Vibration damper
First Claim
1. A damper for shafts, comprising:
- an elastomeric ring;
an inertia ring mounted on the elastomeric ring such that the elastomeric ring secures the inertia ring in a position; and
a first housing portion engaging a second housing portion wherein the first and second housing portions form a u-channel wherein the u-channel abuts an inner portion of the elastomeric ring to maintain the inertia ring in the position such that the inertia ring floats on the elastomeric ring permitting motion in three dimensions responsive to mechanical disturbances without the inertia ring contacting the first and second housing portions.

Abstract
A damper for shafts includes an elastomeric ring having a plurality of holes therethrough and an inertia ring having two portions such that the portions encapsulate the elastomeric ring and secure the elastomeric ring in a position. The inertia ring includes openings corresponding to the plurality of holes in the elastomeric ring. A first housing portion configured to receive first fasteners through a first set of openings in the elastomeric ring and the inertia ring to secure the first housing portion to a second housing portion. The first and second housing portions form a surface to receive an inner portion of the elastomeric ring such that the inertia ring floats on the elastomeric ring without the inertia ring contacting the first and second housing portions.

10. A damper for shafts, comprising:
-
an elastomeric ring having a plurality of holes therethrough, each hole having a stand-off disposed therein configured to receive a fastener therethrough; an inertia ring encapsulating the elastomeric ring and securing the elastomeric ring in a position, the inertia ring including plate portions and having openings corresponding to the stand-offs; and a first housing portion configured to receive first fasteners through the elastomeric ring through a first set of stand-offs and through openings in the inertia ring to connect the first housing portion to a second housing portion wherein the first and second housing portions form a u-channel wherein the u-channel abuts an inner portion of the elastomeric ring to bias the inertia in the position such that the inertia ring floats on the elastomeric ring permitting motion in three dimensions responsive to mechanical disturbances without the inertia ring contacting the first and second housing portions. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A crankshaft damper, comprising:
-
a polyurethane ring having a plurality of holes therethrough, each hole having a stand-off disposed therein configured to receive a fastener therethrough; an inertia ring having two portions such that the portions encapsulate the elastomeric ring and secure the elastomeric ring in a position, the inertia ring including plate portions and having openings corresponding to the stand-offs; a first pulley housing portion configured to receive first fasteners through a first set of stand-offs in the polyurethane ring, the first fasteners passing through the polyurethane ring and openings in the inertia ring, the first pulley housing portion having an outside diameter configured to receive a belt; and a second pulley housing portion configured to receive the first fasteners and connect the first and second pulley housings, the second pulley housing portion having an outside diameter configured to receive a belt, wherein the first and second pulley housing portions form a channel to receive an inner portion of the elastomeric ring, the channel abutting the inner portion against a bottom and sides of the channel, the first pulley housing portion and the second pulley housing portion further forming a hole which receives an interchangeable hub for receiving a shaft, wherein the inertia ring floats on the elastomeric ring without the inertia ring contacting the first and second housing portions such that the polyurethane ring is configured to damp any of longitudinal deflections, torsional deflections, orbital deflections and radial deflections of the shaft. - View Dependent Claims (19, 20)
