GeneralTechnical Description
The ARCUSAFLEX ® coupling (short form:AC) is a highly torsionally flexible flange coupling with an axial plug-infacility, providing a torsionally soft connection between an internalcombustion engine and a driven machine. The highly flexible torque transmissioncharacteristic is achieved by a disc-shaped rubber element that is subjected toa torsional load and enables both the absorption of high torsional vibrationsand the compensation of major misalignments. Various vulcanisates are availableto achieve optimum adaptation to the given application conditions: A natural /synthetic caoutchouc mixture is the standard version for applicationtemperatures 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.
Theinside diameter of the rubber element is vulcanized directly to a hub body orbolt-on sleeve. The toothed profile on the circumference of the elementprovides a virtually backlash-free, positive plug-in connection to the couplingflange when in service.
TheARCUSAFLEX ® flange coupling series covers a torque range from 210 Nm to 72 000Nm. Element versions of different dynamic torsional stiffnesses are availablefor optimizing the torsional vibration range. The flange connection dimensionsof ARCUSAFLEX ® couplings comply predominantly with the SAE J 620 and DIN 6281standards. Other flange dimensions or overall lengths can be provided onrequest.
Shaft-to-shaftconnections when required can be met by ARCUSAFLEX ® shaft couplings whichconsist of an ARCUSAFLEX ® flange coupling of the standard design equipped witha second hub. Type approvals from a number of leading classification societyhave been obtained. If required, couplings complete with a fail-safe device canalso be supplied.
ARCUSAFLEX® couplings comply with ATEX explosion protection. They are certified accordingto directive 2014 / 34 / EU and may be used in hazardous locations (categoriesM2, 2 + 3). ATEX documentation to supplement the operating instructions isavailable on request.
