ABSTRACT:
A damper and method for tuning a damper utilizing a surface contact reducing resilient member is disclosed. A damper for dampening torsional and bending vibrations in a rotating shaft includes a hub member, an inertia member spaced radially outwardly from the hub member, and a resilient member positioned under compression between the hub member and the inertia member. The resilient member has at least one protrusion extending axially thereon to reduce the amount of surface contact between the resilient member and the hub member or the inertia member. A method for tuning dampers is also disclosed wherein reducing the amount of surface contact between the resilient member and the hub member and inertia member allows the damper to achieve lower part frequency based primarily on the geometry of the resilient member.
