ABSTRACT:
An improved viscous dampening arrangement for a taut-band suspension system in an electrical indicating instrument includes a hub associated with the stator and a turret associated with the rotor. The hub and turret each have central openings for receiving the taut-band. The hub and turret are arranged, in use, in a spaced-apart facing relationship with the facing portions of hub and turret being tapered in a controlled fashion. A viscous dampening fluid is provided between the hub and turret and an anti-wetting agent is applied to the surfaces of the hub and turret where the dampening fluid is not desired. The geometry of the tapers is chosen so as to minimize the effects of longitudinal and radial shocks and vibrations on the electrical indicating instrument.
