<p>A Torsional Vibration Damper 10 includes a hub 12, a ring 14, and a rubber member 16 that is compression fitted between the outer surface 26 of the hub 12 and the inner surface 32 of the ring 14. The cross-sectional profile of the outer surface of the hub and the inner surface of the ring after the assembly of the TVD consists of two concave or convex arcs with their radii such that the cross-sectional profile's gap increases from the center to the sides. This variation of the cross-sectional profile's gap reduces the principal-strain buildup in the rubber 16, thereby improving the life of the Torsional Vibration Damper 10. This design also facilitates proper assembly as the components are self aligning.</p> |
