Claims

[Scope of utility model registration request]

A compressor wheel is fixed to a common rotating shaft with a turbine wheel that is rotatably driven using exhaust gas, and the outer circumferential surface of the rotating shaft is radially supported by at least one radial bearing, and the side of the rotating shaft is In a supercharger bearing in which both end surfaces of a thrust collar fixed to a part are supported in the axial direction by two pairs of thrust bearings, the rotating shaft, the thrust collar, the radial bearing, and the thrust bearing are:
At least each sliding contact surface is made of a ceramic material, and the radial bearing is a cylindrical body with a groove for generating dynamic pressure on the bearing surface, and is fitted into the housing side or supported from the housing side via an elastic member. Alternatively, the thrust bearing is a gas bearing consisting of a plurality of tailing pad bodies each having a smooth bearing surface and pivotably supported from the housing side directly or through an elastic member, and the thrust bearing generates dynamic pressure on the bearing surface. It is a ring body with a groove for
- A bearing for a supercharger, characterized in that the bearing is configured as a gas bearing that fits into a housing side or is supported from a housing side via an elastic member.
