<p>A torsional vibrator damper of the type having a hub and an inertia ring, the hub and inertia ring coupled to each other by an elastomer member. The hub is adapted to be coupled to the crankshaft of an engine. The inertia ring is formed of two axially spaced ring parts with each ring part having at least one annular groove. A ring locking element is provided in the form of a radially extending disc carrying at least one generally axially extending locking key, and the axially outermost ends of the locking key are received in, respectively, the ring part annular grooves. The axially outermost ends of the locking key are each deformed to each define a tang which extends at least partially in a radial direction. The radially extending disc is under axial compression and thus exerts an axially extending force against the two ring parts to urge them apart. The tangs of the locking key contact portions of the annular grooves to resist the disc axially directed force. The annular grooves are trapezoidal in longitudinal cross-section. The longest parallel side of each trapezoid is farthest from the junction of the two ring parts.</p> |
