Abstract

Dans cet écrou cylindrique de vis à billes 2 destiné à être vissé sur une tige formant vis à billes 1, par l'intermédiaire d'un certain nombre de billes 3, les surfaces périphériques extérieures des deux épaulements d'extrémité du corps 30 de l'écrou sont munies de gorges 32 de circulation des billes, dans lesquelles les billes de roulements 45 à contact angulaire peuvent rouler le long des surfaces périphériques extérieures, tandis qu'une première extrémité dudit corps 30 de l'écrou comporte un prolongement cylindrique 35 qui possède un diamètre extérieur inférieur au moins à celui desdites gorges 32 de circulation des billes et un diamètre intérieur supérieur au diamètre extérieur dudit arbre formant vis à billes 1, et auquel est raccordé un organe d'entraînement en rotation M2 servant à entraîner en rotation le corps 30 de l'écrou. Application notamment aux transmissions du type à écrou et vis à circulation de billes. (CF DESSIN DANS BOPI)In this cylindrical ball screw nut 2 intended to be screwed onto a ball screw rod 1, by means of a number of balls 3, the outer peripheral surfaces of the two end shoulders of the body 30 of the The nut are provided with grooves 32 for the circulation of the balls, in which the angular contact bearing balls 45 can roll along the outer peripheral surfaces, while a first end of said body 30 of the nut has a cylindrical extension 35 which has an outside diameter at least less than that of said grooves 32 for the circulation of the balls and an inside diameter greater than the outside diameter of said ball screw shaft 1, and to which is connected a rotational drive member M2 serving to drive in rotation the body 30 of the nut. Application in particular to transmissions of the nut and screw type with recirculating ball. (CF DRAWING IN BOPI)
