Claims

[Scope of utility model registration request]

A rotating shaft provided with a thrust collar is rotatably supported in a casing containing lubricating oil, and an oil ring collar having a groove on the inner periphery on the outer periphery of the thrust collar is relatively rotatable and fixed to the casing side. In the lubricating oil circulation device, which forms a circulating flow of lubricating oil between the outer circumference of the thrust collar and the groove on the inner circumference of the oil ring collar by rotating the rotating shaft, the groove width is gradually changed and the groove depth is gradually changed. A lubricating oil circulation device characterized in that an oil ring collar having a changed oil ring collar or an oil ring collar having a groove width gradually changed or a groove depth gradually changed is arranged around the outer periphery of the thrust collar.
