Abstract

La douille de serrage est partagée sur sa périphérie, en zones de serrage 1 et en zones de déformation 2. Les zones de serrage comportent un filetage en dents de scie 7 tandis que les zones de deformation 2 comportent des fentes 3 disposées en sens inverse et, commençant sur un bord de la douille et s'étendant presque jusqu'à l'autre bord où elles se terminent par un arrondi 4. L épaisseur de la zone de serrage est supérieure à l'épaisseur de la zone de déformation On obtient une déformation régulière et concentrique de la douille de serrage.
