Shaft Coupling Description

ELKU-N A2500 (Nx A520, Bore: 155-190 mm, Cast Iron) is a set of parts for assembling the KWD ELKU-N shaft coupling.

KWD ELKU-N is torsionally flexible, puncture-proof shaft coupling. It transmits 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

This ELKU-N coupling is of series A. One of the hubs is therefore composed of two parts – a flange hub and an outer claw ring, which is bolted to the hub. When replacing the worn flexible element, or disassembling and assembling, it is not necessary to move the individual machine parts, but it is sufficient to disassemble the two-piece hub.

ELKU-N coupling hubs are made of gray cast iron. They are supplied as semi-finished products and the bore must be adjusted before mounting the coupling on the shafts.

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

Shaft Coupling Construction

  4. Pan-head screws with washers
  5. "H" shaped elastic buffers inside

Shaft Coupling 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.

Shaft Coupling 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
