Abstract
(EN)
Rolling screw (1) comprising a first threaded male member (6), a second threaded member (3), means (5) that permit said second threaded member (3) to rotate freely in relation to the housing (2), as well as means (7) that permit to maintain fixed and constant the position of the axis of said first threaded member (6) in relation to the housing (2). Means of synchronisation are also foreseen for the relative rotation between said first member (6) and said second member (3). Said screw is characterised in that at least one of the two threaded members presents a threading conformation such to permit the transmission of the rotation motion to another element without relative tangential sliding action.
(FR)
L'invention concerne une vis à billes (1) comprenant un premier élément mâle fileté (6), un deuxième élément fileté (3), des moyens (5) qui permettent audit deuxième élément fileté (3) de tourner librement par rapport au logement (2), ainsi que des moyens (7) qui permettent de maintenir la position axiale dudit élément fileté (6) fixe et constante par rapport au logement (2). Des moyens de synchronisation sont aussi prévus pour permettre la rotation relative entre ledit premier élément (6) et ledit deuxième élément (3). Ladite vis se caractérise en ce qu'au moins un élément fileté présente une configuration de filetage qui permet la transmission du mouvement de rotation vers un autre élément sans action relative tangentielle de glissement.
