Viscous damper for dampening of torsional vibrations.
The Vdamp is a viscous torsional vibration damper consisting of an outer housing and an inner inertia ring, which is guided by bearing elements.They create a tight shearing gap, which is filled with high viscous silicone oil, thereby viscously coupling the ring to the housing.
The housing is mounted rigidly to the free end of the crankshaft. When the housing oscillates versus the inertia ring, an intense shearing of the silicone oil in the gap occurs. This reduces the relative movement of the two parts and in consequence is damping the torsional vibrations.The vibration energy is converted to heat which the damper conveys into the ambient air.
