For use in special high-speed test stands torsionally rigid, flexible couplings are ideally suited. The thin metal bellows have in addition to the balancing, also vibration-damping properties. The high flexibility of the KSD couplings from Jakob with its 6-wave bellows and the easy mounting option of the coupling through the use of cone bushes as shaft-hub connection guarantee a safe transmission of all forces and torques, even with small shaft diameters and without additional feather key , The rotationally symmetric design ensures excellent, dynamic operating behavior, even at very high speeds. The high torsional rigidity and the very low restoring forces with shaft misalignment as well as the low moment of inertia characterize the coupling type. Torques from 10 to 4000 Nm are possible. Highest quality processing and the materials used make the KSD couplings a reliable and economical component.
It is used, in addition to the test stands as a highlighted example, also particularly often in servo and actuators.
