ハイブリッド式磁気歯車のかみ合い性能に関する一考察 : かみ合い領域における荷重分担のメカニズム  [in Japanese] Meshing performance Characteristics of Hybrid-Type Magnetic Gears : Mechanism of Load-Sharing in the Contact Zone  [in Japanese]

As a result of developments in science technology, non-contact gears are needed for vibrationless, noiseless, and oilless operation. We have proposed non-contact hybrid-type magnetic gears, which consist of electromagnetic gear (on the driving side) and permanent magnetic gear (on the driven side). This paper describes the meshing performance characteristics and mechanism of load-sharing in the contact zone. As a result, it was found that the following considerations must be taken account of in magnetic gear design. (1) The meshing zone of magnetic gear consists of intersecting and main contact zones. (2) The ratio of load-sharing between the intersecting and main contact zones is 3:7. (3) The intersecting contact zone is effective for decreasing the thrust load, and the main contact zone is useful for increasing the load-carrying capacity.
