ABSTRACT:
A three rack and double pinion weapon elevation mechanism is disclosed and is useful for positioning and balancing a weapon, such as a cannon, on a combat vehicle. Two hydraulically-actuated gear racks are in facing relation with a main pinion in meshing engagement therebetween. The main pinion is integral with a shaft to which an output pinion is attached. Rotation of the main pinion produces an identical rotation of the output pinion. The output pinion is in mesh with a sector gear attached to the weapon. The two racks are slidable past the main pinion causing it and the output pinion to rotate in one direction or the other, producing a corresponding elevation or depression of the weapon. A third hydraulically-actuated rack is meshed with the main pinion to exert an elevating torque on the output pinion counter to a depressing torque exerted thereon by the weight of the weapon and which varies with changes in weapon elevation angle. A hydraulic accumulator arrangement pressurizes the third rack against the main pinion as a function of weapon position to automatically counter the depressing torque exerted by the weapon, thereby balancing the weapon on the combat vehicle.
