摘要
齿面温度及其变化是计算轮齿变形和判断齿轮是否胶合的主要依据。根据面齿轮传动以及传热学的基本原理,通过对面齿轮啮合接触区进行分析,运用表面温度法,介绍了面齿轮点接触区润滑数学模型、油膜厚度方程和油膜能量方程,建立了面齿轮传动的齿面瞬时接触温度的计算方程。研究了啮合齿面间的接触应力、齿面相对滑动速度以及齿面间的摩擦系数等相关参数的计算。对面齿轮传动的啮合过程中不同啮合位置时,齿面温升进行有限元分析,研究面齿轮齿面温度的分布规律,为面齿轮的设计提供有效的理论依据。
Tooth surface temperature and its changes are main basis to calculate gear tooth deformation and to determine whether gluing or not. According to the basic principles of face-gear driving and heat transfer, analyzed the face gear meshing area. By means of surface temperature method, derived face-gear mathematical model of lubrication, oil film thickness equation and oil film energy equation, and established the face-gear transmission equations for calculating instantaneous contact temperature. Studied the contact stress of engagement, relative sliding velocity of tooth surface and the computing of friction coefficient between the tooth surface. Conducted a finite element analysis on the temperature rise at different positions in the face-gear meshing process. Researched the tooth surface temperature distribution to provide an effective theoretical basis for face-gear design.
