ArcusaFlex Flange Coupling - Chain & Drives

Brands > Reich Couplings > ArcusaFlex Flange Coupling

The Reich ARCUSAFLEX® flange coupling has a highly flexible torque transmission characteristic which is achieved by a disc-shaped rubber element that is subjected to a torsional load and enables both, the absorption of high torsional vibrations and the compensation of major misalignments.

For an optimum adaptation to the conditions of application three different kinds of vulcanisates are available:

For application temperatures up to 80°C a natural/synthetic caoutchouc mixture as a standard version
up to 100°C a more heat resistant mixture and
for higher application temperatures up to 130°C a silicone mixture.

Benefits

Advantages of the highly flexible ARCUSAFLEX® coupling:

Very high torsional flexibility with a linear torsional deflection characteristic
Backlash-free torque transmission
Ease of assembly thanks to the plug-In type design 11 with ample axial float
High torsional vibration and shock load absorbing capability
Compensation of major misalignments
Torque limitation protecting the drive against overload

Arcusaflex element Shore hardness Sh A, Resonance factor VR and relative damping Ψ.
Due to the physical properties of the rubber material, the measurable rubber hardness is subject to a variation that is defined as ± 5° Shore A according to DIN 53505. However, this variation is minimised by our own rubber production.

Type AC-T..F2 – Flange Coupling with Taper Bush

The ARCUSAFLEX® flange coupling type AC-T…F2 is equipped with a taper bush for shaft mounting. The rubber disc element is vulcanized directly to the taper hub. After completion of the assembly, a shrink-fit-like connection, free from backlash is established between the coupling hub with rubber disc element and the shaft. Thanks to the use of commercially available taper bushes with a number of different bore dimensions, the need for finishing the bore and keyway of the coupling hub is omitted for the ARCUSAFLEX® coupling type AC-T. The torque, which can be transmitted, depends on the particular taper bush.

Benefit

Ease of assembly and disassembly with no need for special tools!

Type AC…F2 – Flange Coupling with Bolted Hub

The ARCUSAFLEX® flange coupling type AC…F2 has the rubber disc element vulcanized to a bolt-on sleeve which in turn is bolted to a hub or similar component. Advantage: Depending on the arrangement of the rubber disc element, two different mounting lengths can be achieved using one and the same coupling hub.

Benefit

Depending on the arrangement of the rubber element, two different mounting lengths can be achieved using one and the same coupling hub.

AC…F2K – Flange Coupling for Radial Element Exchange

Type AC…F2K allows the detached element to be replaced without moving the coupled machines, provided that the shaft of the driven machine does not protrude from the coupling hub. Where the flywheel or flywheel housing protrudes excessively from the element, a spacer ring corresponding to oversize X is required for radial removal.
