forming the original form of pulley.
CONSTITUTION: The outer original form 3 of pulley is formed by carrying out cold press processing of the material obtained by cutting a round bar steel in a fixed length. The boss part 4 of the form 3 is formed at the central part and the arm 5 is continued to the part 4 and moreover,is continued to the flange part 7. The slope 7, 8 made parallel to the side face of V groove cutting afterwards, are formed on both sides of the arm 5. The slope 7,8 are necessary to heighten the coefficient of utilization of the material and moreover, is hardened by carrying out plastic processing from the material is selected so as its volume to be the same to that of the from and its strength is increased. Cubic volume of the material is selected so as its volume to be the same to that of the form 3 before punching the preforation having the diameter d of the part 4. Next, the V groove 9 having the same angle of inclination to the slope 7, 8 of the arm 5 on the outer circumference face of the flange part 6 of the form 3, is cut and the V groove pulley is finished.
