Vibration Damper in Crankshaft


The Vibration Damper in crankshafts is a components that serves to balance the torsional and resonance vibrations in the crankshafts.  The torque produced by an internal combusion engine is not a smooth one like that produced by a turbine.  The IC engine generate power in strokes.  When each cylinder fires, a stroke of power is generated.  This results in a pulsating torque developed in the crankshaft. 

The Vibration Damper contains an inertia. rings which rotates in a layer of silicone fluid.  The vibrations are dissipated in the fluid.  Overtime, the fluid can become thick and hard.  This reduces the damping property

This torque needs to be smoothened.  This is done by the flywheel which stores the power and delivers it uniformly.  However, this can produce oscillations.  These oscillations can damage the crankshaft if they reach resonance or if they become large. 

The vibration damper prevents this by absorbing the vibrations.  The vibrations are not transmitted to other components such as the couplings or the drive train or any other load. 

Vibrations dampers can deteriorate over age.  As this happens, increased vibrations and noise can be observed.  Hence, the should be examined periodically.
