    It contains a friction clutch (4) in the drive line between marine engine (2) and marine propeller (8). A device (10) controls the clutch pressure as a function of a maximum permissible control power of the friction clutch (4) during its slip phase in such a way that the maximum permissible control power is not reached or is not reached before the end of the slip phase. Reduction of the engine speed below a certain minimum value during the closing of the clutch is prevented by the predetermined slip phase. At the same time, the clutch is prevented from being overloaded by overheating in the slip phase. <IMAGE>

    The invention relates to shipbuilding, a ship propulsion system with a ship engine, which is connected to the propeller by means of a friction clutch.
    The aim of the invention is to increase reliability by avoiding overloading the friction clutch due to too much work to: switch, and at the same time prevent the engine from retracting or excessively reducing the engine speed with a correspondingly heavy load with the propeller of the vessel.
    Figure 1 schematically depicts 4: idle power installation; in fig. 2 is a diagram showing the change in the value of the maximum allowable operation when switched on depending on the slip time of the clutch and illustrates the actual work done when switching on in relation to the maximum allowable work at switching on.
    The ship propulsion system (Fig. 1) includes the ship engine 1, which, through a switchable friction clutch 2 and gear 3, drives the propeller 4. The device4

    Control 5 through the speed sensor 6 takes into account the number of turns at the input, and with the help of the sensor, the number of turns, the number of turns at the output of the friction clutch 2, as well as using the strain gauge 8 fixed to the input shaft of the friction clutch 2 friction clutch. - The result of a measurement using a tachometer on the input shaft of the friction clutch 2 gives a rotational speed value that coincides with both the damping of revolutions at the input of the friction clutch and the engine speed of the ship engine 1 Depending on the sensor readings 6-8 computing unit of control unit 5 calculates the corresponding work performed when the friction clutch 2 is turned on. Next, the computing unit of the control unit 5 transmits to the memory block the value of the maximum allowable operation when the friction clutch 2 is turned on. The comparator compares the work performed when switching on with the maximum allowable work when switching on and controls or adjusts, by means of valve 9, the switching pressure of the friction clutch 2. At the same time, using the valve 9, the flow of working fluid from the source is controlled or regulated accordingly. 10 pressure to friction clutch 2.
    In the diagram (Fig. 2), the time t is indicated horizontally, and the work when A. is turned on vertically. The curve shows the maximum allowable operation when the friction clutch is turned on, depending on the slip time of the friction clutch. From this it follows that the maximum, permissible operation when the clutch is engaged is not a constant value, but depends on the total slip time. The value of the maximum allowable slip work can only be achieved at the end of the slip slip phase, but not during the slip phase. The curve shows the upper limit value of the load of the friction clutch 2, the lower limit value is provided by

    power of the ship engine. If the power of the ship's engine, for example, when starting off, is not sufficient to continuously increase the speed of the propeller 4 to a value corresponding to the minimum number of revolutions of the ship's engine, the clutch pressure is controlled or adjusted by the device so that the engine speed is not goes over the allowed minimum value.
    In the same way, a decrease in the engine speed below the acceptable minimum value is prevented by controlling or controlling the clutch pressure, if the resistance of the propeller 4 is up to, with high values, for example, when ice gets in during movement on icy water.
