<strong>FLENDER</strong> <strong>Standard</strong> <strong>Couplings</strong><br />
Torsionally Rigid All-Steel <strong>Couplings</strong> — ARPEX ARF-6 Series<br />
General information<br />
■ Overview<br />
Coupling can be designed for potentially explosive<br />
environments in accordance with 94/9/EC.<br />
1275 Newton, local 15<br />

■ Benefits<br />
ARPEX couplings of the ARF-6 series are extremely short and so<br />
suitable for drives with short shaft distances. They also serve as<br />
self-aligning couplings for axial, angular and radial misalignment.<br />
The hubs are available both as pure clamping hubs for<br />
smooth shafts and with parallel keyway for shafts with parallel<br />
■ Application<br />
ARPEX couplings of the ARF-6 series are designed for minimum<br />
fitting spaces without having to sacrifice the advantages of the<br />
two-joint coupling. It is thus possible to compensate for both axial<br />
and angular as well as radial misalignment. By using halfshell<br />
clamping hubs, the coupling can be radially freely dismounted.<br />
Power is transmitted via hexagon socket head cap<br />
screws and close-fitting bolts with nuts and ring plate packs in<br />
key. The variant with slit clamping hubs enables the delivery of<br />
fully preassembled couplings. This means that the entire coupling<br />
can be dismounted and fitted without moving the connected<br />
units.<br />
hexagonal design. Torques of between 120 and 6100 Nm can<br />
be transmitted at a permitted angular misalignment of 0.7°.<br />
Main areas of application for the ARF-6 series:<br />
•Film stretching machines<br />
•Machines in the cellulose industry<br />
• Machines in confined fitting situations<br />

■ Design<br />
The two plate packs form a unit with the adapter disk and are<br />
screwed together with close-fitting bolts and nuts at three points.<br />
The alternate connection of this intermediate unit with the<br />
flanges of the split coupling hubs is achieved by means of short<br />
hexagon socket head cap screws at further three points. The<br />
hubs are designed as axially slit clamping hubs with a half-shell.<br />
For larger bores these can be manufactured as jumbo hubs.<br />
Optionally, the hubs are also available without parallel keyway.<br />
