TORSIONALLY RIGID ALL-STEEL COUPLINGS ARPEX ARF-6 SERIES

DESCRIPTION: ARPEX couplings of the ARF-6 series are designed for minimum fitting spaces without having to sacrifice the advantages of the two-joint coupling. It is thus possible to compensate for both axial and angular as well as radial misalignment. By using half-shell clamping hubs, the coupling can be radially freely dismounted. Power is transmitted via hexagon socket head cap screws and close-fitting bolts with nuts and ring plate packs in hexagonal design. Torques of between 120 and 6100 Nm can be mtransmitted at a permitted angular misalignment of 0.7°.

SPECIFICATIONS

TORSIONALLY RIGID ALL-STEEL COUPLINGS ARPEX ARF-6 SERIES

- Nominal torque range from TKN= 120 Nm up to 6100 Nm with 10 sizes

- Diameter (mm): from 84mm to 267 mm

- Speed (rpm): from 12.500 to 3.900 rpm

- Two Variants of the ARF coupling:

+ GG Variant with 2 standard clamping hubs

+ GJ Variant with 1 jumbo clamping hub for large bore

Benefits of the ARF Couplings

- Arpex couplings of the ARF-6 series are extremely short and so suitable for drives with short shaft distance.

- They also serve as self-aligning couplings for axial, angular and radial misalignment.

- The hubs are available both as pure clamping hubs for smooth shafts and with parallel keyway for shafts with parallel key.

- The variant with slit clamping hubs enables the delivery of fully preassembled couplings.

- The entire coupling can be dismounted and fitted without moving the connected units.
