KWD ELKU-N H Elastic Couplings

ELKU-N H series kits are complete sets of parts for assembling the KWD ELKU-N H shaft coupling.

KWD ELKU-N H are torsionally flexible, puncture-proof shaft couplings. They transmit torque through pressure-stressed elastic "H" shaped buffers to absorb shock and torsional vibrations. These buffers are not connected to each other but are individually mounted in the hub. The set of buffers then corresponds to a discontinuous ring-shaped element. This element is oil resistant and electrically conductive.

Due to pump design, one of the hubs is composed of three parts – a flange hub, an outer claw ring and a spacer, which is bolted to the hub and claw ring. When disassembling, there is no need to move the individual machine parts and the necessary space is created (e.g. for removing the pump rotor). ELKU-N coupling hubs are made of grey cast iron, either unbored or with a pilot bore. They are therefore supplied as semi-finished products and the bore must be adjusted before mounting the coupling on the shafts.

ELKU-N couplings can be used for both directions of rotation and each mounting position. They are compatible with Flender N-EUPEX couplings.

Couplings Fields of Use

ELKU-N elastic couplings are designed for the highest requirements in a wide range of industries, especially for compressors, pumps, conveyors and many other machines.

They are available in two-part or three-part versions and in many other variants with brake discs, brake drums or with spacers. The three-part design allows the replacement of elastic elements without the need to disassemble the machine.

Couplings Characteristics

  • Compensates for angular, parallel and axial shaft misalignments of the connected machines
  • Elastic elements operate in temperature ranges of −30 °C to +100 °C
  • Replacement of elastic elements without axial movement of the coupled machines
  • Nominal torque TKN form 25 to 100,000 Nm.
  • Dimensions interchangeable with N-EUPEX couplings and other similar types
