Title (EN) COUPLING BETWEEN TWO BODIES
(FR) ACCOUPLEMENT ENTRE DEUX CORPS
Abstract:
(EN) The invention relates to a coupling between a first body (1) with a hole and a cylindrical end zone of a second body (2) to be inserted therein, in which hole extend elastically deformable tongues (7), the free end edges of which tongues lie on a circle, the diameter of which is smaller than the outer diameter of said end zone, which tongues bend in the insertion direction when said end zone is inserted and scrape over the surface thereof with their free edges such that after inserting the end zone over some distance the movement in backward direction is blocked. The end edges (9) of the tongues have an inclining position corresponding to a part of a helix, so that during a relative rotation of the two bodies the form of the helix is followed whereby an axial relative movement also occurs and the end zone can be removed from the hole.
(FR) L’invention concerne un accouplement entre un premier corps (1) avec un trou et une zone d’extrémités cylindrique d’un deuxième corps (2) à introduire à l’intérieur, des languettes élastiquement déformables (7) se prolongeant dans ledit trou, les bords des extrémités libres desdites languettes étant disposées sur un cercle dont le diamètre est plus petit que le diamètre externe de ladite zone d’extrémités, lesdites languettes se pliant dans le sens d’insertion quand ladite zone d’extrémités est insérée et racle sur sa surface avec leurs bords libres de façon que, après l’insertion de la zone d’extrémités sur une certaine distance, le mouvement vers l’arrière soit bloqué. Les bords d’extrémités (9) des languettes ont une position inclinée correspondant à une partie d’une hélice, de façon que, pendant une rotation relative des deux corps, la forme de l’hélice soit suivie. Ainsi, un mouvement axial relatif a aussi lieu et la zone d’extrémités peut être retirée du trou.
