Abstract
A rubber or rubber/viscous torsional damper assembly of the type having an annular inertia mass mounted for relative torsional damping movement on an annular body portion of a rotor disk has elastic rings fixedly secured to the rotor body portion and pressing against a substantial radial width of axially inwardly facing surface area within a chamber in the inertia mass under preload compression. Annular ribs on the rings fits in annular grooves at the radially inner sides of the surface areas and substantially restrain the elastic rings against radially inward extrusion flow displacement, so that the preload compression is maintained radially outwardly relative to the ribs. Additional grooves adjacent to the radially outer sides of the surface areas receive complementary ribs on the rubber rings for controlling against radially outward rubber displacement in the viscous/rubber damper assemblies.
