La présente invention concerne un mécanisme de transmission de rangée planétaire à vitesse linéaire variable, dans lequel une roue planétaire à vitesse linéaire variable (4) est pourvue d'une roue planétaire côté gauche (41) et d'une roue planétaire côté droit (42), la roue planétaire côté gauche (41) et la roue planétaire côté droit (42) étant raccordées par l'intermédiaire d'une pièce de raccordement de roues planétaires (43). Un premier orifice de planétaire (12), un premier orifice de porte-satellites (32) et un premier orifice de couronne interne (22) sont sur un même côté et agencés séquentiellement de l'intérieur vers l'extérieur, et un second orifice de planétaire (13), un second orifice de porte-satellites (33) et un second orifice de couronne interne (23) sont sur un même côté et agencés séquentiellement de l'intérieur vers l'extérieur. Un planétaire (1) s'engrène directement ou indirectement avec la roue planétaire côté gauche (41), une couronne interne (2) s'engrène directement ou indirectement avec la roue planétaire côté droit (42), et la pièce de raccordement de roues planétaires (43) est en raccordement emmanché avec une tige de raccordement de porte-satellites (31).
