摘　　要：首先对整个减速器进行热分析,得到减速器的整体温度场分布。然后再根据减速器箱体所承受静载荷及减温度场分布分析结果对减速器箱体进行热-结构耦合及热-结构加载耦合特性分析。研究结果表明,箱体受到的机械载荷对箱体的最大应力影响较大,而箱体的温度场分布对减速器箱体的最大变形量影响较大。Firstly, the whole temperature field distribution of reducer is achieved by analyzing the thermal characteristic of the whole reducer. Then, according to the result of temperature field distribu- tion and the static load on the reducer, the characteristic analysis of thermal--structure coupling and thermal--structure loading coupling of the reducer box is carried out. The result shows that, the me- chanical load applied on the gearbox has a great influence on the maximum stress of gearbox, and the temperature field distribution has a great effect on the maximum deformation of gearbox.
