20CrMnTi材料成分波动对齿轮渗碳淬火性能的影响
Effect of 20CrMnTi material compositions fluctuation on gear performance after carburizing and quenching process
摘要
Abstract
The discussion about the effect of 20CrMnTi material compositions fluctuation on gear carburizing-quenching performance was done using FEM.Taking 20CrMnTi side gear as the research object,two groups of material properties databases were set up according to the maximum and the minimum values of chemical elements fluctuation by JMATPRO software.Simulation mathematical model was built for carburizing-quenching process based on DEFORM-HT software.Some simulations were done for gear carburizing-quenching process with two material databases.Simulation resuhs were compared.The results show that material compositions fluctuation has little impact on carburized layer,and has great impact on distribution of quenching phases and deformation of gear.关键词
