TORSIONAL VIBRATION - When does it occur? Torsional vibration problems occur with internal combustion engine driven systems such as Pumps, Compressors and Generators as well as in Vehicle and Marine propulsion systems. Torsional vibration occurs when the natural frequency of the drive train is coincidental with the torsional vibration frequency of the prime mover (normally the engine) driving at normal operating speeds. |

When this occurs the drive train can experience transient torques well in excess of its design specification and this can lead to excessive noise and vibration problems and in the worst case complete drive failure.
KUSEL COUPLINGS - How to cure the problem of torsional vibration The introduction of a Kusel Coupling into the drive train will alter the natural frequency outside the normal operating speeds (normally below). By combining the torsional flexibility of the rubber elements with varying degrees of damping a Kusel Coupling can be selected to suit almost any application. The Kusel Coupling comes with a multitude of different mounting options to suit any mounting configuration. The Couplings can be supplied complete with a Cardan Shaft to offer a powerful combination of torsional and misalignment flexibility, in one Coupling/Shaft package. |
