Abstract
A viscous damper has an inertial mass in the form of a tubular member that is applicable for dissipating (removing) destructive torsional vibration in power transmitting shaft assemblies. A viscous fluid contained between moving surfaces is sheared, thereby producing frictional heat which is then allowed to transfer across the moving surfaces to the ambient surroundings. Surfaces of the inertial mass and housing are arranged with respect to each other to provide high shear rate and energy dissipation (damping) is obtained within a small volume.
