Abstract—

The spatial problem about the elastohydrodynamic lubricantion of a profiled roller accounting for the complicated geometry of the inlet boundary of the lubricant film is solved. This formulation simulates conditions of fully flooded or insufficient lubricantion, which may contain friction units such as gears and roller bearings. The set of integrodifferential equations with boundary conditions and inequalities describing elastohydrodynamic contact was solved by iterations based on the Newton method. The results demonstrate the significant influence of the geometry of the inlet boundary on the distributions of pressure and thickness of the lubricant film in the contact zone. It was shown that in the place where regions of the inlet boundary are slid into the contact zone, zones with lower values of pressure and thickness of the lubricant film as compared with the case of fully flooded lubrication appear towards the flux of the lubricant.

考虑润滑膜入口边界几何形状的异型滚子弹性流体动力接触数值模拟

摘要-

解决了由于润滑膜入口边界的复杂几何形状而导致的异型滚子弹性流体动力润滑的空间问题。该配方模拟完全浸没或润滑不足的条件，其中可能包含摩擦单元，如齿轮和滚子轴承。通过基于牛顿法的迭代求解具有边界条件和描述弹性流体动力接触的不等式的积分微分方程组。结果表明，入口边界的几何形状对接触区的压力分布和润滑膜厚度有显着影响。结果表明，在入口边界区域滑入接触区的地方，
