极端环境下滤波齿轮传动侧隙分析

Analysis of Filter Gear Transmission Backlash in the Extreme Environment

用于航空航天的滤波齿轮传动的啮合侧隙必定会受到其极端环境的影响,而传动侧隙的大小又是影响齿轮工作性能的重要因素之一。根据热平衡和传热学的基本理论,基于ANSYS Workbench仿真软件模拟出了齿轮啮合区的温度。分析齿轮热变形和箱体热变形对传动侧隙的影响,求得齿轮在极端环境下工作的最小侧隙,得出其随环境温度变化的规律。为其未来在航空航天的应用提供了理论依据。

The backlash of the filter gear using for aerospace can be influenced by the extreme environment, and the size of the backlash is one of the most important factors that influence gear transmission accuracy. Based on the thermal equilibrium and heat transfer theory, the temperature of the meshing zone is simulated with ANSYS Work- bench. The influence of thermal deformation of both gear and box on transmission backlash is studied, and the changing regularity of the minimum backlash under different temperatures is obtained. The theoretic basis for aerospace applica- tion of the filtering gear reducer is provided by this study.
