Abstract
A torsional vibration damper of the type having an inertia ring coupled to a hub by an elastomer member. The inertia ring is formed of two axially spaced ring parts. Each ring part carries an annular groove. A radially extending disc locking element (in the form of a flat washer) carries an axially extending key, the ends of the key being deformed towards a radially extending position by pushing the two ring parts together, the deformed key ends thus holding the two ring parts in assembly. The disc locking element also is compressed and thus exerts an axial force urging the two ring parts apart. In an embodiment, the disc locking element carries a second axially extending key, radially spaced from the first key and is similarly deformed into a second annular groove. In still another embodiment, one inertia ring part carries an integral, axially extending locking key. This key is received by a complementary annular groove in the other ring part, the disc locking element being optionally omitted. A similar deformation and locking action occurs upon pushing the two ring parts together, to thereby assemble the damper.
