が短時間で摩耗している。2. Description of the Related Art Oil free vane type fluid machines are manufactured by inserting vanes made of a self-lubricating material into a plurality of rotor grooves, and the centrifugal force generated by the rotation of the rotor causes the width of the vanes and the top to rotate to the inner wall of the casing. They were pressed against each other, keeping airtightness and compressing. Since this structure is oil-free, the vanes are made of a self-lubricating material such as carbon, and the vanes wear in a short time due to the high centrifugal force and high-speed sliding that press against the inner wall of the casing by the centrifugal force caused by the rotation. .

圧縮作用をする。The operation of the above means will be described. When the fluid machine is started, the vanes inserted in the rotor grooves rotate with the rotor as the rotor rotates. Due to this rotation, the vanes loaded in the rotor groove are swung outward by centrifugal force, and a strong contact pressure is generated in the cylinder inner wall direction. At the time of this rotation, a minute gap is maintained between the inner diameter of the casing and the vane top, or the gap is kept close to "zero", so that the casing does not come into contact with
Since the vane is inscribed in the casing ring or the bearing and rotates together with the bearing inner ring, the vane rotates integrally with the casing ring or the bearing inner ring without sliding on the casing ring, the bearing, or the casing inner wall. While doing a compression action.
