POLY-NORM® ADR torsionally flexible, fail-safe shaft coupling

Shaft coupling with elastomer ring replaceable when installed

The torsionally flexible, fail-safe shaft coupling POLY-NORM ADR is a compact three-part shaft coupling for torsional vibration-damping power transmission.

The three-part POLY-NORM ADR shaft coupling allows for eliminating positive-locking fit without shifting the driving or driven side axially. The elastomer ring (spider) can be replaced when installed.

  • Three-part shaft coupling for torsional vibration-damping power transmission
  • Axial plug-in, easy assembly, easy to service
  • Maintenance-free
  • Compact, short shaft distance dimension
  • Applications: general engineering
  • Elastomer spider can be replaced when installed
  • Axial, radial, angular compensation
  • Complying with ATEX (acc. to EU directive 2014/34/EU)
  • UKEX compliant (according to UKEX Directive SI 2016:1107)

POLY-NORM® shaft couplings are characterized by a compact design. The torque is transmitted via elastomers between the cams also serving to offset displacements and dampen shocks and torsional vibrations.

Applications of our torsionally flexible, fail-safe shaft couplings:
POLY-NORM shaft couplings are used in almost all fields of mechanical engineering, here mainly in the pump industry (pump coupling).

Overview of our fail-safe shaft couplings:

Operation of fail-safe shaft coupling:
The POLY-NORM shaft coupling consists of two hubs half the cams of which are each inserted in the tailor-made free spaces of the other hub.

This compact design of the shaft coupling allows to connect the shafts with a particularly short shaft distance dimension. The elastomer positioned between the cams transmits the torques while compensating for any kind of displacement.

Variation of components of fail-safe shaft coupling:
High adaptability with low variance through an optimally differentiated construction kit system: The elements within one size of POLY-NORM® shaft coupling can easily be combined with each other. This allows to realize various shaft distances with the same basic component.
