A lightweight, maintenance-free, composite coupling

GEISLINGER GESILCO® COMPOSHAFT

The Gesilco® Composhaft misalignment coupling consists of two double membranes and an intermediate shaft made of advanced composite materials. The membranes are corrugated with decreasing wall thickness as the diameter increases. The superior advantages of the corrugated membrane design, in comparison to a flat membrane, are a higher deflection capacity and lower, almost linear reaction forces.

The membranes and the intermediate shaft are bolted together at the flanges with fitted bolts. By using variable thickness spacers, installation tolerances and the centering recess can be compensated. Pre-stressed screws are used to connect the membranes to the driving and driven components. The lightweight Geislinger Gesilco® Composhaft can transmit the same torque and the same misalignments with a smaller outer diameter compared to the Gesilco® Butterfly and Geislinger steel spring coupling.

Composite membranes are corrugated with decreasing wall thickness as the diameter increases. The superior advantages of the corrugated membrane design, in comparison to a flat membrane, are higher deflection capacity and lower, almost linear reaction forces.

The membranes can be tailored to any required geometric and structural parameter. Filament wound, fiber reinforced tubes are used for the intermediate shafts. Glass fiber reinforced epoxy resins are non-magnetic, non-conductive and electrically insulating materials.

The Geislinger Gesilco® Composhaft can be adapted to general installation parameters. Due to the Gesilco® coupling’s design flexibility, complicated installation configurations can be realized as well.

The Geislinger Gesilco® product range is based on more than 25 years’ experience in developing fiber composite couplings and shafts. All Gesilco® products are manufactured in our Austrian Geislinger locations.
