KTR the family has the torsionally flexible jaw couplings "Rotex" a variant of maintenance-free use in hazardous areas expanded: The fail-safe "Rotex Non Sparking" can even be operated safely in the event of wear of the damping element and reliably avoid any sparks. The cam geometry is made of conductive and high-strength plastic, and is to the hub body, which continue to be made of steel or other metal materials such as aluminum, injected.
The newly developed plastic prevents any static charge and is designed so resistant that even in case of total wear of the elastomer, the torque is still transmitted without any risk of sparking. Maintenance can thus easily be moved in a non-critical time window.
The shock-proof and maintenance-free Rotex Non Sparking is judged by ex-Approved according to EC Directive 94 / 9 / EC. The shaft coupling axial plug-in compact relying. It provides good dynamic characteristics, excellent vibration damping and low mass moments. Due to the precision machining the running properties of the coupling are positively influenced and increases their life expectancy considerably. The dog clutch ensures a torsion-transmission and absorbs shocks produced by the uneven operation of equipment. The program also includes double cardanic design for large shaft misalignments with low restoring forces and good dynamic properties.
The spraying of the cam geometry offers a high product variance for ATEX applications, such as recessed hub for a very short design. Also customer and application specific shaft-hub connections are realized here in many forms.
