A torsional vibration damper having limit stops to limit the compression of the springs and to avoid overstraining of the springs. Spring retainers which seat on the driving and driven members have protrusions and recesses to minimize relative rubbing motion and wear and provide improved alignment of the spring seats in the assembly with the springs ...

ABSTRACT A vibration damper assembly for use in a torsional coupling between a driving member and a driven member wherein the damper assembly provides for a very low rate, high amplitude deflection. The vibration damper includes a hub to be received on a driven shaft, two or more groups of springs having multiple springs of the came or various ...

Abstract In this paper the authors present a theory of the action of friction dampers on systems in torsional resonance, with special application to gas- and Diesel-engine installations. Model tests carried out to check this theory are described. The effect of introducing springs in the Lanchester damper is also discussed.

The construction of an internal-combustion engine is such as to make it susceptible to resonant torsional oscillation of the crankshaft. When an engine is operated near a critical speed, that is, a speed at which the pulsations produced by each cylinder excite the natural frequency of the crankshaft, excessive torsional amplitudes are developed which
