    2. The coupling according to claim 1, characterized in that it is provided with additional intermediate disks 22.
    3. Coupling POP.1, characterized in that it is provided with stops 19 for limiting the relative angular movement of the master 15 and the slave 13 disks.
    It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
    The invention relates to elastic couplings, preferably for transmitting torques from a belt pulley to the main drive shaft of a multi-color printing press. Known elastic coupling according to Germanium patent No. 618060, cl. 47 p. 5, 1935, containing drive and follower disks interconnected by springs located on the circumference, perceiving shock loads and preventing the effects of vibrations on the machine. The disadvantage of this design is that the vibrations coming from the drive motor are almost completely transferred to the main one at the water shaft of the printing press. This design is not applicable to drive printing machines due to their size. The purpose of the invention is to improve print quality by preventing duplication of the contours of the printing elements while at the same time increasing reliability. The invention is based on the task of creating an elastic coupling, with which, with soft spring characteristics and limited dimensions, high driving moments can be transmitted. This goal is achieved by the fact that the elastic coupling, mainly for transmitting torque from the pulley to the main water shaft of a multi-color printing press, contains the master and follower disks interconnected by circumferentially mounted springs, mounted between the master 15 and the slave 13 with the possibility of rotation relative to the main drive shaft 6 by the intermediate disk 21 connected to the lead 15 and driven by 13 disks by means of tangentially arranged springs 26, related to each other. The clutch is also provided with additional intermediate disks 22 and stops 19 for limiting the relative angular movement of the master 15 and the slave 13 disks. The stop 19 protects the clutch from overloads. In the proposed device, oscillations in the working area of the machine, coming from the V-belt and from the drive engine, are almost completely extinguished. This provides the possibility of transferring almost constant torque from the drive motor to the main drive shaft and the elimination of the tooth profile due to fluctuations in the rise of the tooth profiles or the reversal of the tooth profiles. Print quality is greatly improved, i.e. errors in the register are reduced and the occurrence of doubling is prevented. The use of an elastic coupling leads to a significant reduction in the load of the drive mechanism, the service life of which is increased, and the reliability of the printing machine also increases. In addition, the dimensions of the elastic coupling are reduced. FIG. 1 shows a diagram of a sheet-fed rotary press; in fig. 2. - elastic coupling, cut; in fig. 3 - attachment of springs on the eye bolu; in fig. 4 is a side view (view X); in fig. 5 - the location of the springs on the disk; Fig. 6 shows a series connection of springs. Sheet rotary printing machine (Fig. 1) contains several
    the printing units 1, the feeder 2 and the sheet-feeding device 3; Actuating is carried out by the driving motor 4 through the belts 5 to the elastic coupling 7 installed on the main drive shaft 6, the Torque of the individual printing section 1 is transmitted from the main drive shaft 6 through the gears 8 on the printing cylinder 9. The printing sections 1 are connected to the printing cylinders 9 and the transfer drums 10 by the driving wheels 11. On the main drive shaft 6 by means of a prismatic tongue 12, the drive disk 13 is attached in the form of a hub with a flange eat. A drive disk 15 is mounted on the wheel drive 14 on the wheel drive carrier 14. The belt pulley 16 is rigidly connected to the drive disk 15 and to the limiting disk 17, which is mounted on the disk 13 hub with a rotation bearing 18. The restrictive disk 17 is connected by means of the lugs 19c to the slave disk 13, while the stops 19 are provided with rubber bushings 20.
    The movement of the stops 19 in the circumferential direction in the disk 17 is limited by slots 30, the center of curvature of which is located in the center of the disk 17. Between the master 15 and the slave 13 there are intermediate disks 21 and 22, each of which is mounted through bearings 23 and 25 on the hub Slave disk 13 with the possibility of rotation.
    The drive disk 15, the intermediate disks 21 and 22, and the driven disk 13 are interconnected by means of tangentially arranged springs 26, which are connected in series with each other. The springs of the drive disk 15 are connected to the springs of the intermediate disk 21 by means of bolts 27 and eyebolts 24, the springs of intermediate disks 21 and 22 are connected by eye bolts 24, and the springs of the intermediate disk 22 and the driven disk 13 by eye bolts 24 and bolts 28 At the end The main drive shaft is fixed disk 29, locking the coupling in the axial direction.
    The clutch works in the following way.
    The torque is transmitted from the drive motor through the belt 5 to the belt tongue 16 and to the drive plate 15, then through the bolts 27 and the springs 26 to the intermediate disk 21, from which it is transmitted through the springs 26 to the intermediate disk 22 and through the springs 26 to the slave disk 13. The disks 15, 21, 22 and 13 are interconnected elastically by means of springs 26. Next, from the driven disk 13, the prismatic key 12 transfers torque to the main drive shaft 6, oscillations caused by the belts 5 or the driving motor 4, are sensed by springs 26 and extinguish. The relative angular displacement of the master 15 and the slave 13 disks is limited by the stops 19. 2i 25 22 23 ag. 2 Fig.Z28 P
