There is. This gearless reducer has an eccentric round groove and a sinusoidal groove consisting of a certain integer n waves formed on the opposing surfaces of the driving and driven rotary plates, and both rotations occur at the intersection of both grooves. A ball inserted into a radial window provided in a fixed plate placed between the plates is engaged with both cam grooves to transmit power. The reduction ratio is always determined to be 1/n by the wave number n of the sine wave, since the driven rotary plate rotates by one period of the sine wave for one rotation of the drive rotary plate. For this reason, in the prior art, the setting of the gear ratio is restricted, and it is not possible to freely set the gear ratio to a value having a fraction below the decimal point.
