Use of torsionally rigid metal bellows couplings in Special high-speed test benchs

Special high-speed test benches are used to test bearings.

In these tests, the effects of different lubricants on the sliding properties of the bearings in the endurance test are checked. The structural design of such a test rig must meet different requirements. The drive is subject to special conditions. In addition to a lateral force-free storage, the coupling is a not to be underestimated component. Essential features in this case are the absolute torsional rigidity, the good damping properties and, of course, the precise and almost powerless compensation of all offset errors between the shaft ends.

For such applications, torsionally rigid flexible couplings are generally ideal. The thin metal bellows have in addition to the balancing, also vibration-damping properties. The high flexibility of Jakob's KSS couplings with its 2-wave bellows and straight adapter and the easy mounting option of the coupling through the use of cone bushings as a shaft-hub connection guarantee a safe transmission of all forces and torques, even with small shaft diameters and torques 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 25 to 2500 Nm are possible. Highest quality in processing and the materials used make the KSS couplings a reliable and economical component. It is used, in addition to the test stands as a highlighted example, also particularly often in servos and actuators.

The machining of large workpieces presents its own challenges. Depending on the nature of the workpiece, very high clamping forces must be applied. Clamped with face plates or claw boxes, the processing time can also be several days and shift changes. Conventional clamping has various disadvantages. Fluctuations in the clamping force arise due to the generation of pretensioning forces that are prone to losses. An inhomogeneous state of tension in the parting line and variable generation of clamping force by different users are also disadvantageous. Automatic loosening due to vibrations is also possible.

ZSF - Fully clamped
The hydromechanical spring-loaded cylinders of the ZSF series from JAKOB Antriebstechnik offer robust and reliable clamping elements. These spring-loaded systems can be used wherever displaceable or movable machine parts must be temporarily clamped or locked. Other applications can be found in jig construction and for workpiece or tool clamping.
In order to find the right clutch for a drive train some factors have to be taken into account. The required torque range, the offset and the ambient temperatures of the clutch are particularly important.
