    The invention relates to a device for controlling the drive in printing presses of the sectional type, namely for duplex printing machines. For double-sided printing machines, the printing sheet is gripped by a sheet-feeding cylinder from the previous cylinder at the point of contact for the trailing edge. Inside the sheet cylinder, the printed sheet is transferred to the second gripper system and then held further forward by the former trailing edge. When printed on one side, the printing sheet is grasped at the same point by a sheet-feeding cylinder at the leading edge. In order for the suction cups or the grips of the cylinder liner to hold the printed sheet once for the rear edge and once for the front edge, a corresponding phase shift must be made on the cleaning unit before or after the sheet cylinder. According to the GDR patent number 135812 Cl. In 41 F 13/24, published. 05/30/79 A device is known in which the individual printing units are driven by means of gears forming a closed kinematic chain. By introducing a double gear unit into the kinematic chain, the machine is shifted to the required phase shift. In this case, the double gear train assembly is designed so that the first gear wheel is rigidly connected to the cylinder, and the second is pressed against the first one by force of the spring, so that a connection with a force closure occurs. By means of centrally controlled screws for repositioning the drive, the force-closure connection can be removed. With this invention, drive permutation is greatly simplified. The plane-parallel compression forces between the two gears can be reproduced to the same degree after each shift of the drive. The disadvantage of the device is that before each rearrangement the cover covering the side wall must be removed. This is associated with high labor costs, and, in addition, the time of a simple machine increases. The aim of the invention is to increase the efficiency of operation of the device by reducing the time simply by changing over from one-sided to two-sided printing. The invention is based on the task of creating a device in which the drive can be retooled without spending a great deal of time on removing and re-mounting the cladding and achieving even and reproducible securing of the means providing the drive tripping. The goal is achieved in that the coupling and disengaging mechanism of the kinematic chain includes a control system and associated hydraulic elements mounted on the ring, the latter being installed between the first gear wheel and the coupling and disengaging mechanism of the kinematic chain. The hydraulic elements of the coupling and disengaging mechanism of the kinematic chain are made in the form of two or several hydraulic cylinders, each of which has a gear toothed crown connected to the first gear wheel of the coupling and disengaging mechanism by means of a gear and a pin interacting with it. The hydraulic elements of the mechanism of coupling and disengagement are made in the form of selsyn engines, the shaft of each of which is threaded, and in the first gear wheel there are threaded holes interacting with the corresponding shaft. The hydraulic elements are made in the form of hydraulic cylinders, the shafts of each of which are connected to the first gear wheel via an eccentric disk. In addition, the control system includes a hydraulic oil distributor mounted on the axle of the printing cylinder and connected to hydraulic elements equipped with running and safety valves. In addition, the device has sensors for monitoring respectively the coupling and disengagement of the gear wheels and the sensor for controlling the kinematic chain. Pa figs. 1 is a schematic diagram of a two-color sheet offset printing machine; in fig. 2 shows section A-A in FIG. one; in fig. 3 - axle print cylinder with gears, providing a permutation of the drive section; in fig. 4 - the same, side view; in fig. 5 — fastening the gear by means of a screw, a gear rack and a hydraulic working cylinder; in fig. 6 — fastening the gear by means of a screw and a hydraulic selsyn engine; in fig. 7 securing the gear by means of a hydraulic working cylinder and an eccentric disk; in fig. 8 is a section BB in FIG. 7; in fig. 9 is a schematic diagram of a hydraulic circulation circuit. The sheet to be printed is transferred from the cover drum 1 to the printing cylinder 2 and printed in the contact area between the printing cylinder and the offset cylinder 3. In the case of printing on one side, the sheet is transmitted by the front edge forward to the sheet cylinder 4, which guides it to the printing cylinder 5 second printing unit. In the area of contact between the printing cylinder 5 and the offset cylinder 6, a second ink is applied to the sheet on the same side. The sheet is then passed to the next printing station or to the acceptance. In duplex printing, the sheet after the first printing is on the printing cylinder 2 until the rear edge of the sheet is caught by the suction system (not shown) on the sheet supplying cylinder 4 at the tangent point. As the cylinder rotates further, the suction cups and the grips attached to them are folded inside the cylinder, and the rear edge of the sheet is transferred to the grippers. The sheet is guided back to the next printing unit, and the reverse side is printed. When moving the machine from one-sided to two-sided printing, it is necessary to rotate the print cylinder 