Installation Example 1 (Fig. 3)
The Items 7 to 10 are customer-side mounting
parts which are not included in the standard
scope of delivery.
In operation, the armature disk (2) is attracted to the rotor (3).
The torque is transmitted via frictional locking from the drive
shaft (8) via the rotor (3) and the armature disk (2) onto the V-
belt disk (7).
The coil carrier (1) is screwed onto the machine wall, centred
onto the shaft bearing (9).
The air gap "a" between the rotor (3) and the armature disk (2) is
defined via the distance ring (10) between the rotor (3) and the
V-belt disk bearing (7).
The V-belt disk (7) should be made from a material which is a
poor magnetic conductor in order to prevent magnetic loss due
to leaking flux and therefore loss of force.
Installation Example 2 (Fig. 4)
Electromagnetic clutch with flange hub (6) for the connection of
two aligning shafts.
Torque Course:
Input shaft
– rotor (3) – armature disk (2) – flange hub (6) –
output shaft.
The coil carrier (1) and the rotor (3) are mounted input-side, the
flange hub (6) with the screwed-on armature disk (2) is mounted
onto the output shaft.
Axial securement of the rotor (3) takes place via a press cover
and a screw, screwed into the shaft threaded centre hole. A set
screw (6.1) secures the flange hub (6) onto the output shaft. For
adjustment of air gap "a" between the rotor (3) and the armature
disk (2), the set screw (6.1) is loosened and the flange hub (6) is
moved onto the output shaft.
Boring the Rotor Hub (Fig. 2)
Fig. 2
The rotor (3) must not be bent during boring.
Do not place pressure on the outer, thin-walled rotor area, see
Fig. 2.
To bore, clamp on the rotor hub.
The max. permitted bore diameter d
max.
, according to Table 1,
must not be exceeded. The keyway is produced according to
DIN 6885.
We recommend H7/k6 as a suitable hub-shaft tolerance.
