New KTR flange coupling offers higher torque with no size increase

0

KTR will present its curved-tooth flange coupling BoWex FLE-PAC at Bauma 2019 in Munich, Germany, which helps to transmit power reliably, enabling the machine to perform operations as requested with higher torque than ever before.

With hydrostatic drives in construction and agricultural machines, IC engines and hydraulic pumps are directly coupled. Both units are connected by a flange coupling, which has to meet a number of requirements – reliable power transfer being its primary one.

BoWex FLE-PAC is a torsionally rigid curved-tooth flange coupling. Its hub is made of steel and the flange toothing of carbon fiber reinforced nylon. This material combination optimizes coefficients of friction in the tooth combination and provides the coupling with high dimensional stability even in temperatures up to 130°C – which allows for long periods of maintenance-free operation.

“Years of experience with applications at customer sites and extensive test series in the KTR test field in Rheine enabled us to determine potentials with this product, allowing for an increase of torque by up to 25%,” said Andreas Hücker, product manager for flange couplings in KTR.

“The low wear of contacts and the excellent dimensional accuracy of the coupling were decisive for the torque increase. The increased coupling torques definitely result in a bigger performance range with drives up to 800kW. Therefore, customers will be in a position to use smaller coupling sizes in their machines in the future.”

KTR will be exhibiting at Bauma, Munich, in Hall A4, Stand 145.
