Inventor: OKUMA ISAMU
IPC: F16H1/32
Filed: 2012-08-09
Abstract: PROBLEM TO BE SOLVED: To increase torsional rigidity.SOLUTION: In a wave gear speed reducer 190, a rotation of an input shaft causes two planetary rollers 3 to rotate inside a ring external gear 6a engaging with an internal gear 7a while revolving to elastically deform the external gear 6a in an ellipse, and changing two engagement positions of the internal gear and the external gear causes the rotation of the input shaft 11 to be transmitted to an output shaft 13 connected to the external gear while a speed of the rotation is reduced. The wave gear speed reducer includes an elastically-deformable flex ring 5 between the external gear and the planetary roller. The flex ring can inhibit the external gear in the vicinity in a circumferential direction of the planetary roller from bending toward the inside of the ellipse. Accordingly, the number of engagement gears between the external gear and the internal gear is increased and the torsional rigidity in a structure on an output shaft side can be improved.
