Title (EN) SPEED REDUCER
(FR) RÉDUCTEUR DE VITESSE
(JA) 減速機
Abstract:
(EN) This speed reducer (1A) has a first speed reduction mechanism (20A) and a second speed reduction mechanism (30A). The first speed reduction mechanism (20A) has sun rollers (21A, 22A), a support part (62A), and planetary rolling bodies (23A). The second speed reduction mechanism (30A) has a fixed gear (32A) and a rotating gear (31A). The fixed gear (32A) and the rotating gear (31A) partially engage due to pressure received from the planetary rolling bodies (23A). Thus, the number of members in a power transmission unit between the first speed reduction mechanism (20A) and the second speed reduction mechanism (30A) can be reduced. Accordingly, a second stage of speed reduction occurs, and a compact speed reducer (1A) is achieved. Furthermore, the planetary rolling bodies (23A) make contact with the sun rollers (21A, 22A) and the support part (62A), thereby stabilizing the position of the planetary rolling bodies (23A). Accordingly, excessive contact between gear members does not easily occur.
(FR) La présente invention concerne un réducteur de vitesse (1A) présentant un premier mécanisme de réduction de vitesse (20A) et un second mécanisme de réduction de vitesse (30A). Le premier mécanisme de réduction de vitesse (20A) présente des rouleaux solaires (21A, 22A), une partie de support (62A) et des corps de roulement planétaires (23A). Le second mécanisme de réduction de vitesse (30A) présente un engrenage fixe (32A) et un engrenage rotatif (31A). L'engrenage fixe (32A) et l'engrenage rotatif (31A) viennent partiellement en prise en raison de la pression reçue à partir des corps de roulement planétaires (23A). Ainsi, le nombre d'éléments dans une unité de transmission de puissance entre le premier mécanisme de réduction de vitesse (20A) et le second mécanisme de réduction de vitesse (30A) peut être réduit. En conséquence, un second étage de réduction de vitesse se produit, et un réducteur de vitesse compact (1A) est obtenu. En outre, les corps de roulement planétaires (23A) entrent en contact avec les rouleaux solaires (21A, 22A) et la partie de support (62A), en stabilisant ainsi la position des corps de roulement planétaires (23A). Par conséquent, un contact excessif entre les éléments d'engrenage ne se produit pas facilement.
(JA) この減速機(1A)は、第1減速機構(20A)と第2減速機構(30A)とを有する。第1減速機構(20A)は、太陽ローラ(21A,22A)と支持部(62A)と遊星転動体(23A)とを有する。第2減速機構(30A)は、固定歯車(32A)と回転歯車(31A)とを有する。固定歯車(32A)と回転歯車(31A)とは、遊星転動体(23A)から受ける押圧によって、部分的に噛み合う。これにより、第1減速機構(20A)と第2減速機構(30A)との間の動力伝達部の部材数を低減できる。したがって、2段階の減速を行い、かつ小型の減速機(1A)を実現できる。また、太陽ローラ(21A,22A)と支持部(62A)とに遊星転動体(23A)が接触することで、遊星転動体(23A)の位置が安定する。したがって、歯車部材同士が強く当たり過ぎることが生じにくい。
