The Geislinger VDAMP® and VDAMP®XT are viscous dampers that protect engine camshafts and crankshafts from possible damage caused by torsional vibrations and help to avoid barred speed ranges. The vibration energy is converted into heat, which then dissipates from the damper’s surface into the ambient air. Due to the improved Geislinger calculation method, the viscous damper can be perfectly fitted to any individual applications.
The Geislinger VDAMP® and VDAMP®XT protect engine camshafts and crankshafts from damage caused by torsional vibration and help to avoid barred speed ranges. The VDAMP® is a viscous torsional vibration damper consisting of an outer housing and an inner inertia ring, which is guided by bearing elements. Between them, they form a narrow gap, which is filled with high viscous silicone oil, coupling the ring mechanically to the housing by shearing the oil in between.
The sophisticated bearing material improves the reliability of this damper. Furthermore, the Geislinger VDAMP® is appreciated by customers as a cost-effective solution for less demanding applications. In-house oil analysis at Geislinger ensures fast response and lifetime forecasts.
Decades of experience in the field of torsional vibrations and sophisticated torsional vibration calculation (TVC) software enable customized viscous damper calculations. In order to improve the heat dissipation and extend lifetime, fins can be implemented into the housing design of the damper or an oil spray cooling can be added. Both methods improve the cooling of the damper and therefore help to increase service life.
The Geislinger VDAMP® is designed to deliver the maximum level of performance under all circumstances. Every damper is tailored to the specific requirements of your application. Ferries, dump trucks, excavators, diesel locomotives and many other applications rely on the Geislinger VDAMP®, which can be adjusted to different requirements of 2- and 4-stroke engines as well as various industrial applications.
VDAMP® for Wind Turbines:
With vast improvements in the aeroacoustics blade design over the past years, the mechanical noise of the wind turbine is becoming more and more audible. Together with the growing sizes of onshore turbines, more stringent regulations, and low wind speed operations, drivetrain noise and tonality has become more challenging. Geislinger VDAMP®, a broad-band torsional damper, gear-integrated or attached to the rotor of a direct-drive turbine, dampens torsional excitations caused by gear teeth mesh, respectively at the pole transition. The torsional vibrations causing the structure-borne noise, which is transferred to the entire wind turbine structure, are dampened effectively at their origin. Wind turbine tonalities can be avoided, and overall sound pressure is reduced.
