POLY-NORM
Manufacturer: KTRThe POLY-NORM is a torsionally flexible, fail-safe jaw coupling by KTR Systems with an elastomer intermediate ring for damping and misalignment compensation.
The POLY-NORM transmits torque via interlocking jaws (cams) between which an elastic elastomer intermediate ring carries the torque under compression. This intermediate ring damps torque shocks and torsional vibration and compensates axial, radial and angular shaft misalignment. Should the elastomer ever fail, torque transmission is maintained by the positive engagement of the jaws: the coupling is fail-safe.
As a torsionally flexible, fail-safe jaw coupling, the POLY-NORM combines good damping with a compact, robust design and easy assembly. The elastomer intermediate ring is a wear part and can be replaced easily. The fail-safe behaviour increases operational reliability in demanding drives.
The POLY-NORM is available in different sizes and elastomer hardnesses and can therefore be matched to different torque and damping requirements.
