A hub construction for a torsional vibration damper. The hub is formed of aluminum to obtain the known damper performance advantages of a lower moment of inertia. The hub is coated with a Teflon anodized layer to (1) protect it from oxidation, to (2) prevent the formation of aluminum oxide particles at the elastomer-hub interface. The coating is of a surface roughness of 60-70 micro inches, being a roughness in excess of that recommended by seal manufacturers. Unexpectedly, the coating does not injure a seal used with the damper, thus yielding a third advantage. |
