Function
The torque is transmitted to the hub at the drive end via the shaft-
hub connection, which is mostly designed as a keyway connec-
tion, and is transmitted to the hub on the output side via the cam
ring. This hub then further transmits the torque to the driven ma-
chine or a gear unit placed in between. The special cam design
helps to keep the compression-loaded cam ring elements in
their defined position under all operating conditions and to keep
them evenly loaded. This results in a long lifetime of the flexible
elements. A long lifetime is also guaranteed by the hub parts
which ensure maximum operational reliability even under harsh
operating conditions.

Design
The N-BIPEX coupling of type BWN comprises two identical hub
parts connected by a cam ring of elastomer material.
The hubs are connected to the respective shafts via finished
bores with parallel keyway connection.
N-BIPEX couplings are positive-locking and torsionally flexible
thanks to the thermoplastic polyurethane cam ring.
