Abstract

La présente invention concerne un dispositif de vissage à impact comprenant : un moteur muni d’un rotor ;un mécanisme d’impact comprenant :un élément d’inertie apte à être entrainé en rotation par ledit rotor pour emmagasiner de l’énergie cinétique au cours de phases successives d’accélération ;un arbre de sortie apte à entrainer en rotation un élément à visser. Selon l’invention, ledit dispositif comprend des moyens de transmission progressive audit arbre de sortie au cours de phases successives d’impact de ladite énergie cinétique emmagasinée par ledit élément d’inertie. Fig. 1The present invention relates to an impact screwdriving device comprising: a motor provided with a rotor; an impact mechanism comprising: an inertia element capable of being rotated by said rotor to store kinetic energy during of successive acceleration phases; an output shaft capable of rotating an element to be screwed. According to the invention, said device comprises means for progressive transmission to said output shaft during successive phases of impact of said kinetic energy stored by said inertia element.
