Large coupling test bench

The new test bench is equipped with an electrical variable-speed drive generating a maximum testing torque of 500,000 Nm via several gears. Torque is measured on the gear output side through a calibrated measuring shaft via DMS technology, while the twisting angle is calculated on the drive side through a pulse encoder or a position sensor which is installed directly on the testing sample. The data acquired allows to calculation of the torsion spring stiffness.

Apart from recording mechanical coupling figures, testing of component strength and service life is performed on the new test bench. In addition positive-locking and frictionally engaged overload systems will be tested and set.

KTR’s test bench for mechanical couplings and overload systems currently comprises 24 rotating and non-rotating test benches operated hydraulically, servo-hydraulically or electrically. The test benches cover a test range from 0.2 Nm to 500,000 Nm and allow for practical testing conditions with dynamic or static load of the testing sample. The testing capacity includes determination of coupling parameters, adjustment of overload systems and endurance testing regarding component strength and service life.
