TORSIONAL VIBRATION DAMPERS
First Claim
1. A torsional vibration damper comprising:
- a hub having a shaft-receiving member defining an axis of rotation and a plate extending radially outward about the shaft-receiving member;
a first portion of an inertia member defining a back face and a bore therethrough and having an annular flange concentric about the axis of rotation, wherein the shaft-receiving member of the hub is positioned in the bore with the plate of the hub spaced a distance from an interior surface of the annular flange;
a first elastomeric member and a second elastomeric member positioned against opposite sides of the plate;
a second portion of the inertia member fastened to the first portion of the inertia member by one or more fasteners thereby placing the first elastomeric member and the second elastomeric member in compression.

Abstract
Torsional vibration dampers are disclosed that have a hub having a plate extending radially outward about a shaft-receiving member, a first portion of an inertia member defining a back face and a bore therethrough and having an annular flange concentric about the axis of rotation, a first elastomeric member and a second elastomeric member positioned against opposite sides of the plate, and a second portion of the inertia member fastened to the first portion of the inertia member by one or more fasteners, thereby placing the first and second elastomeric members in compression. The shaft-receiving member of the hub is positioned in the bore with the plate of the hub spaced a distance from an interior surface of the annular flange, and the plate of the hub and the interior surfaces of each of the first and second portions of the inertia member facing the plate define dual common vertices.
