Title (EN) QUICKLY MOVABLE ELASTICALLY ENGAGING SCREW-AND-NUT MECHANISM
(FR) MECANISME A ECROUS ET VIS A PRISE ELASTIQUE ET DEPLACEMENT RAPIDE
Abstract: front page image
(EN)A new type of screw-and-nut mechanism comprises a supporting seat, one or more semi-nuts and the actuating means thereof, characterized in that the engagement of internal thread on the semi-nut with external thread on the screw is started elastically, then completed and locked by a positive element, and that the disengagement thereafter of the related elements is accomplished positively. Such a mechanism can be used in various kinds of jacks, vices, sliding tables of machine tools, as well as other devices which is driven by a screw and desired to pass through its return travel quickly.
(FR)L'invention concerne un nouveau type de mécanisme à écrous et vis comprenant un siège de support, un ou plusieurs demi-écrous et leurs moyens d'actionnement, qui se caractérise en ce que la prise du filet interne du demi-écrou avec le filet externe de la vis s'effectue de manière élastique, le verrouillage étant assuré directement par un élément actif, et en ce que la libération des éléments concernés est assurée de manière directe. Ce mécanisme peut être utilisé dans divers types de vérins, d'étaux, de tables coulissantes de machines outils, ainsi que d'autres dispositifs qui doivent revenir rapidement dans leur position initiale.
