The COMPOSHAFT® misalignment coupling comprises two double membranes and an intermediate shaft 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 ﬂat membrane, are a higher deflection capacity and lower, almost linear reaction forces.
The lightweight COMPOSHAFT® compensates for radial, axial, and angular misalignments. Drivetrain systems benefit from low, almost linear reaction forces and 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. Installation tolerances and the centering recess can be compensated using variable thickness spacers. 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.
