Patent number: 8479633Abstract: A mechanism or drive (100) for a weapon is described, which is characterized by only a limited acceleration of the breech (20) and a jerk- and recoil-free operation, thereby reducing the inertia force and the required power and increasing the repetition rate. The reduction of the required power also results in a reduction of braking power in the case of a quick stop. For this purpose, the rotational motion of preferably a motor (50) or the like is converted to a forward or reverse motion of the breech (20) using the Scotch yoke principle. In order to allow rest periods of the breech in the end limit positions, the rod (3) and the yoke (1) are arranged radially and displaceable relative to each other so that the yoke radius changes when the yoke (1) is rotated. A control cam (6) radially guides the rod (3).Type: GrantFiled: June 3, 2011Date of Patent: July 9, 2013Assignee: Rheinmetall Waffe Munition GmbHInventors: Ralf-Joachim Herrmann, Klaus Lawitzke, Heiner Schmees, Berthold Baumann

Patent number: 8413565Abstract: A drive, having a quick stop mechanism, for a breech is axially adjustable relative to a weapon barrel, and includes a motor, two counter-rotating chains and sprocket wheels that guide the chains. Engaging cams and control cams are integrated into the chains. A slide mounted at the bottom of the breech is displaceable transversely to the direction of fire and has a groove that the engaging cams engage to entrain the breech in a forward or reverse motion relative to the direction of fire. The engaging cam transporting the breech forwards is displaced from the groove while the control cam displaces the slide simultaneously to its center position via its ascent ramp, thereby allowing breech rest periods in the forward limit position. Firing causes the slide to move from the center position to the left hand side whereas it remains in the center position when no shot is fired.Type: GrantFiled: June 6, 2011Date of Patent: April 9, 2013Assignee: Rheinmetall Waffe Munition GmbHInventors: Ralf-Joachim Herrmann, Klaus Lawitzke, Heiner Schmees, Berthold Baumann

Patent number: 8402874Abstract: A drive for a breech/breech carrier renders it axially adjustable relative to a weapon barrel. The drive includes a motor, two engaging cams mounted on a chain arranged below the breech and guided around two sprocket wheels. A slide is mounted in a guide at the bottom of the breech/breech carrier so as to move at a right angle to the direction of fire, with a groove extending over its entire width. The respective engaging cam entrains the breech in forward motion relative to the direction of fire, or in reverse motion, once the shot is fired, and transports the breech forwards, is displaced from the groove, and moves backwards without the breech, thereby allowing breech rest periods in a forward position. During firing, the slide moves, whereas it remains stationary when no shot is fired so no further engaging cam can entrain the breech backwards.Type: GrantFiled: June 6, 2011Date of Patent: March 26, 2013Assignee: Rheinmetall Waffe Munition GmbHInventors: Ralf-Joachim Herrmann, Klaus Lawitzke, Heiner Schmees, Berthold Baumann
