Abstract：

For the driven plate of clutch, the relationship between the diameter of driven plate and the amount of deformation after quenching was analyzed. Then, the deformations of driven plates with different diameters after quenching appeared hyperbolic parabolic shape, and the deformation increased with the increase of diameter in the driven plate. Furthermore, the temperature field of driven plate in quenching was simulated by the finite element software ANSYS, and the direct cause of the quenching deformation was the uneven distribution of temperature field produced by “L” structure of limit spring window. In addition, the deformation process of carbonitriding and quenching was optimized and the experiment was carried out to verify the optimized technology. The results show that the maximum deformation of driven plate reduces from 5.7 mm to 1.1 mm after optimization by the optimized technology of open transition circular hole in window, open auxiliary hole, low quenching temperature and high temperature of oil. Based on the above conclusion, it can be a better guidance in the practical production of enterprises.
