    (54) SHIP'S TRANSFER
    one
    Iyobregion relates to shipbuilding, and more specifically to the design of ship gears switched from working to quiet with a smoothly controlled number of revolutions of the propeller shaft.5
    The weight of the ship's gear is containing the drive shaft, the clutch: two brakes and two planetary gearboxes, the primary part of the clutch is connected to the drive shaft, and the second part is rigidly connected to the carrier of one of the gearboxes, and kinematically connected to the driven shaft by means of intermediate shaft and gear L1 .15
    In such a way, the bosgoit range of speeds from a set of constant speeds with a stepped switch / hobby, which allows them to be continuously adjustable only by changing the speed of rotation of the drive shaft, e. Engine, which is not economical and reliable. maneuvering in port.
    The purpose of the invention is to increase the efficiency and safety of maneuvering in the port by ensuring the operation of the ship's engine at constant economic speeds and obtaining the speeds of the output shaft. This goal is achieved by the fact that the transmission is equipped with a hydraulic motor, hydraulically communicated with a hydraulic pump with an adjustable flow, and the sun mjectern of the first gearbox is connected with. By means of a hollow shaft brake, the planetary gears are enclosed by a parasitic one that has external teeth coupled to that located on the wa-. a gear motor, one of the half-bodies}) T of the clutch is additionally rigidly connected by a register to the shaft passing through the hollow shafts of the gearboxes connected to the carrier of the second planetary gearbox, the sun gear of which is connected to the second brake via a hollow shaft and the planetary gears covered with parasitic nipples with gear, 1shock5ptseys on the hydraulic pump shaft. The introduction of a hydraulic drive linking the two planetary gearboxes allows a smooth change in the rotational speed of the driven shaft at a constant rotation of the drive shaft and, in addition, significantly reduces energy losses due to good heat removal from the hydraulic circuit. The drawing shows a diagram of the ship transfer. The ship gear contains a drive shaft I, which is connected with a diesel engine by means of a highly elastic coupling, shaft 2 (not shown). The drive shaft 2 is rigidly connected to the primary part 3 of the clutch 4, to the secondary part 5 of which is connected a hollow shaft 6 carrying an intermediate gear 7, which is in gear with the larger gear 8 on the driven shaft 9 of the drive. The driven shaft 9 is secured by means of the thrust bearing Yu to receive the screw stop due to the axial stroke. Through the primary part 3 of the clutch coupling 4, the drive shaft is conducted through short lengths of hollow II and 12 of the first 13 and second 14 planetary gear and is rigidly connected by the planetary rib 15 of the second planetary gear 14. The first planetary gear 13 is connected to the secondary part 5 of the clutch 4 by means of a planetary rib 16 of the first rolling mechanism. On the planetary rib 16 there is a planetary gear 17, which is covered by a parasitic gear 18 with an external thread 19. On a segment of a hollow shaft 11, reversible to the first planetary mechanism 13, there is a sun wheel 2O on the other side, and a brake disk on the other side 21 brakes 22. At the second planetary mechanism 1 on the planetary rib 15 also finds from the planetary gear 23, which is covered by the parasitic gear 24, having an external thread 25, and the solar wheel 26 on the hollow shaft section 12, which also carries the brake disk 27 second About the brakes 28. Parasitic gear 24 through its external gear cutting 25 and the small gear 29 transfers rotation to the drive shaft 30 of the hydrostatic transfer pump 31, which is connected to the hydrostatic engine 34 by pressure. The shaft 35 of the engine of the hydrostatic pump 34 carries the small gear 36 which is in engagement with the outer toothing 19 of the parasitic gear 18. Pressure air required for switching the clutch 4 can be supplied through the shaft 37. With the clutch 4 connected, i.e. The operating stroke, as well as with the decreasing working stroke, the transmitted torque occurs through the elements 1-9. When the diesel engine reaches the minimum speed, the clutch 4 is disconnected, the second brake 28 of the second planetary mechanism 14 and the sun gear 26 disappears. The hydrostatic pump 31, which turned at that moment, transmits its full feed and thereby drives the hydrostatic engine 34 with a relatively large speed, and the individual transmission elements of the drive so consistent with each other (or may be so consistent with each other) that when switching ship's drive, i.e. When the clutch 4 is disengaged, a stepless transition corresponding to the number of revolutions is created. In slow motion, along with brake 28, brake 22 is also connected, which clamps sun gear 2O of the first planetary mechanism 13, so that the torque received from the hydrostatic engine 34 through gear 36 on the parasitic neck is transmitted through the planetary wheel 17 to the planetary rib 16. The latter drives the secondary part 5 of the clutch, the hollow shaft 6 and, finally, the driven shaft 9. By reducing the delivery volume of the hydrostatic pump 31, it is possible to control smart scheni hydrostatic number of revolutions of the engine 34 and therewith the output shaft 9 to stop. j Conversely, it is possible to gradually increase the number of revolutions of the driven shaft 9 from the stop position until the output shaft 9 reaches the switching speed, after which the brakes 22 and 28 are released and the clutch 4. is activated. The hydrostatic pump 31 is then moved to the zero position and holds,
