Title: Magnetic gear device
Inventor: NAKAMURA KENJI
IPC: F16H49/00
Filed: 2021-05-11
Abstract: To provide a magnetic gear device which has less torque ripples while maintaining large transmission torque in a non-contact manner.SOLUTION: A magnetic gear device 100 has two rotators (rotors) each having a plurality of permanent magnets, and a magnetic piece body having a plurality of magnetic pieces formed of soft magnetic materials between the two rotators, such that the magnetic gear device transmits rotation by modulating magnetic fluxes of magnet pole number ratios via the magnetic pieces. For securing a change gear ratio with less torque ripple of transmission torque, torque ripples become large at a change gear ratio of an integer multiple, which results in the magnetic gear device being subject to restrictions such as being extremely disadvantageous as a product. In the present invention, by combining irregularly-shaped magnetic body pieces which are individually set in the shapes of the magnetic pieces of the magnetic piece body arranged between the rotators, the torque ripples of the magnetic gear device can be reduced. It is therefore possible to provide a magnetic gear device that is not restricted by the change gear ratio.SELECTED DRAWING: Figure 1
