Installing An Electric Motor With An Iec Standard Flange - BONFIGLIOLI Riduttori AS Series Installation, Operation And Maintenance Manual

4.3 INSTALLING AN ELECTRIC MOTOR WITH AN IEC STANDARD FLANGE

4.3.1 Thoroughly clean and degrease all the mating surfaces between the motor and the gearbox
(shafts and flanges).
4.3.2 Do not force the surfaces together or use inappropriate tools to couple them. Take care not to
damage the flat and/or cylindrical mating surfaces.
4.3.3 Do not strain the coupling shafts with large thrust or overhung loads.
4.3.4 To facilitate assembly, use a synthetic oil-based lubricating paste such as Klüber paste 46 MR 401 (or a
product with similar properties and application range).
Tighten all the motor/gearbox fixing bolts to their prescribed torques. See the "INSTALLING THE
4.3.5
GEAR- BOX" section in this manual for tightening torque values.
When the gearbox is to be coupled to a standard electric motor conforming to IEC 60072-1, proceed as
follows.
• Apply a layer of sealant such as Loctite 510 (or a product with similar properties and application range)
to the motor/gearbox coupling flanges, to the alignment ring and the frontal mating surfaces as shown in
the figure below.
• With the motor coupled to the gearbox, apply a film of sealant such as Loctite 5366 (or a product with
similar properties and application range) around the edges of the flanges to seal any gaps between their
surfaces.
• If the output shaft is also equipped with a flange, the user must take similar precautions to prevent dust
accumulating in the gaps between the flanges or in the vicinity of moving couplings.
1. Apply Loctite 510 to the flat surface
of the flange and to the alignment
ring.
2. Apply Klüber paste 46MR401 to the
inside of the gearbox input shaft and
to the motor shaft.
3. Seal the join between the gearbox
and the motor with Loctite 5366, tak-
ing care to fill any gaps between the
two flanges (e.g. recesses for decou-
pling the units).
