Dutch Fluid Power Transmission Conference 2017


AgendaCompany Ortlinghaus

• Key markets

• Basic technology

Marine technology

• Products for controllable pitch propeller applications

• Products for fixed propeller applications

Winch technology

• Products for decks machinery applications

• Products for construction machinery applications


Market due to applicationFocus on 4 major industries


Design principle of wet running clutch system

• Actuation and torque control bypressure oil on piston

• Thermal control by calculation ofcooling oil supply

• Permanently lubricated and cooledfriction material and toothing Pressure oilCooling oil

Torque transmission by hydraulically actuated plates stack


Plates stack with steel plates and coated plates

Steel plates with sinus

• Good separation and constantclearing between inner and outerplate when disengaging

Coated plates with different materials due to application

• Sintered plates

• Plates with paper linings


Functionality of wet running plate stack

Innerplate

Outer plate

Oil film betweeninner plate andouter plate

No direct contact between frictionpartners due to oil film

• Nearly no wear of frictionpartners

• Lubrication of complete clutch

• Oil film leads to idle/drag torque, which has to be calculated


Comparision wet running vs dry running

Advantages wet running

• Nearly wear free frictionmaterials

• High thermal loads permissable

…..and

• No fretting corrosion on platesor spline connections

Disadvantages dry running


Ortlinghaus supply scope for marine applications

• Hydraulic clutch

• Plate stack

• Clutch system

• on/off

• slipping function


Marine applications

Propulsion concept – Separate gearbox with hydraulic clutch integrated

Use of clutch

• Synchronization of diesel engine to propeller drive

• Engagement of PTO-/PTI-drives

• Engaging and lubrication with gearbox oil volume

• Standardized clutch components available


Marine applicationsPropulsion concept – Rudder Propeller

Use of clutch

• Synchronization of diesel engine to z-drive

• Easy installation and reduced maintenance costs

• Optional shaft brake possible


Clutch / Brake control concept

Oil from tankPressure brakePressure clutchCooling oil inCooling oil out

Oil-inlet brake clutch


Marine applicationsPropulsion concept – clutch system Prop.act MD

Use of clutch-system


• Trolling up to idle speed allows sensitive maneuverability

• Self sufficient unit (ready to use)

• Free location of standalone unit

• Also available as flangeable solution to gearbox of rudder propeller


Marine applicationsPropulsion concept – clutch system Prop.act HD for fire fighting (fifi)

Use of clutch system


• Unlimited slipping till nominal speed

• Main drive driven use of pump

• Keeping vessel position against reaction force of pump


Marine applicationsPropulsion concept – Hybrid drive, clutch onto upper gearbox or Prop.act-system

Use of clutch / Prop.act-system


• On/off clutch function for choice between different main drive options

• Disconnection of diesel drive train, when e-motor driven

• Clean cruising in restricted areas

Ortlinghaus supply scope for winch applications

• Hydraulic multi disc brake

• Plate stack

• Spring applied slipping clutch


Winch applications for decks machineryAnchor winch or towing winch with hydraulic drive

Usage

• Holds position when motor is switched off

• Mounted in front of hydraulic motor

• Spring applied multi-disc brake, hydraulically released


Winch applications for decks machineryHeavy duty rope winches for floating crane

Usage

• Redundancy, one brake on drive side and one brake on output side of winch drive

• Useful for man riding


Winches for construction machineryCrawler crane with hydraulical drive

Usage

• Spring applied holdingbrake on drive side ofwinch

• Controlled by hydrauliccircuit, lubricated bygearbox oil


Winches for construction machineryCable excavator with freefall winch

Free fall brake inside winch drum

Hydraulicmotor with

holding brake on drive side

Usage

• Brake regulates the power flow from planetary gearbox to winch drum

• Control of lowering speedvia free fall winch brake without using drive motor


ResumeApplication fields of dry running and wet running clutches and brakes

• Dry running clutches and brakes:

- Are justified for low thermal loads and low engagement frequencies

- Drive-side and output-side should produce only few vibrations

• Wet running clutches and brakes:

- Are nearly wear free and suitable for high loads and high engagement frequencies

- Are to be preferred in case of diesel engine drives
