KTR has launched a new test bench for large couplings covering a performance range of up to 500,000 Nm at its headquarters in Rheine, Germany. The test bench allows the calculation of mechanical coupling parameters and performce service life testing. The testing sample of the initial series is a torque limiter intended to be used in an 8 MW offshore wind energy plant.
The new test bench is provided with an electrical variable-speed drive generating a maximum testing torque of 500,000 Nm via several gears. The torque is measured on the gear output side through a calibrated measuring shaft via DMS technology. Meanwhile, 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 allows engineers to calculate 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 here.
With the new test bench, KTR’s testing capacities in Rheine have been increased five times. “The availability of such a test bench is particularly important in an age when the performance of drive components for machinery and plant engineering is continuously increasing,” said Reinhard Wibbeling, Head of Designing/Research & Development in KTR. This allows KTR to further expand its position as a manufacturer of mechanical couplings and overload systems.
KTR’s test bench for mechanical couplings and overload systems at the headquarters in Rheine 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 to 500,000 Nm and allow for practical testing conditions with dynamic or static loads. The testing capacity includes determination of coupling parameters, adjustment of overload systems and endurance testing regarding component strength and service life.