2. With rotation of the printing cylinder 2, all cylinders and drive parts of the front part of the masking are simultaneously shifted relative to all cylinders and drive parts of the back part of the machine. To reposition the drive on the trunnion 7 of the printing cylinder 2, a gear wheel 9 is engaged, which engages with a gear wheel 8 of a drum drum 1. A gear wheel 11 is attached to a gear wheel 9, which has a gear with gear wheel 10 of a sheet cylinder 4. This is connected by a ring 12 by means of hydraulic elements 13 to a gear wheel 9 without the possibility of rotation. In the first exemplary embodiment of the invention (Fig. 3-5), hydraulic elements 13 are mounted on the ring 12, which are formed by four hydraulic cylinders 14. Each of these hydraulic cylinders 14 has a gear ring 16. It engages with gear wheels 17 (FIG. 5), each of which is rigidly connected to the threaded pin 18. The threaded pins 18 are screwed into the threaded holes 19 of the gear 9 and cause the tension of the gear 11 between the gear 9 and the ring 12. The hydraulic oil necessary for the operation of the hydraulic cylinders 14 is supplied through the hydraulic oil distributor 20 which is screwed into the axle 7 of the printed cylinder 2, through pipes 21 and 22. For tightening the threaded fingers 18, hydraulic oil is directed through pipe 21 on the side of the hydraulic cylinder 14, where the stem 15 is located. For unscrewing the threaded fingers 18, hydraulic oil guided through pipe 22 on the side of hydraulic cylinder 14, where there is no stem. In this case, a different value of the effective areas of the piston for unscrewing the threaded fingers 18 causes a greater torque. - The torque required to tighten the threaded fingers 18 is achieved by adjusting the pressure of the control system connected in front of the hydraulic oil distributor 20 (Fig. 9). The control system is supplied with hydraulic oil from the machine’s supply unit.
    hydraulic oil. By means of a safety valve 23, which is combined with a pressure reducing valve, the required working pressure is adjusted. A magnetically controlled flow valve 24 is connected in series with the safety valve 23, whereby the loading of the hydraulic cylinders 14 is carried out by means of pipes 21 or 22. Sensors 26-28 are mounted on the side wall 25 to monitor the condition of the connection of gear wheels 9 and 11. They work together with probes 29 fixed on the rods 15, which protrude from the hydraulic cylinders 14. When the pins 18 are unscrewed, the sensors 26 are triggered, while the closed ones are sensors 27. If the kinematic chain is interrupted, for example, due to a broken 18 s The threads 28 then operate. The sensors 28 are connected. All four hydraulic cylinders 14 are equipped with sensors 26-28 which are connected in series with each other, due to which faults are immediately indicated. To maintain the lateral clearance of the gear 11, with the threaded pins 18 unscrewed within the allowable limits between each two hydraulic cylinders 14, spacer spacers 30 distributed around the circumference are provided, which are tightly screwed to the gear 9 and conduct the ring 12 with a slight lateral clearance.
    When the hydraulic cylinders 14 are loaded with hydraulic oil, the gear wheel 17 rotates and the threaded pin 18 rotates by means of the rod 15, thereby causing the gear wheel 11 to be stressed between the gear wheel 9 and the ring 12. When the hydraulic oil 14 is opposite to the hydraulic cylinders, this voltage eliminated again.
    In the second exemplary embodiment of the invention (Fig. 6), four selsyn engines 31 are mounted on the ring 12. The shaft 32 of each selsyn engine 31 is provided with a thread on the projecting end, which is threaded into the threaded hole 19 of the gear wheel 9.
    When the hydraulic oil is injected into the selsyn engines 31, the threaded shaft 32 rotates, which leads to a tension of the gear wheel 11 between the gear wheel 9 and the ring 12. With the opposite inlet, this voltage is again eliminated.
    In the third embodiment of the invention (FIGS. 7 and 8), hydraulic cylinders 33 are fixed to the hinges on the ring 12. The shaft 34 of each hydraulic cylinder 33 is movably connected to an eccentric disk 35. The eccentric disk 35 is mounted rotatably in the bearing bracket 36, screwed with a gear wheel 9. The bearing bracket 36 is fastened in such a way that the screws 37 pass through the through holes of the ring 12 and are screwed into the threaded holes of the gear 9. By means of the screws 37, it is installed A small clearance is required for repositioning the gear 11. After installation, the screws 37 are prevented from rotating by means of the nuts 38. The bearing brackets 36 have a slot 39, into which an eccentric disk 35 enters. Hydraulic cylinders 33 are movably connected to bearing brackets 40 fixed to ring 12. When hydraulic oil is injected into hydraulic cylinders 33, disk 35 rotates through rod 34, thereby the tension of the gear 11 between the ring 12 and the gear 9. When the hydraulic oil is in the opposite direction to the hydraulic cylinders 33, the stress is again eliminated.
    Due to the use of hydraulic elements 13, it is possible to perform a drive permutation without removing the facing of the machine. In addition, both the weakening and the tension of the gear wheels 9 and 11 are carried out simultaneously and in each case with the same pressing force.
