Abstract
(EN)
This reduction gear 1 is provided with multiple rollers 4, an input member 10 (a first member) which has multiple first pockets 13 into which the multiple rollers 4 are inserted, a pair of fixed members 5 (a second member) which are provided on both sides of the input member 10 in the axial direction and which have a rolling element engagement groove 16 where both axial ends of the rollers 4 engage, and a pair of output members 31, 32 (a third member) which are provided between the input member 10 and the pair of fixed members 5 in the axial direction and which have multiple second pockets 17 into which the multiple rollers 4 are inserted. The multiple first pockets 13 are formed along a circle of which the center of curvature is eccentric from the rotation center X. The rolling element engagement groove 16 is formed along a wavy curve which alternately intersects with a pitch circle, the center of curvature of which is the rotation center X.

L'invention concerne un réducteur (1) qui est pourvu de multiples rouleaux (4), d'un élément d'entrée (10) (un premier élément) qui possède de multiples premières poches (13) dans lesquelles les multiples rouleaux (4) sont insérés, d'une paire d'éléments fixes (5) (un deuxième élément) qui sont disposés des deux côtés de l'élément d'entrée (10) dans la direction axiale et qui ont une rainure de mise en prise d'élément de roulement (16) où les deux extrémités axiales des rouleaux (4) viennent en prise, et d'une paire d'éléments de sortie (31, 32) (un troisième élément) qui sont disposés entre l'élément d'entrée (10) et la paire d'éléments fixes (5) dans la direction axiale et qui possèdent de multiples secondes poches (17) dans lesquelles les multiples rouleaux (4) sont insérés. Les multiples premières poches (13) sont formées le long d'un cercle dont le centre de courbure est excentré par rapport au centre de rotation X. La rainure de mise en prise d'élément de roulement (16) est formée le long d'une courbe ondulée qui croise alternativement un cercle primitif, dont le centre de courbure est le centre de rotation X.
