Abstract

La présente invention concerne un outil de vissage/dévissage comprenant :- un moteur - un mécanisme d’impact (110, 200, 310, 410, 710, 810), entrainé par ledit moteur selon un axe de rotation (AR) et maintenu fixe en translation selon ledit axe de rotation (AR), comprenant :- un système de frappe comprenant un élément de frappe (1112, 2112, 3112A-B, 4112A-C, 7112A-D, 8112A-E), - un carré de sortie (112, 312, 412) comprenant un élément de réception de frappe (1121, 2121, 3121A-B, 4121 A-C),l’élément de frappe (1112, 2112, 3112A-B, 4112A-C, 7112A-D, 8112A-E) étant configuré pour entrer en contact avec l’élément de réception de frappe (1121, 2121, 3121A-B, 4121 A-C) pour générer un couple d’impact,ledit système de frappe étant configuré pour être entrainé en rotation, selon l’axe de rotation (AR), sur au moins 200° avant l’impact. Selon l’invention, le mécanisme d’impact (110, 200, 310, 410, 710, 810) comprend des moyens antivibratoires configurés pour que, au moins lors d’un impact, le centre de gravité (G1, G2, G4, G3, G7) du mécanisme d’impact (110, 200, 310, 410, 710, 810) soit sensiblement positionné sur ledit axe de rotation (AR), et ledit axe de rotation (AR) du mécanisme d’impact (110, 200, 310, 410, 710, 810) soit sensiblement un de ses axes principaux d’inertie.
