Abstract

PURPOSE: To improve the bearing rigidity by forming the bottom surface of a pocket into tapered form and generating a wedge-shaped oil film between a rotary shaft in the pocket part.
CONSTITUTION: The bottom surface 12 of a pocket 11 is formed into a tapered form which becomes gradually shallower along the direction of revolution of a rotary shaft 7. Pressurized oil is supplied into an oil feeding hole 16 from a high-pressure oil feeding line 6 having a throttle 5, and is pressurized oil flows into the pocket 11 through the oil feeding hole 16. Therefore, when the rotary shaft 7 is in highly eccentric state, pressurized oil forms a wedge-shaped oil film in the pocket 1, and the pressure in the pocket increases markedly by the dynamic pressure effect, and the bearing rigidity can be increased.
