HOISTING GEAR OF TURRET GUN WEAPON Russian patent published in 2013 - IPC F41G5/14 

FIELD: transport.

SUBSTANCE: device is placed in gun carriage outside inhabited pert of turret gun. The carriage contains gearhead of hoisting gear, weapon guidance drive made as screw gear consisting of screw and nut. Here the nut is connected with gun carriage, screw is connected reducing gear and has kinematic connection with motor shaft forming electromechanical drive, and manual drive is made with mechanism of its automatic disabling when motor is operational. Kinematic connection of electromechanical drive is made as stepping down reducing gear consisting of gear wheel rigidly linked with screw, other gear wheel rigidly linked with motor shaft, and idler gearwheel between them. Nut is connected with gun carriage, and reducing gear is connected with turret gun body via hinged bearings.

EFFECT: reduced mass moment of inertia in kinematic chain of electromechanical drive and reduced freeplays in kinematic chain between place of screw connection with actuating element and the motor.
