Type AC…F2

Flange coupling

The ARCUSAFLEX® flange coupling type AC…F2 has the rubber element vulcanized to a bolt-on sleeve which in turn is bolted to a hub or similar component.

Flange coupling with hub

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

Type AC…F2K

Flange coupling

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.

Flange coupling for radial element exchange

Advantage: Changing element without having to move the coupled machines possible!

Type AC…D F2

Flange coupling

with hub and two coupling elements operating in tandem.

Flange coupling

Shaft coupling

Type AC…D TK

Shaft coupling

with two hubs and two coupling elements operating in tandem.

Shaft coupling

Type AC…F2 DS

Flange coupling

with fail-safe device (get-you-home-device), to be mounted between an internal combustion engine and a marine gearbox.

Flange coupling

Type AC…F2 with splined taper bush

Flange coupling

to be mounted between an internal combustion engine and a pump drive.

Flange coupling with splined taper bush

Type AC…F2 with electromagnetic coupling

Flange coupling

To disconnect the drive.

Flange coupling with external flange housing and integrated electromagnetic coupling

Type AC-T…F2

Flange coupling

The ARCUSAFLEX® flange coupling type AC-T…F2 is equipped with a taper bush for shaft mounting.

The rubber element is vulcanized directly to the hub body of the taper bush. After completion of the assembly, a shrink-fit-like connection, free from backlash is established between the coupling hub with rubber 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…F2. The torque, which can be transmitted, depends on the particular taper bush.

Flange coupling with taper bush

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

Type D2C “Your design”

Designed to Customer

The guiding principle of Designed to Customer is the recipe for success behind REICH. In addition to the catalogue products, we supply our customers with couplings developed to their specific requirements. The designs are mainly based on modular components to provide effective and efficient customer solutions. The special nature of our close cooperation with our partners ranges from; consulting, development, design, manufacture and integration to existing environments, to customer-specific production, logistics concepts and after-sales service - worldwide. This customer-oriented concept applies to both standard products and production in small batch sizes.

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.

The technical data applies only to the complete coupling or the corresponding coupling elements. It is the customer’s/user’s responsibility to ensure there are no inadmissible loads acting on any of the components. In particular, existing connections, e.g. bolted connections, must be checked with regard to the torques to be transmitted. If necessary, further measures, such as additional reinforcement with pins, may be necessary It is the customer’s/ user’s responsibility to make sure the dimensioning of the shaft and keyed or other connection, e.g. shrinking or clamping connection, is correct. All components that can rust are protected against corrosion as standard.

REICH have an extensive range of couplings and coupling systems to cover nearly every drive configuration. Customized solutions can be developed and manufactured even in small batches or as prototypes. In addition calculation programs are available for all necessary dimensioning.
