<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a magnetic gear excellent in productivity, and to provide a magnetic gear. <P>SOLUTION: The magnetic gear includes a ring-like thin plate wherein feeble magnetic parts 10a and ferromagnetic parts 19b' are continued to each other in the circumferential direction. The ferromagnetic part 10b has a projection part 10b' projecting toward the only inner peripheral side, and the feeble magnetic part 10a is made of a metal structure mainly composed of austenite, which is non-melting and obtained by heating it for transformation, and both the ferromagnetic parts are arranged with a constant interval in the circumferential direction. The ferromagnetic part 10b is structured so that when one of an outer peripheral side end and an inner peripheral side end takes a part as an in-flow end of a magnetic flux, the other end takes a part as an outflow end for the magnetic flux. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
