Siemens releases Flender N-Bipex coupling

April 21, 2015 - Siemens releases Flender N-Bipex coupling, available in ten sizes made of high-quality nodular cast iron.

Suitable for applications in the chemical, environmental engineering and steel industries, the elastic claw coupling has an optimized cam geometry and elastomers for a major improvement to the service life of the N-Bipex.

Depending on the size, torque has been increased by between ten and 20 percent over previous solutions. The elastomers are available in three different shore hardnesses, and allow the couplings to be used across a temperature range of -50° C to +100 °C without compromising nominal torque. Flender N-Bipex couplings are used predominantly in connection with hydraulic systems and geared motors, meaning that they are found across the whole of the machine building sector, with applications throughout the chemical, environmental engineering and steel industries.

Elastomers and use of the nodular cast iron casting method allow the Flender N-Bipex claw coupling to achieve improved and, most importantly, temperature-independent performance alongside a high degree of freedom for shaping the cams.

The casting method used increases the degree of freedom for shaping the cams. This added scope enables the contour to be designed to ensure optimum engagement of the load flank surfaces. The decisive factor here is that the adjacent cam ring made of high-grade polyurethane has the facility for sufficient load-dependent deformation, while remaining in its designated position under all conditions. This results in a marked reduction in wear coupled with increased performance. The degree of resilience to forced rupture and the maximum admissible speeds achievable with nodular cast iron couplings are far superior to those of grey cast iron couplings, and are comparable to their steel counterparts.

The elastomers used for the Flender N-Bipex are designed for high performance. They are capable of withstanding dynamic loads across a very wide temperature range without restriction. The material used offers excellent compressive strength, wear resistance, dimensional stability and ductility.
