Components
Coupling flange
The coupling flange is bolted to the flywheel on the drive side. The holes required for
this purpose are provided on the circumference of the coupling flange. Matching
washers, if needed, are included in the scope of supply. Unless otherwise agreed, the
required bolts must be provided by the customer. The coupling flange is designed as
a cast construction and, depending on the coupling size, is made of cast iron or cast
aluminium. The coupling flange is equipped with internal toothing with a cam profile.
This internal toothing is the mating part for the external toothing of the flexible
coupling element. The toothing intermeshes by joining the flexible coupling element to
the coupling flange. Under rotation, this results in a practically backlash-free, positive
connection, which allows for transmission of the torque.
Coupling element
The coupling element consists of a bolt-on sleeve made of steel or a cast sleeve and
a flexible part. Through holes and/or threaded bores are provided in the bolt-on
sleeve. These are used for joining the coupling element to the coupling hub.
Depending on the ambient temperature, the flexible part is either made of a mixture of
natural/synthetic caoutchouc or silicone caoutchouc. The flexible part is vulcanised
directly onto the bolt-on sleeve. The outside diameter of the flexible part is equipped
with toothing with a cam profile. This serves to positively transfer the torque in
combination with the coupling flange.
Coupling hub
The coupling hub is usually made of steel. The coupling hub can be supplied
undrilled, pre-drilled or with finished bores and keyways upon the customer's request.
It is mounted on the shaft of the driven machine where it is fastened into position. For
this purpose, a threaded bore may be provided on the circumference. The coupling
element is bolted to the coupling hub. Complete couplings come with matching bolts
which are included in the scope of supply.
With this type, AC…F2 two different mounting lengths can be achieved depending on
the configuration of the coupling element, see page 36.
