Abstract: front page image
(EN)A drive mechanism (10) is used, for example, in an orbiting radial motor (12) to rotate a sprocket (22) or in a multiple output speed increaser or reducer to control output. The drive mechanism (10) has a first member (16) positioned about and rotatable relative to a frame (14). A second member (18) is positioned generally between the frame (14) and first member (16) and engages and rotates the first member (16). The first member (16), for example, is connected to and rotates the sprocket (22) for driving a track of a work vehicle. The drive mechanism (10) has only a single element (34) for establishing the drive ratio of the first member (16) relative to the second member (18) and receiving and transmitting reaction torquing force on the second member (18) in response to the second member (18) engaging the first member (16). Thus, reaction loads on, for example, bearings (68, 70) supporting the second member (18) are substantially eliminated and the drive ratio can be widely varied.
(FR)Un mecanisme d"entrainement (10) est utilise par exemple dans un moteur radial orbital (12) pour faire tourner un pignon (22) ou dans un variateur ou reducteur de vitesse a sorties multiples pour commander la sortie. Le mecanisme d"entrainement (10) possede un premier organe (16) positionne autour d"une structure (14) et en rotation par rapport a celle-ci. Un second organe (18) est positionne d"une maniere generale entre la structure (14) et le premier organe (16), coopere avec le premier organe (16) et le fait tourner. Le premier organe (16) par exemple fait tourner le pignon (22) pour entrainer une piste d"un vehicule de travail. Le mecanisme d"entrainement (10) possede seulement un element (34) pour definir le rapport de transmission du premier organe (16) par rapport au second organe (18) et recevoir et transmettre la force de reaction du couple sur le second organe (18) en reponse a l"engagement du premier organe (16) par le second organe (18). Ainsi, des charges de reaction sur par exemple des paliers (68, 70) supportant le second organe (18) sont elimines et l"on peut faire varier le rapport de transmission dans de larges proportions.
