The Geislinger Damper – the ideal choice to deal with Torsional Vibrations

Today’s drivetrain systems have to deal with several challenges, influencing the dynamic behavior and the torsional vibrations of a system.

These include:
  • Multi-fuel-operation (e.g. Diesel and Gas)
  • Increased power density
  • Tight installation space
  • Transient operating conditions (e.g. barred speed range operation, ice impact, dynamic hybrid systems)
  • Various power curves: normal running, heavy running (in rough sea), light running
  • High torsional vibration amplitudes
  • High temperatures
  • Restrictions due to class rules

With the Geislinger Damper and our long-lasting experience, we take the challenge of any torsional vibration issues and make your powertrain a solid running drivetrain system. The Geislinger Damper efficiently reduces engine exited torsional vibrations and therefore protects crankshafts, camshafts, intermediate shafts, propeller shafts and other driveline components.

How does the Geislinger Spring Damper work?
The elastic damper springs split the vibratory resonance into two amplitudes and the damper mass, as well as the spring design, moves the resonance out of the critical frequency range, as shown in figure 1 below. In addition, high damping of pressurized oil reduces the amplitude of the vibration. Through precise Torsional Vibration Calculation (TVC) with our in-house software and analysis by our experienced TVC engineers, the Geislinger Damper is perfectly customized to your specific powertrain system. This enables a highly effective and compact design with constant product properties throughout the lifetime of your system.

Our new animation video of the Geislinger Damper gives you an insight into the principal function of the Geislinger torsional vibration damper. The damper is mounted at the free end of the crankshaft. You can see how the cylinders in action cause torsional vibrations, which are reduced by the damper. This happens due to the movement of the fatigue resistant steel springs, depending on the combination of spring design and rotating inertia. The hydrodynamic damping is created by the movement of the oil through the chambers on each side of the springs. For more than 60 years’ the Geislinger Damper has been a proven high-end technology which improves the lifetime of various systems and successfully decreases the total cost of ownership due to its long service life. Partnering with Geislinger, customers can rely on a tailor-made product which is the best fit for each application, while optimizing the overall propulsion system. Learn more:
