Abstract

This work studied the effect of temperature on gear stiffness in the full temperature range which contained thermal expansion and cold shrinkage. Considering the temperature effect, a meshing stiffness model for spur gear pairs in the full temperature range was established based on the conservation of energy. The general calculation formula for the gear pair’s temperature meshing stiffness in the full temperature range was derived. The influence of addendum modification and gear temperature distribution on gear stiffness was studied. Thereafter, the proposed model was verified experimentally. The results revealed that the temperature stiffness was smaller than the standard stiffness of the gears in the full temperature range. When the temperature of the gears increased from an initial temperature, which was lower than the standard temperature, the temperature stiffness of the gear first increased and then decreased. Moreover, the obtained results could provide theoretical support for an accurate dynamic analysis of gear transmission systems in the full temperature range.
考虑温度效应的正齿轮副啮合刚度模型
在包含热膨胀和冷缩的全温度范围内,研究了温度对齿轮刚度的影响。考虑温度效应,建立了基于能量守恒的全温度范围内直齿轮副啮合刚度模型。推导了全温度范围内齿轮副温度啮合刚度的一般计算公式。研究了齿顶修形和齿轮温度分布对齿轮刚度的影响。随后,对该模型进行了实验验证。结果表明,在整个温度范围内,齿轮的温度刚度小于标准刚度。当齿轮温度从低于标准温度的初始温度开始升高时,齿轮的温度刚度先增大后减小。所得结果可为齿轮传动系统在全温度范围内的精确动力学分析提供理论支持。
