针对螺旋锥齿轮乏油弹流润滑(SEHL),基于微分几何和空间曲面啮合原理,进行了螺旋锥齿轮轮齿加载接触迹、接触点主曲率及轮齿间载荷分配的分析.通过椭圆乏油弹流润滑理论,建立了螺旋锥齿轮乏油弹流润滑分析的数学模型和寿命预测模型.以某直升机传动系统螺旋锥齿轮为例,分析验证了所建立的螺旋锥齿轮乏油弹流润滑寿命预测模型的有效性,为螺旋锥齿轮乏油弹流润滑寿命预测提供了一种有效的方法.

Taking aim at starved elaslohydrodynamic lubrication (SEHL) of spiral bevel gears, the analyses of loaded tooth contact track, main curvature of contact point, and load distribution between teeth were performed by differential geometry and space surface mesh theory. By the theory of SEHL at elliptical contact system, the mathematic model and life predication model of SEHL for spiral bevel gears were established. By the analysis on the aviation spiral bevel gears concerning a certain helicopter transmission system, it was proved that the life predication model on SEHL of spiral bevel gears is valid, to provide an effective method for the life prediction.
