5.1 INSTALLING

5.1.1 GEAR UNIT

The necessary clearances around the gear unit for installation and subsequent
maintenance work must be planned during the design phase.
If the gear unit is equipped with a fan adequate space must be provided for air
circulation.
Installation must be performed with care by skilled personnel. During the installation
procedure avoid all impact and forcing since this could cause damage to the internal
parts of the gear unit. We cannot be held liable for damage caused by incorrect
installation.
The person authorised to do the work must, if necessary, implement a safety plan to
safeguard all persons directly involved and rigorously apply all applicable legislation.
If a gearmotor is going to be installed, please consult the owner's manual of the electric motor
on beforehand.
Before installing the unit:
Thoroughly clean all packaging materials and protective product residue from the gear unit. Pay
particular attention to the coupling surfaces.
Check that the data on the nameplate corresponds to that which is specified on the order.
Ensure that the structure to which the gear unit is to be mounted is sufficiently robust and rigid to
support its weight and operating stresses.
Check that the machine on which the gear unit is to be installed is switched off and cannot be
accidentally switched on again.
Check that the surfaces on which the gear unit is to be installed are perfectly flat and level. Any
irregularities in the supporting surfaces may result in the transmission of tension to the outer
structure of the gear unit when the fixing bolts are tightened, with possible repercussions also on
the smooth running of the gears.
Check that all coupling surfaces are flat.
Fit suitable guards to protect against the external moving parts of the gear unit.
Check that there are no substances present in the place of installation that could cause
corrosion of the gear unit or its component parts. If there are any aggressive substances in the
environment, this situation must be communicated to the BONFIGLIOLI technical-sales service,
which will provide suitable instructions.
If the gear unit is to be installed outdoors it must be protected from direct sunlight and inclement
weather by installing shields or guards, without impairing ventilation around the unit.
We recommend applying a protective paste to all couplings between the gear unit/motor and
other parts (Klüberpaste 46 MR 401 or equivalent product with similar properties and application
range) to ensure optimal coupling and protection against fretting corrosion.
To ensure effective coupling, the driven shafts should be machined to the tolerances given in
tables in Annex 3 of this Manual.
