DRIVE OF ERASING CYLINDER FOR METALLOGRAPHIC PRINTING MACHINE Russian patent published in 2003 - IPC

FIELD: modifications of the drive of the erasing cylinder for metallographic printing machine. SUBSTANCE: in one of the modifications the drive has a drive shaft for bringing to rotation of the erasing cylinder shaft and a drive member for bringing to rotation of this drive shaft. The drive shaft and the drive member are connected to each other with an intermediate engagement of the flexibly deformable means. The drive shaft and the drive member are connected to each other with the aid of a camshaft with an intermediate engagement of a gear wheel of a flexibly deformable material, the flexibly deformable teeth of the gear wheel get engaged between every two adjacent cams of the camshaft. In another modification the drive of the erasing cylinder, the drive shaft and the drive member are connected to one another with an intermediate engagement of the flexibly deformable means. The drive shaft is made as a hollow shaft, and the drive member has a drive end entering this hollow shaft. The flexibly deformable means in the form of shock-absorbing members are installed between the outer drive end and the inner cavity of the shaft. EFFECT: reduced action of abrupt variations of torque under the load of the erasing cylinder on the drive of the erasing cylinder and kinematic chain of the printing machine motor. 11 cl, 5 dwg
