Geislinger Coupling

Design

The classic Geislinger Coupling is a torsionally elastic, high damping coupling which uses radially arranged steel spring packs. The coupling is essentially made of the same material as that used for diesel engines and the associated driven components. The major components for a standard design are shown in Fig. 1.

Stiffness

The steel spring packs represent the primary component of a Geislinger Coupling. The steel spring packs can be produced to any degree of stiffness within a wide range. The spring packs can be made as ‘multiple blade’ design or ‘conical blade’ design. The ‘multiple blade’ design consists of more than two blades, the ‘conical design’ has only two conical shaped blades (See Fig.2). It should be noted that spring stiffness has no effect on the required damping of a given system. The stiffness series, listed in this catalog, shows a standard progression for the ‘multiple blade’ design based on the requirements of most applications. Technical data for ‘conical blade’ designs are available on request. If torsional requirements dictate an unlisted spring stiffness, springs can be fabricated to the required stiffness without additional lead-time or cost.
