根据摩擦学、传热学以及齿轮啮合原理等知识，确定了轮齿各表面的对流换热系数的计算方法，及啮合面摩擦热流密度的计算方法。利用AP DL语言建立了单齿热力耦合分析的有限元参数化模型。引进了混合介质特性参数的比例因子及修正系数，使得有限元模型更加接近实际工况。得到了齿轮单齿稳态温度场及热变形的有限元分析结果。并通过数据处理得到了啮合面热变形量沿啮合线法线方向的变形曲面。研究结果表明：齿轮的稳态温度场存在明显的温度梯度，啮合面温度最高，最高温度出现在啮出端双齿啮合区中部。齿轮的热变形存在明显的变形梯度，齿顶变形量最大，齿根最小。热变形沿啮合线法线方向的变形量，...

The convective heat transfer coefficient of different tooth surfaces and the friction heat flux density were identified based on the theory of tribology, heat transfer and gear meshing theory.The parametric model of finite element thermal analysis of single tooth was established by using APDL.The ratio factor and correction factor of mixed medium charac￣teristic parameters were proposed. The steady￣state temperature field and the thermal de￣formation of the single tooth were obtained. Through the data processing, the deformation surface alon...
