Title
(EN) FORCE SENSING SLEW DRIVE
(FR) ÉLÉMENT D'ENTRAÎNEMENT ROTATIF À DÉTECTION DE FORCE
Abstract
(EN)
A sensor is used in measuring the torque applied to a slew drive. The slew drive includes a worm gear and a worm wheel and the sensor is coupled with a securing device that is used to secure the worm gear to the slew drive housing. The sensor generates a signal which is indicative of the torque on the worm wheel. The worm gear is secured to the slew drive housing by a first bearing and a second bearing. Two end plates and eight bolts are also used to further secure the worm gear and the bearings to the slew drive housing. By tightening the bolts, a compressive force is applied on the worm gear through the bearings. The applied torque on the worm wheel causes an axial force on the worm gear. The axial force is transmitted through the worm gear, the bearings, the end plates, and the bolts. One or more sensors can be embedded in one or more of the end plates or the bolts to measure the strain, in the end plates or the bolts, due to the axial force. A control device receives the signal from the sensor and stores, analyses, and/or communicates the signal.

Un capteur est utilisé pour mesurer le couple appliqué à un élément d'entraînement rotatif. L'élément d'entraînement rotatif comprend une vis sans fin et une roue à vis sans fin et le capteur est couplé à un dispositif de fixation qui est utilisé pour fixer la vis sans fin au boîtier d'élément d'entraînement rotatif. Le capteur génère un signal qui indique le couple sur la roue à vis sans fin. La vis sans fin est fixée au boîtier d'élément d'entraînement rotatif par un premier palier et un second palier. Deux plaques d'extrémité et huit boulons sont également utilisés pour fixer davantage la vis sans fin et les paliers au boîtier d'élément d'entraînement rotatif. En serrant les boulons, une force de compression est appliquée sur la vis sans fin par l'intermédiaire des paliers. Le couple appliqué sur la roue à vis sans fin provoque une force axiale sur la vis sans fin. La force axiale est transmise à travers la vis sans fin, les paliers, les plaques d'extrémité et les boulons. Un ou plusieurs capteurs peuvent être incorporés dans une ou plusieurs des plaques d'extrémité ou des boulons pour mesurer la déformation, dans les plaques d'extrémité ou les boulons, due à la force axiale. Un dispositif de de contrôle reçoit le signal du capteur et stocke, analyse et/ou communique le signal.
