ARCUSAFLEX

The ARCUSAFLEX coupling is a highly flexible 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
• Ease of assembly thanks to the plug-in type design 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)

ARCUSAFLEX-VSK

The highly torsionally flexible ACRUSAFLEX-VSK coupling is used in a drive train when a large shaft displacement or an extended distance between the drive and the driven components must be compensated. Depending on the arrangement of the drive train components, a non-uniform motion of the speed may result, and since cardan shafts exhibit some torsion flexibility, the mass of the prime mover and driven machine may induce a resonant system.

Advantages of the highly tosrionally flexible ARCUSAFLEX-VSK couplings:

• Linear torsional deflection characteristic
• Elements available in different torsional stiffnesses
• Enhanced damping capacity through frictional damping
• Available in 9 sizes: from 390 Nm to 20.000 Nm
• Maintenance-free coupling bearings
• Radial bearing close to the cardan joint
• •A variety of designs for different cardan shaft configurations
• •Many types with SAE connection dimensions or as specified
• •Compact construction, the highly flexible element being protected by the housing
• •Fail-safe device visible from the outside for ease of inspection

TOK-coupling system

Test bench couplings are applied in miscellaneous test benches. By reason of manifold, specific requirements TOK system is designed according to the modular design concept, to be applicable on almost every engine test bench.

For specific requirements, e.g. special-test benches, the standard parts can be combined with specific-designed parts to derive solutions corresponding to individual conditions.

Advantages of the TOK-ZW coupling system:

• Lowest possible torsional stiffness utilizing two flexible elements
• Simple adjustment of the torsional stiffness by changing of elements
• Compensation of axial-, radial- and angular misalignment
• Self-centering, backlash-free and maintenance-free
• Flanges adapted to DIN or SPICER bolt patterns, respectively on demand
• Variable installation lengths utilizing telescopic spacer shafts
• Ideal for highest speed
• Lowest possible weight by using high-tensile aluminium and CFRP

MULTI CROSS RILLO

MULTI CROSS RILLO couplings are highly torsionally flexible tyre couplings with progressive torsional deflection haracteristic. The salient feature of the MULTI CROSS RILLO shaft couplings is that the coupling hubs are supplied with commercially available taper bushes for nominal torques of up to 11500 Nm. This allows easy and time saving mounting of the coupling hubs on the shaft. Special tools are not required.

The most important attributes and advantages of the highly flexible MULTI CROSS RILLO couplings:

• High torsional flexibility with progressive torsional deflection characteristic
• High compensating capability for axial, radial and angular misalignments
• Easy and time saving mounting of the coupling hubs thanks to the use of taper bushes
• Radial change of the rubber element without axial movement of the coupled machines
• Backlash-free torque transmission even in case of alternating directions of rotation
• High torsional vibration and shock load damping capability
• Noise level insulation
• Wear-resistant and maintenance-free
