KTR has extended the portfolio of highly torsionally flexible flange couplings of the BoWex-ELASTIC HE line by two sizes. The new flange couplings are available in different Shore hardnesses and suitable for high-performance drives of up to 5,000 kW.
The BoWex-ELASTIC HE is a flange coupling with high torsional flexibility consisting of a circular elastomer. The rubber element is made of vulcanized natural rubber and stressed for torque-to-bore ratio. It reduces the torsional vibrations occurring in the drive train as well as the cumulative forces and, due to different elastomer hardnesses, the flange coupling can be adjusted to the respective application for a resonance-free operation. The plug-in coupling hub is designed according to the BoWex curved-tooth gear principle and compensates for axial, radial and angular shaft displacements.
KTR has now expanded the BoWex-ELASTIC HE line by the sizes 240 HE and 275 HE – making the coupling suitable for drives of up to 4,000 kW and 5,000 kW, transmitting torques of up to 32,000 Nm and 45,000 Nm. Possible application fields are gensets, pumps and compressors, as well as high-performance stationary and mobile drive systems.
