POLY-NORM®AZR-COUPLING FOR DISMOUNTING

Product characteristics
  • Flange coupling for torque transmission and damping of torsional vibrations
  • Axial plug-in - easy assembly - maintenance free
  • Intermediate tube in standard length - to be mounted and dismounted radially
  • Operative range from - 30 °C to + 80 °C peak temperature of up to + 120ºC
  • Compensation for axial, radial and angular shaft misalignments
  • Use particularly in pump industry and for compressors
Coupling description The POLY-NORM® coupling is a torsionally flexible, shear type shaft coupling. It has an axial plug-in design with a unique short over all length. The POLY-NORM® can be used in nearly all types of machinery and is ideal for the pump industry. The POLY-NORM® coupling compensates for shaft misalignment of all kinds and safely transmits the torque.
Function
z_95-ar-explo
The coupling consists of two hubs, with fingers separated by elastomeric elements. The hubs are assembled blindly plugging the hub fingers into each other axially and the elastomer ring is trapped in a groove between both coupling hubs. The compact POLY-NORM® coupling transmits torque with the elastomer in compression. Shaft misalignments, vibrations and shock loads are effectively absorbed by the POLYNORM ®. The coupling is maintenance-free and used in general machinery, the pump industry and in compressors. Torques of up to 26,800 Nm are stocked in 17 different sizes and 7 designs. In addition to the standard coupling models, flange drop out center and spacer options are available in many variations. Explosion protection use

POLY-NORM® couplings are suitable for the use in drives in hazardous areas. The couplings are certified according to EC Standard 94/9/EC (ATEX 95) and belong to category 2G/2D, are confirmed and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22. Please read our information in the respective Type Examination Certificate and the operating and mounting instructions under www.ktr.com. Variaition of options

The coupling can be adapted to many applications due to the many options that are possible with the building block arrangement. The POLY-NORM® components of a given model can be mixed and matched with each other to obtain different shaft distances using the same basic component. On request, we can provide customized variations of the POLY-NORM® to fit your needs – for example, our POLY-NORM® overload coupling with RUFLEX® torque limiter. Just ask us!
