5.1

INSTALLING THE GEARBOX

All phases of installation and maintenance must be taken into consideration from the machine
design stage. Design personnel must, if necessary, implement a safety plan to protect the health
and safety of all persons directly involved and to ensure the rigorous application of all relevant
legislation.
It is essential for impact and stress to be avoided during the installation process.
Before installing a gearmotor, also refer to the instructions contained in the installation and user manual
for the electric motor.
Before installing the gearbox:
1. Drain out the oil used for storage if it is not the same as the oil used for normal functioning, and flush
the inside of the gearbox out thoroughly (see the "LUBRICATION" section in this manual).
2. Carefully remove all packaging and protective coatings from the gearbox suitable solvents. Take
special care when cleaning mating surfaces. Avoid getting solvents on the shaft seal rings.
3. Check that the data on the nameplate correspond to those specified in the order.
4. Ensure that the structure in which the gearbox is to be mounted is sufficiently robust and rigid to support
its weight and operating forces. If normal service is likely to involve impacts, extended overloads or
possible seizures, fit the necessary hydraulic couplings, clutches, torque limiters, etc..
5. Check that the machine in which the gearbox is to be installed is switched off and cannot be accidentally
started up.
6. Check that all coupling surfaces are flat.
7. Check that the shaft/shaft or shaft/ bore are perfectly aligned for coupling.
8. Fit suitable guards to prevent accidental contact with rotating parts outside the gearbox.
9. If the work environment is corrosive for the gearbox or any of its parts, follow the special precautions
required for aggressive environments. Contact the manufacturer's technical assistance service for
further details.
10. We recommend applying a protective paste such as Klüberpaste 46 MR 401 (or a product with
similar properties and application range) to all key type couplings to ensure optimal coupling
and protection against fretting corrosion. Clean all friction couplings thoroughly but do not
apply any protective pastes to them.
11. Thoroughly clean all other contact surfaces (feet, flanges, etc.) and apply a suitable protective product
to them to prevent oxidation.
12. Mechanical organs keyed on to the solid gearbox output shafts must be machined to an ISO H7
tolerance to prevent couplings from seizing and to prevent irreparable damage to the gearbox during
installation. To ensure effective coupling, driven shafts should be machined to the tolerances specified
in the "PREPARING CUSTOMER SHAFTS" section in this manual.
13. In outdoor installations, protect the gearbox and its motor from direct sunlight and inclement weather
by means of canopies or covers. Make sure that the assembly is properly ventilated.
14. Make sure that the casing of the gearbox is connected to the equipotential protection (earth/ground)
circuit of the machine in which it is installed.
15. Evaluate whether accessible surfaces may exceed the temperature limits established in EN ISO
13732-1 on the basis of the gearbox conditions of use and ambient temperatures; if these limits can
be easily reached or exceeded, the surfaces in question must be protected to prevent contact (by
means of guards and/or lagging). Wherever impossible, signs bearing symbol 5041 of IEC standard
60417 "Warning! Hot surfaces" must be displayed in such a way that they are clearly visible to
machine operators (bearing in mind the position and orientation of the gearbox). Refer to chapter
"ALLOWED TEMPERATURE LIMITS" for further details.
