Description

Torsional vibrations in piston-engine crankshafts are generated by the crank throws, which convert linear reciprocating piston movement into rotational movement. The vibration amplitudes superimposed on uniform rotation of the shaft can reach levels, both in the zones of resonance and on their flanks, which generate unacceptable stresses or at the very least undesirable noise. The viscous damper has proved successful for many years in reducing crankshaft loads. It operates independently of the engine's lubricating-oil circuit and needs no maintenance or adjustment throughout its working life.
