PROCÉDÉ DE FABRICATION D'UN ASSEMBLAGE VISSÉ À SERRAGE MÉCANIQUE ET ASSEMBLAGE VISSÉ POUVANT ÊTRE SERRÉ AVEC UN BOULON FILETÉ ET UN ÉCROU
Abstract:
(DE)
Bei dem Verfahren zum Herstellen einer mechanisch, insbesondere hydraulisch spannbaren Schraubverbindung mit einem Schraubbolzen (20) und einer ein Mutterngewinde aufweisenden Mutter (38), wird ein Schraubbolzen (20) mit einem vorgegebenen Schraubengewinde (22) hergestellt. Anschließend wird der Schraubbolzen (20) in einen vorgegebenen, gedehnten Zustand gebracht. Dann wird das Schraubengewinde (22) in dem vorgegebenen, gedehnten Zustand in seiner genauen Geometrie erfasst und ein Abbild (34) erstellt und wird das Mutterngewinde (36) als möglichst exakte Kopie des Abbilds hergestellt. Die hydraulisch spannbare Schraubverbindung hat einen Schraubbolzen (20) mit Schraubengewinde (22) und eine Mutter (38) mit Mutterngewinde (36). Das Mutterngewinde (36) ist eine Kopie eines Abbilds des Schraubengewindes (22), welches Abbild von dem Schraubengewinde (22) in einem Zustand erhalten wurde, den das Schraubengewinde (22) in einem vorgegebenen, gedehnten Zustand des Schraubbolzens (20) hat.
(EN)
In the method for producing a threaded connection that can be tightened mechanically, in particular hydraulically, the threaded connection having a threaded bolt (20) and a nut (38) having a nut thread, a threaded bolt (20) having a specified screw thread (22) is produced. The threaded bolt (20) is subsequently put into a specified elongated state. Subsequently, the exact geometry of the screw thread (22) is detected in the specified elongated state, an image (34) is created, and the nut thread (36) is produced as a copy of the image that is as exact as possible. The threaded connection that can be tightened hydraulically has a threaded bolt (20) having a screw thread (22) and a nut (38) having a nut thread (36). The nut thread (36) is a copy of an image of the screw thread (22), which image has been obtained from the screw thread (22) in a state that the screw thread (22) has in a specified elongated state of the threaded bolt (20).
(FR)
L'invention concerne un procédé de fabrication d'un assemblage vissé à serrage mécanique, en particulier hydraulique, comprenant un boulon fileté (20) et un écrou (38) présentant un filetage, lequel permet de fabriquer un boulon fileté (20) avec un filetage (22) prédéfini. On amène ensuite le boulon fileté (20) dans un état d'allongement prédéfini. Puis on relève la géométrie précise du filetage (22) dans l'état d'allongement prédéfini et on crée une reproduction (34) pour fabriquer le filetage d'écrou (36) sous la forme d'une copie la plus exacte possible de cette reproduction. L'assemblage vissé à serrage hydraulique présente un boulon fileté (20) avec un filetage (22) et un écrou (38) avec un filetage (36). Le filetage d'écrou (36) est une copie de la reproduction du filetage de vis (22), cette reproduction ayant été obtenue à partir du filetage de vis (22) dans un état que le filet de vis (22) présente dans un état d'allongement prédéfini du boulon fileté (20).
