Abstract

Stoßantrieb 1 für ein linear zu bewegendes Werkzeug mit folgenden Merkmalen: In einem Ständergehäuse 2 ist ein linear beweglicher Läufer 4 angeordnet, der ein inneres Ende 5 aufweist, das in dem Ständergehäuse 2 angeordnet ist, und der ein freies Ende 6 für ein Werkzeug aufweist. In dem Ständergehäuse 2 ist ein gasgefüllter Druckraum 13 angeordnet, wobei in dem Druckraum 13 ein Überdruck p gegenüber der Umgebung herrscht oder erzeugbar ist, der so bemessen ist, dass der Läufer 4 über den Stellweg auf eine Geschwindigkeit von mindestens 6 m/s beschleunigt wird. In dem Ständergehäuse 2 ist ein erstes Linearlager 11 angeordnet, in dem das innere Ende 5 des Läufers 4 linear geführt ist. An das Ständergehäuse 2 schließt sich ein Führungsgehäuse 3 an, in welchem ein zweites Linearlager 12 in einem axialen Abstand zu dem ersten Linearlager 11 angeordnet ist.Impact drive 1 for a tool to be moved linearly with the following features: In a stator housing 2 a linearly movable rotor 4 is arranged, which has an inner end 5 which is arranged in the stator housing 2 and which has a free end 6 for a tool. A gas-filled pressure chamber 13 is arranged in the stator housing 2, with an overpressure p in relation to the surroundings that prevails or can be generated in the pressure chamber 13, which is dimensioned such that the rotor 4 is accelerated to a speed of at least 6 m / s over the travel distance . In the stator housing 2, a first linear bearing 11 is arranged, in which the inner end 5 of the rotor 4 is linearly guided. A guide housing 3, in which a second linear bearing 12 is arranged at an axial distance from the first linear bearing 11, adjoins the stator housing 2.
