Abstract

PURPOSE: To improve the rigidity of the bearing in combination of a narrower pocket close to the grind stone and a broader pocket on the pulley side each formed on the bearing surface.
CONSTITUTION: A narrower pocket 17 is fofmed close to the grind stone and a broader pocket 18 close to the pulley as pair on the bearing surface of the bearing member 11. This one pair of the pockets are communicated to a hole 18 drilled in the bearing member 11 to make one pocket. A pressure fluid is fed to the pocket 18 through a nozle 22a while to the pocket 17 through a communicating hole 19. Thus, a fluid film is formed between the shaft member 13 and the bearing surfaces 11a and 12a. Then, from the pockets 17 and 18, the pressure fluid properly flows to a drain hole 26 through a fine clearance formed between the circumference of the shaft member 13, and sections 17a and 18a, and small land sections 17b and 18b. In this manner, a static pressure develops in the pockets 17 and 18 according to the bearing clearance.
