四、齿面瞬时接触温度与滑油特征退吸温度由上述可知,齿面处于弹塑性混合接触状态与微润滑的混合润滑状态,则必须对与擦伤密切相关的齿面温度进行分析,首先对轮齿表面接触温升进行分析,特别是滑动速度较高的啮合始点与啮合终点,齿面接触温升也就是轮齿接触中赫兹宏观面积上的瞬时 Fourth, the instantaneous contact temperature of the tooth surface and the characteristics of the oil aspiration temperature From the above we can see that the tooth surface is in a state of mixed elasto-plastic contact lubrication and micro-lubrication, you must be closely related with the scratch tooth surface temperature analysis, first The contact temperature rise of gear tooth surface is analyzed, especially the high sliding start point and meshing end point. The tooth surface contact temperature rise is also the instantaneous moment of the Hertz macro area in gear contact
