Dynamic bearing device having a thrust bearing portion |
摘要 |
The present invention has an object of improving wear resistance of a thrust bearing portion. A pressure is generated by a dynamic pressure effect of a lubricating oil in a thrust bearing gap between a thrust bearing surface including dynamic pressure generating grooves and a smooth thrust receiving surface so as to rotatably support a shaft member in an axial direction. The thrust receiving surface is formed as a flat surface, whereas an inclined plane is provided on the thrust bearing surface so as to provide a reduced portion having a decreasing axial width in a radially outward direction in the thrust bearing gap.
