BoWex-ELASTIC® HEW1(HEW2) highly flexible flange couplings

The coupling type BoWex-ELASTIC HEW1/HEW2 is a highly flexible shaft coupling.

This type combines a standard BoWex-HE elastomer with a flange hub and a curved-tooth hub.

The HEW1/HEW2 is applicable up to a maximum operating temperature of 100 °C.
The combination with the coupling hubs of the BoWex standard range enables compensation of misalignment.

The flange coupling is assessed and approved for potentially explosive atmospheres acc. to EC directive 2014/34/EU. Differentiating between the respective type 1 and 2 results in an either short (2) or long (1) version of the coupling.

  • Highly flexible shaft coupling
  • For mounting to piston engines, electric motors, etc.
  • Easy assembly due to axial plug-in
  • Particularly suitable for blind assembly
  • Taper and inch bores
  • Wide stock range with finish bores H7 and keyway to DIN
  • Spline hubs acc. to DIN and SAE standard
  • Lengthened hubs available from stock
  • Special types of hubs available
  • Complying with ATEX (acc. to EU directive 2014/34/EU)
  • UKEX compliant (according to UKEX Directive SI 2016:1107)
  • Max. torque 30,000 Nm
  • Max. circumferential speed vmax=48 m/s
  • Max. bore diameter 200 mm

For drives subject to severe torsional vibrations for flexible torque transmission in the combination of a diesel engine with splitterbox, generator, compressor, feed pump or high-pressure pump, etc.: The BoWex-ELASTIC flange coupling consists of a highly flexible, circular rubber element made of natural rubber stressed for torque-to-bore ratio. The internal axial plug-in hub component with the external spline corresponds to the BoWex basic type. The BoWex-ELASTIC is available in various kinds of elastomer hardness with mounting flanges on the engine side acc. to SAE J620 and with special dimensions for a power up to 5,000 kW.

  • Various kinds of Shore hardness
  • Torsional vibration analyis
  • Supercritical selection
  • Temperature resistance (enabling higher temperatures via EPDM)
