PURPOSE:To make a shock smaller at the time of selection from c.w. to c.c.w. rotation and vice versa, by forming both internal and external gears into involute toothing, while setting a difference in the number of teeth down to one, and supporting a carrier pin with a body via a support block. CONSTITUTION:An eccentric part 24 is installed in an input shaft 23, and external gears 30 and 31 are rotatably fitted in this eccentric part 24. In addition, this eccentric part 24 is supported by a body 1 and a support block 33 via bearings 40 and 41. Each carrier pin 25 pierces through these external gears 30 and 31 and is supported by the support block 33 and the body 1. And, a difference in the number of teeth between an internal gear 28 and these external gears 30 and 31 is one, while a tooth form is of involute toothing and that it is formed into a low tooth, insomuch that trochoidal interference may not happen at the time of intermeshing rotation. |
