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

The lightweight COMPOSHAFT® compensates radial, axial, and angular misalignments. Drivetrain systems benefit from low, almost linear reaction forces as well as from the highest torque transmission with the best dynamic behavior. Further advantages are electrical insulation and non-magnetic properties. Even under extreme conditions, the highest shock resistance of this coupling is a great benefit.

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 membranes can be tailored to any required geometric and structural parameter. With this modular design, the COMPOSHAFT® covers a wide range of different applications.

The Geislinger COMPOSHAFT® can be adapted to general installation parameters. The lightweight misalignment coupling can be combined with a Geislinger torsional elastic coupling and is suitable for a wide range of applications. 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 of experience in developing fiber composite couplings and shafts. All GESILCO® products are manufactured at our Austrian Geislinger locations.
