Abstract:
(EN) This wave gear speed reducer comprises: a rigid internal gear (27); a flexible external gear (36) arranged in the interior of the rigid internal gear (27); a wave generator (37) arranged in the interior of the flexible external gear (36); an input shaft (48) connected to a center portion of the wave generator (37); a plurality of elastic members (60a); and a plurality of spherical members (60b) each secured to one end of an elastic member (60a). The wave generator (37) and the input shaft (48) are provided with, along the circumferential direction, a plurality of recesses (48a, 371a) opening at the connection surface of the wave generator (37) and the input shaft (48). Each elastic member (60a) is arranged in a recess (48a) of the input shaft (48), and a spherical member (60b) is secured to the one end of the elastic member that is on the open side of the recess (48a). Each spherical member (60b) has a portion that protrudes into a recess (371a) of the wave generator (37).
(FR) L'invention porte sur un réducteur de vitesse d'engrenage à ondes comprenant: un engrenage interne rigide (27); un engrenage externe flexible (36) disposé à l'intérieur de l'engrenage interne rigide (27); un générateur d'ondes (37) disposé à l'intérieur de l'engrenage externe flexible (36); un arbre d'entrée (48) relié à une partie centrale du générateur d'ondes (37); une pluralité d'éléments élastiques (60a); et une pluralité d'éléments sphériques (60b) fixés chacun à une extrémité d'un élément élastique (60a). Le générateur d'ondes (37) et l'arbre d'entrée (48) sont pourvus, le long de la direction circonférentielle, d'une pluralité d'évidements (48a, 371a) s'ouvrant au niveau de la surface de connexion du générateur d'ondes (37) et de l'arbre d'entrée (48). Chaque élément élastique (60a) est disposé dans un évidement (48a) de l'arbre d'entrée (48), et un élément sphérique (60b) est fixé à l'extrémité de l'élément élastique qui est sur le côté ouvert de l'évidement (48a). Chaque élément sphérique (60b) présente une partie qui fait saillie dans un évidement (371a) du générateur d'ondes (37).
(JA) 本発明による波動歯車減速機は、剛性内歯車(27)と、剛性内歯車(27)の内部に配置された可撓性外歯車(36)と、可撓性外歯車(36)の内部に配置された波動発生器(37)と、波動発生器(37)の中央部に接続された入力軸(48)と、複数の弾性部材(60a)と、弾性部材(60a)の一端にそれぞれが固定された複数の球状部材(60b)とを備える。波動発生器(37)と入力軸(48)は、波動発生器(37)と入力軸(48)との接続面で開口する凹部(48a、371a)を周方向に複数備える。弾性部材(60a)のそれぞれは、入力軸(48)の凹部(48a)の中に設置され、凹部(48a)の開口側の一端に球状部材(60b)が固定されている。球状部材(60b)のそれぞれは、一部が波動発生器(37)の凹部(371)aの中に入り込んでいる。
