摘要

以渐开线直齿圆柱齿轮副为研究对象,基于改进的摩擦热量离心抛射扩散模型计算齿面对流换热系数,综合有限元仿真及摩擦生热分析求得齿面热流量,计算了考虑轴线平行度误差的齿轮副本体温度,进而建立热-结构耦合分析模型,研究轴线平行度误差、温度影响下齿轮副的修形量,给出了确定合理齿廓及齿向修形量的方法。结果表明,温度对修形量有一定影响,轴线平行度误差使得齿轮副齿向两端啮入/啮出干涉量不同,存在偏载的齿轮副应按齿廓齿向综合修形方式对齿轮副修形。

Abstract

Taking the involute spur gear pair as the research object,the tooth surface convection heat transfer equation is obtained based on the improved friction heat spread by centrifugal ejection model,the tooth surface heat flow equation is obtained based on finite element method and friction heat analysis,on this basis,the gear pair bulk temperature is analyzed considering axis parallelism deviation. Then,thermal- structural coupled model is established,thus gear modification amount is analyzed under axis parallelism deviation and gear pair bulk temperature. After that,the method of calculating appropriate amount of modification is obtained. The result shows that the modification amount can be affected by temperature,and axis parallelism deviation may cause different axial mesh in / mesh out interference,gear pair with axis parallelism deviation is suggested to use profile and axial modification.
