Propulsion technology - Marine technology | Ortlinghaus
Marine clutches serve to transfer power, synchronize, and separate the main and auxiliary drives. The main clutch is responsible for synchronizing the drive unit and the propeller when turning.
With the right setup, our multi-plate clutches can be used in trolling mode to enable a continuous speed adjustment between drive and output. Other applications include Power Take-off (PTO) and Power Take-in (PTI) clutches which can be switched on or off to operate additional pumps and generators.

Hydraulical clutch | Series 002/021/202
Hydraulically actuated multi-plate clutch
Based on our friction linings, which have been tried and trusted for many years in the marine sector, clutches in this series reconcile high torque and thermal absorption rates as well as a favorable outer diameter. A high shaft diameter can also be used. Due to their broad power spectrum, smaller sizes can be achieved with corresponding weight and cost benefits, especially in higher torque ranges. The optimized outer diameter makes shorter distances between axles possible, and in this way offers clear savings potential in the gearbox.
The hydraulic multi-plate clutch impresses with its comprehensive service friendliness. The plate pack, which is wear-free under the specified conditions, can be accessed from either side depending on the model, and ensures an easy, safe, and swift replacement of the plate pack. The special design also ensures that other components cannot fall out during replacement.
The Ortlinghaus muti-plate clutches safely accelerate even large propellers and generators. This optimal further development of our tried-and-tested technology sets today’s industry standards.

Prop.act
Self-sufficient hydraulically actuated clutch system
Prop.act – our new shifting clutch system is a hydraulically actuated, wet-running clutch unit. It is a stand-alone system, wich is bottom mounted. Within the drive train it can be connected between two shaft ends of the cardan shafts for example.
Prop.act impresses with a series of technical innovations and advantages, which make it efficient and economical to use.
The Prop.act clutch system can be applied in hybrid propulsions between the E-engine and the diesel engine for example. In this case the power take off can't be used because a stand by pump has to be installed.
Essential Advantages:
Efficiency
Prop.act is a sophisticated end-to-end system, which, for example, allows complete installation of the rudder propellers in the ship. The clutch system is fixed to the ships bottom as a stand-alone solution.
Wet-running
The wet-running of the clutch ensures wear-free operation (within defined technical limits).
Integrated oil supply
The supply of pressure oil and cooling oil is integrated with a built-in oil tank. As a result, no separate pumps, valves and heat exchangers are required, which makes additionally piping and expensive installation superfluous. Cabling due to shipping standard.
Definitions
Defined drive interfaces enable simple assembly of the driveshaft through adjusted connection dimensions.
Noise
The operation of Prop.act generates little noise.
Integrated sensors
Built-in sensors produce all necessary signals for operation and monitoring. This eliminates the need to install additional sensors and makes overall installation much easier.

Hydraulical brake | Series 022
Hydraulic multi-plate brakes
The 022 series is one of the most successful Ortlinghaus products. Well over one million units are in service around the world wherever safety brakes with an extremely long service life and quality without compromise are required. In marine engineering, these multi-plate brakes are used in the deck machinery sector and as shaft brakes.
The advantage of these wet-running, hydraulically released and spring-applied multi-plate brakes is the high torques they achieve in compact dimensions. Hydraulically actuated brakes are also available as a special version.
The spring-loaded brakes are safety brakes, which automatically work in cases of pressure failure. The brakes can achieve full torque even when there is no pressure.
- Torque: 100 - 30,000 Nm
- Rotations per minute: 6,570 - 450 min-1
- Outside diameter: 83 - 910 mm
- Bore diameter: 18 - 350 mm
- Length: 59 - 360 mm

Main drive - Propulsion technology
Ortlinghaus offers different engagement possibilities to connect the main drive to a gear box, respectively propeller. For the hydraulically actuated engagement clutch there exist three different supply modes. Either just a plate stack can be used in a given gear box design, or a plate stack including the engagement unit, respectively the complete clutch including housing can be offered. Alternatively a combined unit consisting of an engagement clutch together with a flexible coupling can be installed directly to the motor flange. The advantage of this unit is an additional damping of the motor vibrations.
Beside the main engagement clutches PTO and PTI clutches are also available in a wide torque range.
The determination of the clutches is proven by thermal calculations, that require certain cooling oil amounts to allow a safe operation for each mode.

Plate stacks
Wet-running sinter-lining plates
For dry- and wet-running clutches and brakes, Ortlinghaus is able to provide a very comprehensive range of plates. The plates and the friction surface are important functional elements in every clutch and brake, and have been developed in many different ways since the early days of clutches and brakes.
The choice of friction system depends on the application: in general, one plate with friction material works together with a counterplate of steel or cast iron. The inner and outer plates are mounted with the other drive components by lugs and slots, and the spline is in accordance with DIN 867 and DIN 5480 as well as other standards. In addition, holes in the plate for studs and special shapes in accordance with customer requirements are available.
Combined with a multi-plate clutch or brake, these plates come in a multitude of different dimensions, friction combinations, and surface patterns.
- Torque: 150 - 1,600,000 Nm
