The constructive scheme of the reversible and the reverse-gear clutches.
Constructive reverse reversing – gear sleeves rotary engines with a speed of about 1500 rpm (engine RC – 19 has n 1525 rpm) can be installed on ships with underwater wings without a gearbox with one reversing muff The first towing wheeled vessel with A reversing device was built by a Russian engineer R. A. Koreiko in 1907. at Komensky machine-building plant. In the next! These years pr. Cip ero reversal was) (used in the development of most modern reversing couplings.,, The greatest spread was obtained by mechanical reversing couplings operating according to the following kinematic schemes: I. The forward firing of the disk friction, the reverse is performed by a planetary gear with conical gears Nyami D. The forward movement is activated by a disk friction, the reverse is carried out by a planetary gearbox with cylindrical gears 3, the rigid activation of the forward movement by means of syncro nizator, reverse is carried out by planetary gear with constant gears 4, rigid forward gear is engaged with a synchronizer, reverse is performed by a planetary gear with cylindrical gears 5, Friction clutch of the engine shaft with the reverse gear shaft reduces the gears of the gearbox with the cam clutch 6, the friction clutch of the front drive shafts, reversing the gear

The reversible circuit of coupling with rigid inclusion synchro forward gears and a planetary gear with bevel sestrami reverse.
By means of kesterni reversing a cam or spline coupling, a reliable coupling of the engine shaft with the coupling is ensured. Friction synchronizer is used to align the number of revolutions of the shaft of the motor shaft coupling at the time of inclusion. Due to the relatively small loads arising from the alignment of revolutions, the synchronizer is performed. is slightly affected | m number of disks or a pair of friction cones The first four types of couplings, as a rule, do not have a gearbox and are installed with engines running directly on the propeller shaft. If necessary, the clutch can be equipped with a gearbox with a lower ratio, the gearbox can be built into the clutch or be attached to it. IIx design allows you to work indefinitely in all possible modes. Power transmission at the forward and reverse gears is carried out through the gearbox, which performs the reverse function. These aufts are widely used.
for engines of small and less than average capacity (N, 5-200 Kern). Each of the six types of couplings disassembled has a large number of design options. The most typical design of the reverse – reducer of the diesel oro diesel engine (N. external shaft 4. Through gears, the rotation is transmitted to the driven shaft 11, the direction of rotation of the shaft 4. When set to the rear, the inside is turned on and 8 is opposite to the control lever

Idling corresponds to the average position of the discs 2 and 3, the engine shaft disengages the control levers 10. When disk 1 Fig. 133 shows a reversible coupling of the diesel engine (N. – 883 N6m at 1850 rpm), established as the principal in power installation of ships on underwater wings Gear ratio of revolutions of the diesel engine and the camshaft at the forward stroke: 1, at the rear i: 0.8 The main units of the reversing coupling are: the shaft of the reversing coupling, the synchronizer by a rigid cam clutch, the reversing coupling reversing gear, hydraulic manual control mechanisms. Reverse clutch shaft designed to transmit rotation from the engine shaft to the rowing engine at the front and rear of the vessel

The synchronizer reversing clutch 2 transmits rotation from the motor shaft to the shaft of the reversing clutch 1 at the front and rear passages of the vessel. In addition to Toro, he disconnects the motor shaft and the reversing coupling shaft at idle. Reducer ass “ero stroke 3 provides a change in the direction of rotation of the shaft reversing coupling when the housing is fixed

satellites. In addition, with the help of a set of gears, it helps reduce the gear ratio and, consequently, the number of revolutions of the main shaft with respect to the revolutions of the engine shaft. The main components of the gearbox are: pinion gear 4, satellite housing 5 n driven gear 9, satellite housing is rigidly connected to brake drum 6 and fingers 7, which are turned on There are three satellites 8, the reverse gear is connected to the reverse clutch 10 by means of pinion splines 4.
