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

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
DFPTC is een initiatief van
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
DFPTC is een initiatief van
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
DFPTC is een initiatief van
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
DFPTC is een initiatief van

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
