通过等温富油工况下滚子摩擦副弹流数值解研究表明,工程对数滚子具有良好的润滑特性,轻载时呈现大椭圆比点接触的特征,最小油膜厚度出现在中部,轴向油膜形状和压力分布比较均匀.载荷增大端部出现闭合效应,油膜压力局部升高,形成的封油作用使中部油膜略微增厚,最小油膜厚度转移至端部,厚度减小;速度增加使闭合效应加剧 The numerical solution of the roller frictional sub-Elasto flow under the condition of isothermal and rich oil shows that the logarithmic roller has good lubrication characteristics and has the characteristics of large oval point contact at light load. The minimum oil film thickness appears in the middle and the axial The shape and pressure distribution of the oil film are relatively uniform. Closure effect occurs at the end of the increased load, and the pressure of the oil film locally increases. The oil seal effect formed is slightly thickening of the middle oil film and the minimum thickness of the oil film is transferred to the end, Closure effect intensified
