摘要/Abstract

摘要： 采用有限元仿真和试验方法分析贝氏体等温淬火工艺对GCr15钢轴承套圈畸变和断裂韧性的影响。采用Deform-3D软件对轴承套圈贝氏体淬火工艺进行数值模拟。以圆柱滚子轴承NJ308为研究对象,仿真热处理后最大直径畸变量为0.08 mm,与试验结果对比,仿真误差14%。采用热处理工艺试验,测量贝氏体淬火后轴承直径畸变量为0.07 mm。对比测量分析常规马氏体淬火和贝氏体淬火后的畸变大小,贝氏体热处理后直径畸变极差小,更为均匀,有利于后续的磨削加工。通过断裂试验对比分析,常规的马氏体淬回火工艺断裂强度为113.3 kN,贝氏体等温淬火处理后的断裂强度为152.7 kN,断裂强度显著提升。

Abstract: Effect of bainite isothermal quenching process on the distorsion and fracture toughness of GCr15 steel bearing rings was analyzed by using finite element simulation and experimental methods, where the numerical simulation of the bainite quenching process for bearing rings was carried out by using Deform-3D software. Taking cylindrical roller bearing NJ308 as the research object, the maximum distorsion after simulated heat treatment is 0.08 mm. Compared with the experimental results, the simulation error is 14%. Based on the bainite quenching process experiment, the distorsion of the bearing diameter is measured to be 0.07 mm, which is much smaller and more uniform than that after the conventional martensite quenching, and is beneficial for subsequent grinding processing. The fracture test results show that the fracture strength of the bearing rings after conventional martensite quenching and tempering process is 113.3 kN, while that after the bainite quenching treatment is significantly improved to 152.7 kN.
