Abstract

PURPOSE: To improve durability and the performance of seal, by eliminating the deterioration of the performance of seal by mounting a clearance between a cylindrical bush and a cylindrical bush holding portion material and by fitting the cylindrical bush to a shaft while shaping a small clearance between the cylindrical bush and the shaft.
CONSTITUTION: A cylindrical bush 17 is fitted to a shaft 1 so that a small clearance a be formed between the bush and the shaft 1, and a comparatively large diameter direction clearance and an axial direction clearance are mounted between a bearing car chamber 6, a cylindrical bush holding portion material, and a thermal shielding plate 18 in order that the bush can freely move in the diameter direction and the axial direction. The gas pressure receiving area of the bearing car chamber 6 side is made smaller than the gas pressure receiving area of the thermal shielding plate 18 side, and the cylindrical bush 17 is pushed to a flank of the bearing car chamber 6 by the differential pressure, thus preventing the leakage of gas. Even when vibration is formed in the shaft 1 being turned, the revolution of the shaft is not restiricted because there is the diameter direction clearance between the cylindrical bush 17 and the bearing car chamber 6 and motion in the diameter direction of the cylindrical bush is free.
