    2. The gearbox according to claim 1, characterized in that the force limiter is provided with a guide with a stop for fixing the toothed rack.
    3. Gearbox opp.1 and 2, characterized in that in the hydraulic cylinder in the piston cavity also an opening for supplying fluid is made.
    This invention relates to mass engineering and can be used on drilling platforms. Known reducer with force limiter for lifting drilling platforms containing a drive, a drive shaft associated with it, a gear with a driven gear and a force limiter installed between the drive and the gear drive in the form of a hydraulic cylinder with a piston and a hole in the piston cavity ClJ. reliability of the device. The goal is achieved by the fact that a gearbox with a force limiter for lifting a drilling platform, containing a drive, a driving shaft associated with it, a gear transmission with driven gear and a force limiter mounted in the form of a hydraulic cylinder with a piston and a hole between the drive and the gear mechanism in the piston cavity is provided with a multistage gear installed between the drive and the force limiter and a brake connected to the drive, installed with a possible rotation around the drive shaft; The cylinder is fixed on the gear housing, and on the piston there is a gear rack, which is in engagement with the gear wheel mounted on: the housing of the multi-stage gear train. The force limiter is provided with a guide with a stop for fixing the ratchet. In the hydraulic cylinder in the piston bolster, there is also an opening for the supply of fluid. FIG. 1 shows a gearbox, a general view with cuts; in fig. 2 - ra cut, aa on fig. 1. The gearbox contains an electric drive 1 connected to the drive shaft 2 by means of a multistage gear train 3. The drive shaft 2 is connected to the gear train A connected to the shaft of the driven gear 5, with which the rack 6 meshes with the gearbox. the drilling platform, the Electric drive 1 has a brake 7, a gear wheel 8 is rigidly attached to the body of a multi-stage gear that is in engagement with the gear rack 9, and a gap is provided between the gear wheel 8 and the drive shaft 2. A toothed rail 9 is connected by a rod with a piston 10 of a hydraulic cylinder 11, which is a force limiter. The hydraulic cylinder 11 has a main 12 and an additional 13 apertures for the supply of fluid. A toothed rail 9 moves in a guide 14 having a stop 15. The hydraulic cylinder 11 is rigidly fixed to the gear housing 4, which, in turn, is fixed on the bracket 16 of the drilling platform. On the drive shaft 2, a gear wheel 17 is fastened, which is fixed. locking mechanism 18. The gearbox works as follows. When the actuator 1 is turned on, the latter begins to rotate the drive shaft 2 through a multistage gear transmission 3 and a gear transmission 4, the shaft of the driven gear 5 connected with the gear rack 6 fixed on the support is connected with the gearbox. In this case, the force from gear 5 through the supports is transmitted to the bracket 16, mounted on the drilling platform, and subsequently moves relative to the support. At this, electric motors with mechanical gears on all supports must synchronously operate so that there is no skew of the platform. In the event of an overload on any support, a force limiter is provided in the form of a hydraulic cylinder 11 with a piston 10 in order to avoid gear breakage. All hydraulic cylinders of one bearing are hydraulically connected to the general hydropneumatic accumulator (not shown). In order to install the pore 10 of the hydraulic cylinder 11 to its initial position, when the platform is lowered, the electric actuator 1 is turned on and supplied to the hydraulic cylinder 11 by a fluid under pressure at a pressure corresponding to the response caused by the torque of the electric actuator 5 by one stroke of the piston 10 is not enough It takes several moves. For this, a brake 7 and a locking device consisting of a gear and a locking mechanism 18 are provided. The invention allows reliably reducing to a strictly defined amount of force transmitted by the gear, and evenly distribute the forces between the various gears of the same support without breaking gears under conditions x strong pitching platform during a storm.
