不同磨削工况下成形磨齿温度梯度的研究

Research on Shaping Grinding Temperature Gradient Under Different Grinding Condition

基于有限元分析理论,对干磨和湿磨两种磨削工况下的成形磨齿温度梯度进行了瞬态分析,并讨论了磨削区某一节点处干磨和湿磨温度梯度随时间的变化情况。研究表明,磨齿加工过程中,无论是干磨还是湿磨,在磨削初始阶段,齿面上的温度梯度不大,在磨削结束阶段,温度梯度值最大。由于磨削液的作用,湿磨温度梯度变化比干磨温度梯度变化小。

Based on the theory of finite element analysis,Analyze grinding temperature gradien og two kinds of grinding conditions,the dry milling and wet milling,in transient analysist,and discusses the gradient changes in a node in the grinding zone between dry milling and wet milling temperature over time.Studies have shown that in the process of gear grinding processing, no matter the dry milling or the wet milling,in the initial stage,the grinding temperature gradient on the surface of the tooth is small,at the end of the grinding temperature gradient value became maximum.Because of the effect of grinding fluid,wet milling is smaller than dry grinding in the temperature gradient change.
