摘要
以22CrMo材料锥齿轮为研究对象,通过有限元方法,研究了材料成分波动对锥齿轮渗碳淬火性能的影响。利用材料数据库软件,基于22CrMo材料元素范围的上、下限建立2组材料性能数据库;利用热处理仿真软件建立模型,并对2组材料成分的被动锥齿轮进行渗碳淬火仿真,对比分析了锥齿轮渗碳淬火后表层碳浓度、微观组织演化及齿轮变形等数据。结果表明,材料成分波动对22CrMo锥齿轮淬火后的相组织分布以及齿轮变形量影响较大,对渗碳层影响较小。
Taking 22CrMo material passive bevel gear of drive axle as the research object,this paper studies the influence of material composition fluctuation on carburizing and quenching characteristics of bevel gear by finite element method.Based on the upper and lower limits of the fluctuation range of the material elements,two groups of material property databases are established using material database software.The heat treatment simulation software is used to establish a model to simulate the carburizing and quenching process of 2 groups of passive bevel gears,and the surface carbon concentration,microstructure evolution and gear deformation of bevel gears are compared and analyzed.The results show that the material composition fluctuation has great influence on the phase structure distribution and gear deformation of 22CrMo bevel gear after quenching,but has little influence on carburizing layer.
