Safety
Proper use
The ARCUSAFLEX series couplings in the AC…F2, AC…D F2, AC…F2K and
AC…D F2K types are used to transmit torques and rotational speeds between a drive
unit and the driven machine in the horizontal position. They reduce torsional vibrations
and shock loads and are able to compensate or misalignments.
Proper use also includes the observance o and compliance with all details contained
in these operating instructions and the related documents. This applies, in particular,
to both the sa ety instructions and the warning notices, and to the adherence to the
cleaning and maintenance intervals.
Any other use or any use beyond the limits o proper use is deemed improper use
and can lead to property damage or personal injury.
The ollowing types o use, in particular, are deemed improper use:
Operating the coupling outside its operating limits, and especially at too high
rotational speeds and/or torques or continuous atigue torques.
Operating the coupling in a substandard condition.
Having the coupling operated by inadequately trained personnel.
Operating the coupling with deactivated and/or modi ied protection devices.
Operating the coupling with modi ied add-on parts.
Improper cleaning with cleaners containing solvents, alkalis or acids.
Improper operation o the coupling results in or eiture o the liability or material
de ects and warranty.

Description
The ARCUSAFLEX series couplings in the AC…F2, AC…D F2, AC…F2K and
AC…D F2K types are used to transmit torques and rotational speeds between a drive
unit and the driven machine in the horizontal position. They reduce torsional vibrations
and shock loads and are able to compensate or misalignments.
The coupling consists o the coupling lange, the coupling hub and the actual lexible
coupling element. A ter assembly, a torsionally lexible connection is established
between the drive unit and the driven machine.

Components
Coupling flange
The coupling lange is bolted to the lywheel on the drive side. The holes required or
this purpose are provided on the circum erence o the coupling lange. Matching
washers, i needed, are included in the scope o supply. Unless otherwise agreed, the
required bolts must be provided by the customer. The coupling lange is designed as
a cast construction and, depending on the coupling size, is made o cast iron or cast
aluminium. The coupling lange is equipped with internal toothing with a cam pro ile.
This internal toothing is the mating part or the external toothing o the lexible
coupling element. The toothing intermeshes by joining the lexible coupling element to
the coupling lange. Under rotation, this results in a practically backlash- ree, positive
connection, which allows or transmission o the torque.
Coupling element
The coupling element consists o a bolt-on sleeve made o steel or a cast sleeve and
a lexible part. Through holes and/or threaded bores are provided in the bolt-on
sleeve. These are used or joining the coupling element to the coupling hub.
Depending on the ambient temperature, the lexible part is either made o a mixture o
natural/synthetic caoutchouc or silicone caoutchouc. The lexible part is vulcanised
directly onto the bolt-on sleeve. The outside diameter o the lexible part is equipped
with toothing with a cam pro ile. This serves to positively trans er the torque in
combination with the coupling lange.
Coupling hub
The coupling hub is usually made o steel. The coupling hub can be supplied
undrilled, pre-drilled or with inished bores and keyways upon the customer's request.
It is mounted on the sha t o the driven machine where it is astened into position. For
this purpose, a threaded bore may be provided on the circum erence. The coupling
element is bolted to the coupling hub. Complete couplings come with matching bolts
which are included in the scope o supply.
With this type, AC…F2 two di erent mounting lengths can be achieved depending on
the con iguration o the coupling element, see page 36.

Description
20
Spacer ring (optional)
The spacer ring (6) is an optional component. It is used to adjust the distance
between the coupling hub (3) and the lexible coupling element (2).
Operating conditions
Depending on the rubber mixture o the lexible coupling element, adhere to the
ollowing operating conditions:
