Abstract: In a rotating body and a rotating electric machine, a rotary shaft made of a magnetic body, a rotor fixed to the rotary shaft, and a pair of bearing sleeves for an air bearing that have a cylindrical shape, are mounted on one end portion and the other end portion of the rotor in an axial direction, and have wear-resistant coating layers on outer peripheral surfaces are provided, and the pair of bearing sleeves for an air bearing are provided with the wear-resistant coating layers before assembly to the rotary shaft.

Abstract: In a rotating body, a rotating electric machine, an electric compressor, and a method of manufacturing a rotating body, a rotary shaft having a pair of flange portions provided at an interval in an axial direction, an iron core made of a magnet that has a cylindrical shape, is divided into a plurality of pieces in a circumferential direction, and is disposed between the pair of flange portions on an outer side of the rotary shaft in a radial direction, and a holding sleeve that has a cylindrical shape, is disposed on an outer side of the iron core, and has one end portion and the other end portion in the axial direction fixed to outer peripheral portions of the pair of flange portions are provided.

Abstract: The back surface of a hub of a compressor wheel mounting structure according to the present invention comprises a recessed surface which is formed from the outer peripheral end of a flat surface to the outer peripheral edge of the back surface.

Abstract: In a silencer, holes are disposed in one row with intervals to each other along one direction, holes forming the one row are disposed in a plurality of rows in a direction perpendicular to the one direction, and positions of the holes in adjacent rows are shifted in the one direction and disposed in a zigzag pattern. A disposition interval of the holes of an outer edge hole row forming one row in at least two sides opposite to each other in the silencing porous plate is set to be larger than a disposition interval of the holes of a row inside the outer edge hole row.

Abstract: An object of the present invention is to provide a gas turbine combustor with improved fatigue resistance of a combustor. It is possible to intentionally reduce a stiffness of each of flanges of upper and lower walls of an end portion (outlet) of the tail pipe of the gas turbine combustor. It is possible to reduce a stiff difference between the upper and lower walls of the end portion (outlet) of the tail pipe section and side walls. Thus, it is possible to reduce compulsion deformation caused due to thermal stress generated in the end portion (outlet) of the tail pipe section on the operation of the conventional gas turbine combustor, and to reduce high stress easy to generate in the side plate. As a result, the gas turbine combustor with high fatigue resistance can be realized.
