一、绪言机械工程中运动副间的线接触问题,例如直齿轮的啮合、滚子轴承的接触、滚子从动件盘状凸轮传动等等,都可以用两个相互滚滑的滚子来模拟。从润滑的角度来看,还可进一步简化为一个滚子和一个平面之间的滚滑。Martin 首先研究了刚性滚子间稳态润滑油膜的性态,求出了最小油膜厚度的表达式。Gatcombe 研究了粘度随压力变化的润滑油所润滑的刚性滚子间润滑油膜的性态。Dowson 等研究过准稳态常粘度润滑油所润滑的刚性滚子间润滑油膜的性态。佐佐木外喜雄等研究过载荷突变时 I. INTRODUCTION The line contact problems between mechanical pairs of mechanical engineering, such as spur gear meshing, roller bearing contact, roller follower disc cam transmission, etc., can be achieved with two reciprocating rollers simulation. From a lubrication point of view, this can be further simplified into a roll between a roller and a plane. Martin first studied the behavior of the steady lubricant film between rigid rollers and obtained the expression of the minimum oil film thickness. Gatcombe studied the behavior of rigid roller lubricant films lubricated with a lubricant of varying viscosity. Dowson et al. Studied the behavior of the lubricant film between rigid rollers lubricated by quasi-steady state and constant viscosity lubricants. Sasaki Wai Hsiung and other research overload mutation
