Abstract
PURPOSE: To prevent occurrence of the thermal displacement in an axial direction, by separately providing thrust bearing pockets and cylinder mechanisms and allowing one of the both inner end side parts of bearing members to function as a static pressure thrust bearing part and the other as a cylinder with selecting feed of pressure fluid.
CONSTITUTION: In both end sides of a large contour part 14 of a shaft member 13 and inner end side portions of bearing members 11, 12 located at a face-to-face position to said both end sides, thrust bearing pockets 26, 27 and cylinder chambers 24, 25 are separately provided. Then supply of pressure oil to the pockets 26, 27 and the cylinder chambers 24, 25 is performed by selecting oil line selecting members 30, 33 in such a manner as to the cylinder chamber 25 when supplied to the pocket 26 while to the cylinder chamber 24 when supplied to the pocket 27, thus one of the inner end side parts of the bearing members 11, 12 is allowed to function as a static pressure thrust bearing part while the other as a cylinder. In this way, occurrence of the axial thermal displacement can be prevented even for a grindstone 15 mounted to either side of the shaft member 13.
