Abstract:
(EN) Provided is a deceleration device capable of supporting an undulating third crown gear in a highly rigid manner and further capable of improving efficiency. The deceleration device according to the present invention is provided with: a first crown gear 1; a second crown gear 2; a third crown gear 3 that has facing teeth 3a facing the first crown gear 1 and facing teeth 3b facing the second crown gear 2 and being arranged back to back to the facing teeth 3a; and cam parts 11, 12 that cause undulation of the third crown gear 3. The cam parts 11, 12 include a first cam 11 arranged closer to the first crown gear 1 than the third crown gear 3 and a second cam 12 arranged closer to the second crown gear 2 than the third crown gear 3. The third crown gear 3 is sandwiched between the first cam 11 and the second cam 12, first rolling bodies 15 are interposed between the first cam 11 and the third crown gear 3 in a rotatable manner, and second rolling bodies 17 are interposed between the second cam 12 and the third crown gear 13 in a rotatable manner.
(FR) L'invention concerne un dispositif de décélération, lequel dispositif est apte à soutenir un troisième couronne dentée plane ondulée d'une manière hautement rigide, et est de plus apte à améliorer l'efficacité. Le dispositif de décélération selon la présente invention comporte : une première couronne dentée (1) ; une deuxième couronne dentée (2) ; une troisième couronne dentée (3) qui a des dents de vis-à-vis (3a) faisant face à la première couronne dentée (1) et des dents de vis-à-vis (3b) faisant face à la deuxième couronne dentée (2), et qui sont disposées dos à dos vis-à-vis des dents de vis-à-vis (3a) ; et des parties de came (11, 12) qui provoquent une ondulation de la troisième couronne dentée (3). Les parties de came (11, 12) comprennent une première came (11) disposée plus près de la première couronne dentée (1) que de la troisième couronne dentée (3) et une seconde came (12) disposée plus près de la deuxième couronne dentée (2) que de la troisième couronne dentée (3). La troisième couronne dentée (3) est prise en sandwich entre la première came (11) et la seconde came (12), des premiers corps de roulement (15) sont interposés entre la première came (11) et la troisième couronne dentée (3) d'une manière rotative, et des seconds corps de roulement (17) sont interposés entre la seconde came (12) et la troisième couronne dentée (13) d'une manière rotative.
(JA) 波動運動する第三冠ギヤを高い剛性で支持することができ、効率も向上させることができる減速装置を提供する。 本発明の減速装置は、第一冠ギヤ1と、第二冠ギヤ2と、第一冠ギヤ1に対向する対向歯3aと第二冠ギヤ2に対向する対向歯3bとを背面合わせで持つ第三冠ギヤ3と、第三冠ギヤ3を波動運動させるカム部11,12と、を備える。カム部11,12は、第三冠ギヤ3よりも第一冠ギヤ1側に配置される第一カム11と、第三冠ギヤ3よりも第二冠ギヤ2側に配置される第二カム12と、を有する。第一カム11と第二カム12とで第三冠ギヤ3を挟み、第一カム11と第三冠ギヤ3との間に転がり運動可能に第一転動体15が介在し、第二カム12と第三冠ギヤ13との間に転がり運動可能に第二転動体17が介在する。
