Abstract
A thrust roller bearing apparatus is such as to be installed in a hydraulic mechanism to adjust a gap produced between components when they are assembled in the hydraulic mechanism and is configured such that a back side of a race forms an oil pressure chamber in a space produced between the back side of the race and a mating member which the race oppositely faces, so that the race bears a pressure from the oil pressure chamber so as to be displaced axially to thereby carry out the adjustment of the gap.
Claims3
A thrust roller bearing apparatus installed in a gap occurs between first and second members which constitute a hydraulic mechanism, the thrust roller bearing apparatus comprising:
- a race axially movably disposed inside the gap;
- and
- a plurality of rollers disposed between the race and the first member,
- wherein an oil pressure chamber is defined between the race and the second member opposed to the race in an axial direction, and
- wherein the oil pressure chamber presses and displaces the race in the axial direction to increase a capacity of the oil pressure chamber as internal pressure of the oil pressure chamber increases, thereby adjusting the gap.
