Abstract
Magnetic gears used in a trial have superior performance characteristics. A magnetic spur gear meshes both internal and external gearing by exchanging the center distance. A magnetic bevel gear operates in the same way as a spur gear by exchanging the intersecting axle. A magnetic worm gear is constructed compactly in such a way that the worm is involved inside the space (torus) of a worm wheel. A magnetic skew gear is positioned at any center distance between the pinion and gear. Recently trial use has been made of magnetic planetary and diffential gears as accelerators for wind power generators. This paper describes the effect of the performance characteristics of correcting the whole depth which is composed of a permanent magnet. As a result, it is shown that the ordinary performance characteristics are maintained when the whole depth is reduced by one half.
