FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings — ARPEX ARW-4/-6 Series
General information
■ Overview
© Siemens AG 2011
Coupling can be designed for potentially explosive
environments in accordance with 94/9/EC.

■ Benefits
ARPEX couplings of the ARW-4/-6 series are outstanding for
their large angular misalignment capacity of 3°. They were specially
designed for drives where high misalignments which have
to be compensated for by the coupling are to be expected. The
intermediate spacer lengths are variable and are manufactured
to customer specifications.

■ Application
ARPEX couplings of the ARW-4/-6 series are used where large
misalignment capacities are required. In the paper-making machine
industry, the ARW coupling has already proved itself as a
maintenance-free alternative to the cardan shaft. Torques of between
92 and 80000 Nm can be transmitted at a permitted angular
misalignment of 3.0°. The intermediate spacer can be fitted
radially without moving the connected units.
Main areas of application for the ARW-4/-6 series:
•Paper-making machines
• Wind power systems
• Traction drives
■ Design
The design of an ARPEX NHN coupling of the ARW-4/-6 series is
shown in the following illustration. The plate packs are bolted alternately
between the flanges of the coupling hubs and the intermediate
spacer. Up to size 292-4 close-fitting bolts and from size
324-4 conical screw connections are used for fastening. Up to
size 647-4 plate packs in rectangular design, from size 695-6 in
hexagonal design are used. The intermediate spacers are variable
in length and are manufactured specifically to customer
specifications.
