Abstract

Appareil portatif (11) comprenant un arbre d'entraînement (17) pourvu d'un axe de rotation (R) et entraîné par un moteur (13) pour l'entraînement d'un outil (20), et comprenant un accouplement (30) dans l'arbre d'entraînement (17) qui comporte un premier élément d'accouplement (31) présentant plusieurs évidements axiaux qui possèdent un axe de symétrie qui est disposé sur un rayon et coupe l'axe de rotation (R), et un second élément d'accouplement (41) présentant plusieurs cames axiales qui possèdent un axe de symétrie. Les cames axiales peuvent être accouplées avec transmission de couple aux évidements axiaux par l'intermédiaire d'une surface de contact. L'axe de symétrie de chaque came axiale est disposé avec le même écartement par rapport à l'axe de rotation (R) dans une direction circonférentielle.Portable apparatus (11) comprising a drive shaft (17) provided with an axis of rotation (R) and driven by a motor (13) for driving a tool (20), and comprising a coupling (30 ) in the drive shaft (17) which has a first coupling element (31) having a plurality of axial recesses which have an axis of symmetry which is disposed on a radius and intersects the axis of rotation (R), and a second coupling element (41) having a plurality of axial cams which have an axis of symmetry. The axial cams can be coupled with torque transmission to the axial recesses via a contact surface. The axis of symmetry of each axial cam is disposed with the same spacing with respect to the axis of rotation (R) in a circumferential direction.
