ANTIAIRCRAFT MOUNTING Russian patent published in 2006 - IPC F41A27/00 

FIELD: military equipment, in particular, antiaircraft mountings.

SUBSTANCE: the antiaircraft mounting is provided with a precision or superprecision drive mechanism of the training angle-data transmitter. The mechanism of one type has a vertical rod located with a clearance in the central through hole and two couplings each made in the form of a rectilinearly-contact coupling or a coupling with a flexible plate. The mentioned mechanism may also have a third double-slider coupling connecting the shaft of the rotor of the training angle-data transmitter to the vertical shaft providing for unloading of the rotor shaft of the angle-data transmitter. The vertical rod may be made in the form of a tube for connection of the hydraulic systems of the fixed and rotary parts of the antiaircraft mounting. The precision mechanism of the other type has two polyhedrons projected onto the horizontal plane in the form of two similar regular polygons. The larger polyhedron coaxial with the race has vertical faces turned inwards. The faces of the smaller polyhedron located inside the larger polyhedron are turned outside - to the faces of the larger polyhedron. The vertical geometric axle of the smaller polyhedron is fixed by bearings in a carriage resting on the radial guide along which the radial motions of the carriage and smaller polyhedron are provided up to the stop of one of the vertical faces of the smaller polyhedron against the respective face of the larger polyhedron. At rotation of the rotary part of the antiaircraft mounting the vertical faces of the smaller polyhedron alternately slide on the faces of the larger polyhedron at an invariable angular position of the smaller polyhedron relative to the larger polyhedron. The smaller polyhedron is coupled to the rotor of the training angle-data transmitter by means of the double-slider coupling. The training angle-data transmitter may be fastened on the carriage, rotary or fixed part of the antiaircraft mounting. The radial guide of the carriage is installed on the rotary or fixed part of the antiaircraft mounting, and the larger polyhedron is rigidly fastened on the fixed or rotary part of the antiaircraft mounting respectively. The cables and the dog are led to the rotary part through the free space inside the larger polyhedron not occupied by the carriage.

EFFECT: enhanced accuracy of weapon training due to attainment of the precision or superprecision level of accuracy of the drive mechanism of the training angle-data transmitter.
