Coupling (N--EUPEX)
(Flexible couplings N--EUPEX and N--EUPEX--DS,
types A a nd ADS)
· N-- EUPEX couplings provide radial, angular, axial and tor -
sional flexibility. They are positive--locking.
· Torque is transmitted by flexible coupling elements (flexi-
bles).
· The non--linear spring characteristic and the favourable
damping properties of the N--EUPEX coupling effectively
counteract any dangerous increase in vibrations.
General instructions and safety notes
When fitting and removing N--EUPEX couplings please note
the following requirements:
D The coupling shall only be operated,
serviced or repaired by authorized,
skilled and duly qualified staff.
D The coupling shall only be used and
operated within the c onditions
stipulated in the technical specification
and supply contract.
D Unauthorized modification and removal
of protective equipment is not permitted.
D Any work on the coupling shall only be
performed with the machine shut down.
The driver must be secured against
inadvertent start-- up (e.g. by locking the
key--operated switch or removing the
power supply fuses). At the switch--on
point a notice shall be affixed to the
effect that work is being performed on
the coupling.
D Immediately switch off the driver when
changes in coupling behaviour occur,
such as changed running noises.
D The coupling must be suitably protected
against accidental contact.
Installation
-- Design of types A / ADS
The N--EUPEX coupling types A / ADS consist of a coupling
part 1 which houses the flexible coupling blocks (12), the finger
part 3 and the coupling part 2, which bolts onto part 3.
The bolted connection between part 2 and part 3 makes it possi-
ble to separate the coupled machines without axial displace -
ment (if clearance P is observed).

-- Mounting the coupling components
Before fitting the coupling components, carefully clean the shaft
ends and the coupling parts. Make sure to remove the flexible
coupling blocks before cleaning the coupling parts with a sol-
vent.
Heed the manufacturer’s instructions for the use of
solvents.
Use appropriate tools when pulling on the
coupling parts, to prevent damage to the
shaft bearings due to the axial joining force.
Make sure to use suitable lifting tackle.
The shaft ends must not protrude from the hub faces. The cou-
pling is locked in axial direction by means of the set screw or
end plate, as applicable / set screw and end plate, respectively.
The set screws shall only be tightened by
means of a hexagon socket head wrench to
DIN 911, without extension.
Non--compliance with these instructions maycause
the coupling to burst. Danger of life by flying frag-
ments!
