the input high speed shaft of the Wuma variable gear motor

Wuma variable gear motor, The rim of the fixed gear is press fitted onto an outer ring made of permeable steel, and the rim of the orbiting gear is press fitted onto a central permeable steel disk. In cycloidal speed reducers, the orbiting gear is driven by a crank of the input high speed shaft. Because the power gearbox of the prototype magnetic unit built is rather large, 26:1, which would require a small crank radius.
