Title (EN) CANTILEVERED SCREW ASSEMBLY WITH SPEED REDUCER AND PIVOTING TORQUE ARM
(FR) ENSEMBLE VIS EN PORTE-À-FAUX AVEC RÉDUCTEUR DE VITESSE ET BRAS DE COUPLE PIVOTANT
Abstract:
(EN) A cantilevered screw assembly comprising a speed reducer to facilitate rotation of a screw. The speed reducer may be connected to a torque arm that is adapted to control or limit undesired movement (e.g., wobbling, orbital movement, etc.) of the screw during operation. In effect, one exemplary embodiment of a speed reducer may essentially float on a pivoting torque arm (and the shaft of the screw) such that the torque arm is adapted to limit undesired movement of the speed reducer and screw. As a result, an exemplary embodiment may eliminate the need for alternative drive systems or other means to control undesired movement of the screw. An exemplary embodiment may be particularly useful for light or infrequent duty or other small-scale applications to reduce the likelihood of a breakage of a screw or another portion of a cantilevered screw assembly (e.g., the bearing(s) or bearing assembly, the gears, etc.).
(FR) L'invention concerne un ensemble vis en porte-à-faux comprenant un réducteur de vitesse pour faciliter la rotation d'une vis. Le réducteur de vitesse peut être relié à un bras de couple qui est conçu pour commander ou limiter un mouvement indésirable (par exemple, un mouvement oscillant, un mouvement orbital, etc.) de la vis pendant le fonctionnement. En effet, un exemple de mode de réalisation d'un réducteur de vitesse peut essentiellement flotter sur un bras de couple pivotant (et l'arbre de la vis) de telle sorte que le bras de couple est conçu pour limiter le mouvement indésirable du réducteur de vitesse et de la vis. Par conséquent, un mode de réalisation donné à titre d'exemple peut éliminer le besoin de systèmes d'entraînement alternatifs ou d'autres moyens pour commander un mouvement non souhaité de la vis. Un mode de réalisation donné à titre d'exemple peut être particulièrement utile pour des applications légères ou peu fréquentes ou d'autres applications à petite échelle afin réduire le risque de rupture d'une vis ou d'une autre partie d'un ensemble vis en porte-à-faux (par exemple, le ou les paliers, les engrenages, etc.).
