Abstract
Oil film seals of large diameter sometimes show long-period cyclic def ormation of the floating seal ring whose rotation is constrained,by a stopper pin. Cyclic change of deformation and oil film temperature may cause fatigue damage of the seal ring after long-term operation. We p resent a theory for the mechanisms of thermal deformation and its peri odic transformation, the results of which agree well with those of mea surements, and which provides a practical design criterion to prevent this phenomenon.
