这是有用的和有趣的，以澄清润滑脂润滑的行为，这是可用于滚动轴承。本文导出了一个耦合宾汉体流体动力学方程和齿轮材料弹性力学方程的非线性积分方程。通过数值求解该方程，可以清楚地看到宾厄姆流中核心的形成对两圆柱间弹流润滑的影响，核心的形成过程是弹流问题的重要组成部分。并对薄膜轮廓进行了测量，与分析结果进行了比较.
It is useful and interesting to clarify the behavior of grease lubrication which is available on rolling bearings. To discuss such a problem, a nonlinear integral equation coupling the hydrodynamic equation of a Bingham solid and the elasticity equation of gearing materials is derived in this paper. Solving the equation numerically, the effect of core formation in a Bingham flow on the elastohydrodynamic lubrication between two cylinders becomes clear, and the process of core formation constitute an important part of the elastohydrodynamic problem. The measurements of film profiles also are carried out to compare with the analytical results.
