Services N-BIPEX Claw Coupling
- Damping shaft coupling that can be used universally to compensate for shaft misalignments
- Nominal torque range from TKN = 12 Nm up to 4,650 Nm with 10 sizes
- Temperature range: from – 50 °C to +100 °C
The better choice of coupling for the process industry
The coupling portfolios normally found on the market consist of comparable couplings with a maximum permissible torque corresponding to twice the coupling’s nominal torque. To be on the safe side – for example during the run-up phase of an asynchronous motor with typical starting torques and tilting moments – it is often necessary to fall back on the next-largest coupling size. If high rotational speeds or relatively large bores need to be taken into account, the market often offers costly steel solutions. The N-BIPEX® copes with just these situations and offers not only higher maximum torques but also an extended range of bores.
With its cast hubs, the N-BIPEX allows greater freedom when designing the cam geometry, thereby laying the foundation for the innovative curved design. Unlike the milled cams typically available on the market, this design results in uniform loading of the elastomer compression bodies under all conditions and, in particular, prevents inward deformation of the cam ring due to load peaks that can cause greater wear. Hubs made of high-quality nodular cast iron allow the N-BIPEX to cope with high rotational speeds and critical bores. All in all, the N-BIPEX provides reserves that are considerably greater than those normally available on the market, thus achieving a significant reduction in wear.
