Abstract

PURPOSE: To provide a bearing apparatus, wherein parts of rotary shaft are beveled to arrange sealed wedge-like spaces between the rotary shaft and a bearing, so that the favorable lubrication can be effected by pumping action due to the wedge effect.
CONSTITUTION: Bevels 2 are arranged on a rotary shaft 1, which will be born by a sintered bearing 3 that is pressed in a frame 4, to form sealed spaces S between the bevels 2 and the bearing 3. The spaces S includes wedge-like spaces a and b, and when the bearing apparatus is rotated, the lubricating oil introduced into the space a of the bearing 3 will be forced into the space b to feed the lubricating oil effectively onto the sliding surface of the rotary shaft 1.
