摘要: 喷油润滑的设计直接影响齿面润滑油膜分布，而齿面润滑油膜沉积铺展分析是喷油润滑设计的重要内容。本文基于计算流体动力学方法建立了人字齿轮的喷油润滑分析模型，计算了在不同啮合角度下特征齿面的油膜沉积铺展情况。结果表明：特征齿面上位于喷油口下方的区域润滑油的体积比较高，油膜厚度也较大；润滑油喷到特征齿面的油路受到周围轮齿的干涉后齿面润滑油的体积比出现明显下降；不同啮合角度下铺展形成齿面润滑油膜的分布和面积存在一定差异；啮合轮齿处于1.5°啮合角度时，啮入侧两个喷油口才会同时喷射润滑油到同一齿面，此时润滑油膜的面积较大。Abstract: The design of spray lubrication has an important influence on the oil film distribution of teeth surface, and the study on spraying oil and oil film spreading is also significant for designing the spray lubrication. A numerical model is developed based on the Computational Fluid Dynamics method to calculate the spreading characteristics of oil film on teeth surface. The results indicated that the region of characteristic tooth under the spray nozzle has more oil. The oil reduces when the oil stream between the spray nozzle and the characteristic tooth surface is blocked. The distribution of oil film in characteristic tooth surface is obviously different when the meshing angle is changed. Two nozzles spray the oil on the same tooth surface when meshing angle is 1.5°.
