Title (EN) DEVICE FOR DRIVING A TOOTHED WHEEL BY A STEP-BY-STEP BIPOLAR MOTOR
(FR) DISPOSITIF D"ENTRAINEMENT D"UNE ROUE DENTEE PAR UN MOTEUR PAS A PAS BIPOLAIRE
Abstract: front page image
(EN)Between two plates (1, 2) forming the support of a step-by-step motor driving a toothed wheel (5) are arranged a dissymmetrical stator (3) and a bipolar magnet rotor (4) mounted on a rotating shaft (41), with some axial play between two bearings (42, 43). These armatures (30, 31) making up the stator (3) are onset with respect to the transverse symmetrical plane of the rotor (4) so as to create a force F driving the rotor towards the plate (1). A driving crank of the wheel (5) by the step-by-step motor is composed of two plates (44, 45), concentric and perpendicular to the shaft (41), carrying between them two pins (46, 47) diametrically opposite and perpendicular to said plates. The base (460, 470) of the pins (46, 47) is cone-shaped.
(FR)Entre deux platines (1, 2) constituant le support d"un moteur pas a pas entrainant une roue dentee (5) sont disposes un stator (3) dissymetrique et un rotor (4) a aimant bipolaire monte sur un arbre (41) tournant, avec un certain jeu axial, entre deux paliers (42, 43). Ces armatures (30, 31) constituant le stator (3) sont decalees par rapport au plan de symetrie transversal du rotor (4) de facon a creer une force F entrainant le rotor vers la platine (1). Une manivelle d"entrainement de la roue (5) parle moteur pas a pas est constituee par deux plateaux (44, 45), concentriques et perpendiculaires a l"arbre (41), porteurs entre eux de deux goupilles (46, 47) diametralement opposees et perpendiculaires auxdits plateaux. L"embase (460, 470) des goupilles (46, 47) est conique.
