Couplings speed setups in engine testing
Diesel engine test benches use plug-in BoWex flange couplings from KTR in order to couple the engine to the test bench.
Manufacturers of diesel engines for construction machinery check the engines in detailed cold and warm tests before they leave the plant They increasingly use automated test benches that the engine automatically docks to

Rotex is KTR's most famous coupling series and is available in numerous variations including combinations with overload systems.
Shrouded coupling promises leak-free links
A permanent-magnet synchronous coupling provides semihermetic contactless torque transmission.
In older test benches, the prop shaft had to be screwed to the engine in order to measure its performance.
This is not necessarily the case anymore with the new test benches because numerous manufacturers use plug-in BoWex flange couplings from KTR in order to couple the engine to the test bench.
KTR has a range of flange couplings that are slightly unusual.
At the flywheel end of the diesel engine there is a highly flexible BoWex Elastic coupling with an integral spacer.
This special BoWex Elastic coupling engages into the BoWex FLE-PA that is connected to the test stand brake.
This self-centring, double-cardanic coupling system can be connected with a simple axial movement.
Thus, the manufacturer of the test bench can completely automate the connection process.
The combination of BoWex Elastic and BoWex FLE-PA compensates for radial, axial and angular displacements occurring during assembly of the coupling.
The BoWex FLE-PA couplings for this application have special teeth, enabling optimal connection of the engine and test stand coupling half.
Many applications have produced extraordinarily long lifetime of the coupling system.
When selecting flange couplings for engine test benches, KTR co-operates with several leading manufacturers of test benches.
The performance range of the engines to be tested goes up to 750kW.
The majority of applications for the torsionally flexible BoWex Elastic and for the torsionally stiff BoWex FLE-PA, which both use the low-wear curved-tooth gear principle avoiding edge pressures at the contact positions of the couplings, is still in the mobile machines: Here the couplings reduce torsional vibrations and thus contribute to a longer lifetime of the total drive train.
