Abstract

Article history Received: 4 June 2019 Accepted: 12 August 2019 Published Online: 30 November 2019 The thermal balance state of high-speed and heavy-load gear transmission system has an important influence on the performance and failure of gear transmission and the design of gear lubrication system. Excessive surface temperature of gear teeth is the main cause of gluing failure of gear contact surface. To investigate the gear heat distribution in meshing process and discuss the effect of thermal conduction on heat distribution,a finite element model of spur gear is presented in the paper which can represent general involute spur gears. And a simulation approach is use to calculate gear heat distribution in meshing process. By comparing with theoretical calculation, the correctness of the simulation method is verified, and the heat distribution of spur gear under the condition of heat conduction is further analyzed. The difference between the calculation results with heat conduction and without heat conduction is compared. The research has certain reference significance for dry gear hobbing and the same type of thermal-structural coupling analysis.

基于热结构耦合的齿轮啮合过程热分布数值模拟

文章历史收稿日期:2019年6月4日接收日期:2019年8月12日发布在线日期:2019年11月30日高速重载齿轮传动系统的热平衡状态对齿轮传动的性能和故障以及齿轮润滑系统的设计有重要影响。齿轮齿面温度过高是造成齿轮接触面粘接失效的主要原因。为了研究齿轮在啮合过程中的热分布，探讨热传导对热分布的影响，建立了能代表一般渐开线直齿齿轮的有限元模型。并采用仿真方法计算了齿轮啮合过程中的热分布。通过与理论计算的比较，验证了仿真方法的正确性，并进一步分析了热传导条件下直齿齿轮的热量分布。比较了有导热与无导热计算结果的差异。该研究对干式滚齿加工及同类热-结构耦合分析具有一定的参考意义。
