The present invention provides a hammerless mechanical attachment system (10) comprising a C-clamp member (46), a first wedge member (48), a second wedge member (50) and a threaded tensioning device (52) for attaching a tooth adapter (12) to a base cutting edge (14) of an implement that eliminates bending forces on the tensioning bolt (52) or the misalignment between the mounting holes for such tensioning bolt (52). The threaded tensioning device (52) is disposed through the bolt hole (76) in the first wedge member (48) and threadably engaged with the threaded aperture (68) in the flange (64) of the C-clamp member (46), whereby the second wedge member (50) is caused to move in a forward direction upon tightening of the threaded tensioning device (52) for securing the adapter (12) to the base edge (14).
L'invention concerne un système de fixation (10) mécanique sans marteau. Ce système comprend un serre-joint en C (46), un premier taillant (48), un second taillant (50) et un dispositif (52) tendeur fileté permettant de fixer un porte-pointe (12) à un bord d'attaque (14) de base d'un outil qui élimine les forces de flexion exercées sur le boulon (52) tendeur ou le désalignement entre les orifices de montage pour un tel boulon (52) tendeur. Le dispositif (52) tendeur est placé de manière à traverser le trou (76) d'éclissage dans le premier taillant (48) puis il est enclenché par filetage dans l'ouverture fileté (68) ménagée dans la collerette (64) du serre-joint en C (46). Ainsi, au fur et à mesure que le dispositif (52) tendeur fileté est resserré, le second taillant se déplace vers l'avant de manière à fixer l'adaptateur (12) au bord (14) de base.
