Reich Type AC…F2 with electromagnetic coupling ARCUSAFLEX ® Highly Flexible Coupling

Advantages -Very high torsional flexibility with a linear torsional deflection characteristic -High torsional vibration and shock load absorbing capability -Backlash-free torque transmission -Ease of assembly thanks to the plug-in type design with ample axial float -Compensation of major misalignments -Torque limitation protecting the drive against overload -ATEX General Technical Description The ARCUSAFLEX ® coupling (short form: AC) is a highly torsionally flexible flange coupling with an axial plug-in facility, providing a torsionally soft connection between an internal combustion engine and a driven machine. 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. Various vulcanisates are available to achieve optimum adaptation to the given application conditions: A natural / synthetic caoutchouc mixture is the standard version for application temperatures of up to 80 °C, more heat resistant mixtures for up to 100 °C / 120 °C and a silicone mixture for higher application temperatures up to 130 °C. The inside diameter of the rubber element is vulcanized directly to a hub body or bolt-on sleeve. The toothed profile on the circumference of the element provides a virtually backlash-free, positive plug-in connection to the coupling flange when in service. The ARCUSAFLEX ® flange coupling series covers a torque range from 210 Nm to 72 000 Nm. Element versions of different dynamic 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. Shaft-to-shaft connections when required can be met by ARCUSAFLEX ® shaft couplings which consist of an ARCUSAFLEX ® flange coupling of the standard design equipped with a second hub. Type approvals from a number of leading classification society have been obtained. If required, couplings complete with a fail-safe device can also be supplied. ARCUSAFLEX ® couplings comply with ATEX explosion protection. They are certified according to directive 2014 / 34 / EU and may be used in hazardous locations (categories M2, 2 + 3). ATEX documentation to supplement the operating instructions is available on request.
