PURPOSE:To remove backlash of the whole mechanism by disposing two-split pinions or transmission gears in such a manner that the phase of one part is shifted from that of the other by angle backlash. CONSTITUTION:Angle backlash between an engaging portion of at least one set of external gears with an internal gear 10 and an eccentric body bearing 9 is 0 in the normal or reverse direction. A pinion 2 or transmission gears 31, 32 are axially divided into two parts, and the phase of one of the two-split pinion 2 or transmission gears 31, 32 is shifted from the other thereof for angle backlash. In this arrangement, backlash of the whole mechanism can be removed. |
