CA 2608330

A bolt tightening method capable of bringing about a same effect without changing the coefficient of friction of the thread surface of a bolt as in a case where the coefficient of friction of the thread surface of the bolt is reduced to increase the axial force of the bolt provided when the bolt is tightened and a bolt tightening device capable of realizing the bolt tightening method. The bolt tightening method using the bolt having a bolt head part and a bolt shaft part with a male screw part for tightening a tightened body is characterized by comprising a step for tightening the bolt by imparting a torque for rotating the male screw part to the bolt head part in such a state that a lateral load parallel with the seat face of the bolt is imparted to the head part of the bolt to intentionally deviate, from each other, the surface pressures on the thread surface and the seat surface of the bolt provided when the bolt is tightened.

L'invention concerne un procédé de serrage de boulon capable de produire le même effet sans modifier le coefficient de friction de la surface de filetage d'un boulon lorsque le coefficient de friction de la surface de filetage du boulon est réduit pour augmenter la force axiale du boulon lors du serrage du boulon et un dispositif de serrage de boulon capable de réaliser le procédé de serrage de boulon. Le procédé de serrage de boulon utilisant le boulon ayant une partie de tête de boulon et une partie de tige de boulon avec une partie de filet mâle permettant de serrer un corps serré est caractérisé en ce qu'il comprend une phase de serrage du boulon en imprimant un couple pour faire tourner la partie de filet mâle sur la partie de tête de boulon pour conférer une charge latérale, parallèle à la face d'appui du boulon, à la partie de tête du boulon pour faire dévier de manière intentionnelle, l'une de l'autre, les pressions superficielles sur la surface de filetage et sur la surface d'appui du boulon, pressions rencontrées lors du serrage du boulon.
