一、前言目前,油膜轴承的设计计算都假设轴承是刚性的。基于这个假设设计的油膜轴承,在一般条件下是与实际情况相当一致的;但当油膜压力高到一定程度后(比如说140kgf/cm~2即2000磅力/时~2),两者就有明显的差别了,轴承的弹性变形就不能忽略不计了。关于油膜轴承的弹流计算,已做了许多工作。H.R.Higginson研究了无限长轴承衬套的弹性变形的影响,O’Donoghue,D.K.Brighton,C.J.R.Hooke研究了无限长轴承轴颈和衬套变形的影响。计算中,他们提出用h=h_0+ecosφ+δ来描述考虑弹性变形后轴
First, the preface At present, the oil film bearing design calculations assume that the bearing is rigid. Oil film bearings based on this assumption are quite consistent with the actual conditions under normal conditions; however, when the oil film pressure reaches a certain level (for example, 140 kgf / cm ~ 2 or 2000 lbf / h ~ 2) There are obvious differences, the elastic deformation of the bearings can not be ignored. A lot of work has been done on the calculation of the spring flow of oil film bearings. H.R. Higginson studied the effect of elastic deformation of an infinitely long bearing bushing, O’Donoghue, D.K.Brighton, C.J.H.Hooke, studied the effects of infinite bearing journal and bushing deformation. In the calculation, they proposed to use h = h_0 + ecosφ + δ to describe the elastic deformation axis
