An outer diameter side magnet field pole piece assembly for a magnetic gear which is disposed on an outer circumferential side of a plurality of magnetic pole pieces disposed on an outer circumferential side of the outer diameter side magnet field pole piece assembly along a circumferential direction, includes: a plurality of magnetic pole pairs disposed on the outer circumferential side of the plurality of magnetic pole pieces along the circumferential direction; and a support member for supporting the plurality of magnetic pole pairs from the outer circumferential side. A space along an axial direction is formed in at least a part between an outer circumferential surface of each of the plurality of magnetic pole pairs and an opposite surface of an inner circumferential surface of the support member opposite to the outer circumferential surface of each of the plurality of magnetic pole pairs.

Outer diameter side magnet field and magnetic gear

A centrifugal compressor includes: a drive shaft; a wheel gear; a driven shaft; a pinion gear disposed to be rotatable together with the driven shaft, and meshing with the wheel gear; an impeller rotating together with the driven shaft; a thrust collar restricting a displacement of the driven shaft in an axial direction by colliding with the wheel gear in the axial direction; and a plurality of bolts disposed at intervals in a circumferential direction and each extending in the axial direction to fix the thrust collar and the pinion gear. Each of the plurality of bolts fix the thrust collar and the pinion gear in a state where each of the plurality of bolts are inserted from a position opposite to the wheel gear with reference to the thrust collar in the axial direction.

Centrifugal compressor

A power transmission device includes a first power transmission path for transmitting a driving force of a motor to one driven shaft, and a second power transmission path for transmitting the driving force of the motor to another driven shaft. At least one of the first power transmission path or the second power transmission path includes a first intermediate rotor fixed to an output shaft of the motor, a second intermediate rotor rotated by the first intermediate rotor and moving arcuately along an outer circumference of the first intermediate rotor, a driving shaft rotated by the second intermediate rotor and transmitting the driving force to the one driven shaft or the another driven shaft. The driving shaft is configured to move in a direction perpendicular to an axial center direction of the driving shaft in accordance with movement of the second intermediate rotor around the first intermediate rotor.

Power transmission device and rolling mill

A rotary electric machine includes an armature unit including an annular rotor configured to be rotatable around an axis and a stator disposed on a radially outer side of the annular rotor; an input or output shaft coupled at a first end thereof to an external device and extending along an axial direction of the annular rotor in a central space defined in a central portion of the annular rotor; and a coupling device disposed closer to a second end of the input or output shaft than an end of the annular rotor adjacent to the external device in the axial direction of the annular rotor and connecting the input or output shaft and the annular rotor so as to be able to transmit a torque.
