Hydrodynamic bearing, has shaft around which lubricant passage paths extend between shafts external surface and bearing bushs internal surface, and having ridges defining average curves which extend on ridged surface in sinusoidal manner

摘要

The bearing has a shaft (10) rotatably mounted in a bearing bush (14). An external surface (12) of the shaft extends opposite to an internal surface (16) of the bush. Lubricant passage paths extend around the shaft between the surfaces (12, 16). The paths have ridges arranged in the surfaces which form a ridged surface. The ridges define average curves which extend on the ridged surface in a sinusoidal manner.
