Abstract

L'invention concerne un dispositif pour la fixation amovible d'une dent de fouille sur un support La dent 21 est engagée par une douille 22, sur le support 23; elle est assujettie par l'engagement dans des perçages coïncidants, d'un élément de jonction 26, formé par un élément en caoutchouc 28, encastré entre deux pièces métalliques 27 et 29; selon l'invention, la pièce 27 est conformée pour que ses ailes 27c viennent buter contre les bords 33 des perçages de la douille 22 avant que la compression de l'élément en caoutchouc 28 ne le soumette à une contrainte dépassant sa résistance d'endurance. L'invention est applicable par exemple aux dents amovibles des excavateurs.The invention relates to a device for the removable fixing of a digging tooth on a support. Tooth 21 is engaged by a bush 22, on support 23; it is secured by the engagement in coincident bores, of a junction element 26, formed by a rubber element 28, embedded between two metal parts 27 and 29; according to the invention, the part 27 is shaped so that its wings 27c abut against the edges 33 of the bores of the sleeve 22 before the compression of the rubber element 28 subjects it to a stress exceeding its endurance resistance . The invention is applicable for example to removable teeth of excavators.
