Damper

What are we providing for:

The Geislinger damper is capable of adjusting the natural frequency of a system and of reducing torsional vibrations. It reliably protects crankshafts, camshafts, intermediate shafts and propeller shafts from all kinds of reciprocating machines.

By eliminating the critical frequency, the Geislinger damper also helps to avoid a barred speed range.

It is most commonly mounted at the free-end of the crankshaft and consists of a primary and a secondary section. Between these, groups of leaf spring packs are arranged. These spring packs, together with intermediate pieces  form chambers which are filled with pressurised engine oil.

The elasticity is determined by the shape and the number of springs. Thereby the torsional system is tuned and the most critical resonance damped. If the exterior section vibrates in relation to the inner one, the leaf springs are bent and the pressurized engine oil is pumped from one chamber into another. This reduces the relative movement of the two parts and thus damps down the torsional vibrations.

As modern engines tend to create more than one critical frequency, Geislinger also provides dual damper solutions. This guarantees the best solution for every engine.
