Highly flexible rubber disc flywheel coupling with an axial plug-in facility, providing a torsionally soft connection between an internal combustion engine and a driven machine.
Advantages of the highly flexible ARCUSAFLEX coupling:
- Very high torsional flexibility with a linear torsional deflection characteristic
- Backlash-free torque transmission
- Available in many different versions
- Available in 15 sizes: from 200 Nm to 110000 Nm
- Temperature Range: -60°C – 130°C
- 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
- Compliant with EU regulation 94/9/EG (ATEX 95)
The highly flexible torque transmission characteristic 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 ilicone mixture.
The ARCUSAFLEX flywheel coupling series covers a torque range from 200 – 110000 Nm (corresponding to approx. 6500 kW at 1000 rpm). Element versions of different torsional stiffnesses are available for optimizing the torsional vibration range.
The flange connection dimensions of ARCUSAFLEX couplings comply predominantly with the SAE J 620 and DIN 6281 standards. Other flange dimensions or overall lengths can be provided on request.
ARCUSAFLEX type AC-T with Taper Bush
The ARCUSAFLEX flywheel 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. Advantage: Ease of assembly and disassembly with no need for special tools!
ARCUSAFLEX Type AC…F2 with Bolted Hub
The ARCUSAFLEX flywheel 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..
