PURPOSE:To simplify the structure and to improve the durability, in a differential reduction gear utilizing eccentric motion, by taking out the rotation of output shaft as the rotation of internal gear thereby eliminating conventional Ohdham coupling. CONSTITUTION:An eccentric disc section 2 is formed at the end of input shaft 1 for supporting the frame 3 rotatably through a bearing 4 to gear a spar gear 6 fixed to the outercircumferential section of said eccentric section 2 through a bearing 5 with an internal gear 7 integral with the output shaft 8 located on same axis with that of input shaft 1. The output shaft 8 is supported rotatably on the frame 3A through a bearing 9 to support the end section 1b projecting from the eccentric section 2 onto the center line C1 of input shaft 1 by means of the internal gear 7 rotatably through a bearing 10. Frame fixing pin 12 is projected from the spar gear 6 and coupled through a fixed pin 11 projecting from the frame 3 and a link 13 while separating by distance (e) from the eccentric section 2. |
