New test bench at KTR

10 June, 2016

Testing sample of the initial testing series is a torque limiter intended to be used on an 8 MW offshore wind energy plant. The new test bench includes 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, while the twisting angle is calculated on the drive side through a pulse encoder or a position sensor installed directly on the testing sample.

The data acquired allows users to calculate 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 can be tested and set.

With the introduction of the new test bench KTR’s testing capacities in Rheine have been increased five-fold. “The availability of this kind of test bench is particularly important in an age where the performance level of drive components for machinery and plant engineering is continuously increasing,” commented Reinhard Wibbeling, head of design/research & development at KTR.

Hydraulic, servo-hydraulic or electrical operation

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.
