VIBRATION DAMPER

The twisting of the crankshaft due to the regular

power impacts along its length

is called twisting

(torsional) vibration. The vibration damper is installed on

the front end of the crankshaft. It is used for reduction of

torsional vibrations and stops the vibration from building

up to amounts that cause damage.

The damper is made of a flywheel ring (1) connected

to an inner hub (3) by a rubber ring (2). The rubber makes

a flexible coupling between the flywheel ring and the inner

hub.
