TANK GUN Russian patent published in 2003 - IPC

FIELD: guns of tanks and self-propelled mounts, in particular, means for installation of the gun in the turret. SUBSTANCE: the front cradle slide guide support is made in the form of an annular insert, whose inner surface is formed by two cylindrical surfaces, one of which, with a smaller radius is shifted downwards in the vertical. The rear cradle slide support is made in the form of separate segments rigidly fastened on it. Radial flexible play-removing devices engageable with the barrel are installed in the upper part of the cradle. Journal bearing races are provided with flexible rollers installed as interference fit, and with annular stops installed with a radial clearance lower of the value of elastic deformation of the rollers. EFFECT: enhanced accuracy of fire of the tank gun due to elimination of random shifts of the barrel relative to the turret, as well as enhanced rigidity of coupling of the barrel with the cradle and of the cradle with the turret. 3 cl, 8 dwg
