Propeller Shaft Damper


Prop Shaft Dampers are used to reduce or eliminate overlying rotational vibration that is transferred from the internal combustion engine to the drive shaft. For the design of a prop shaft damper, this means that the first stage is to find an appropriate installation location on the drive shaft or to adapt the design to the existing installation situation. However, the drive shaft absorber should generally be located as close as possible to the origin of the vibration problem, in order to allow the use of a absorber which weighs as little as possible. Generally, a rotational vibration absorber always consists of a hub, an elastomeric element and an inertia ring. For cost reasons, it is recommended to use sheet metal parts for the hub and cast iron for the inertia rings.
