UNBALANCE-COMPENSATING DEVICE FOR A WEAPON, ESPECIALLY A LARGE-CALIBER WEAPON WITH A LONG BARREL

An unbalance-compensating device for a weapon, especially a large-caliber weapon with a long barrel, with a component accommodating the barrel, mounted on trunnions in a stationary accommodation, and pivoting in elevation. The pivoting component's center of gravity is outside the trunnions' axis of rotation. A torque that counteracts the moment of unbalance is generated in that the weapon's pivoting component is attached by a flexible tractioning component to a device on the stationary accommodation that produces a positioning force. The tractioning component travels along a contour of prescribed shape attached to the weapon's pivoting component and determining the effective component of lifting force. The device is light in weight, takes up little space in the vicinity of the angle of elevation, and provides almost perfect compensation for the moment of unbalance while also allowing for temperature compensation. The device that generates the positioning force has a pneumatic cylinder with a piston rod attached to the flexible tractioning component and with its interior communicating with a compression reservoir.
