Abstract
PURPOSE:To prevent vibration by providing a elastic body pivotally mounting a fixed side thrust pad on back face to the axial direction for giving pre-load to a dynamic pressure thrust bearing in spiral channel. CONSTITUTION:A fixed side thrust pad body 10 is equipped with pivotally mounted by a spring 9 on a position, which opposes to a rotation side thrust pad face 6 formed on front face of a impeller 4, on inner wall of a front casing 7. A dynamic pressure thrust bearing in spiral channel, existing between the rotation side thrust pad face 6 and the fixed side thrust pad face 10, is pre- loaded by the spring 9. Therefore,the same doesn't cause unstable vibrational state like chattering and the like even if in a case of sudden changing of thrust force in magnitude or in direction.
