Our viscous torsional damper is a design that consists of a
free rotation inertia ring surrounded by a viscous silicone
fluid enclosed in a laser welded, sealed housing.
When crankshaft torsional vibrations occur, the outer
housing of the damper reacts with the crankshaft, twisting
as it rotates, while the inertia ring
attempts to rotate at a constant
speed. This relative motion
between the inertia ring and
housing causes the inertia
ring to shear the silicone
fluid, which reduces the
destructive torsional vibrations
of the crankshaft. When left
unchecked, these vibrations may
lead to a cracked or broken crankshaft,
valve train problems and premature bearing wear.
