Before putting the gearbox into service, make sure that:
●
Assembly will not be carried out in a potentially explosive atmosphere (oil, acid, gas, vapour, radiation)
and that dust deposits on the gearbox do not exceed 5 mm in depth.
●
Clean the gearbox thoroughly after installation.
●
The oil level, drain and vent plugs are all easily accessible.
●
All guards designed to prevent accidental contact between operators and rotating parts, and all oil seals,
are fully ef cient.
●
Gearboxes with hollow shafts have been correctly mounted.
●
All types of accessory installed on the gearbox are ATEX speci ed and have been installed in accordance
with ATEX requirements.
During service make sure that:
●
The gearbox is suf ciently ventilated and that it is not subject to radiation from external heat sources.
●
The temperature of the cooling air does not exceed 40°C.
Measuring the gearbox surface temperature
• The gearbox maximum surface temperature depends on motor speed, transmission ratio and motor
version, but must never exceed the value stated on the nameplate.
• The maximum surface temperature speci ed on the nameplate refers to measurements made in normal
ambient and correct installation conditions. Even minimal variations in these conditions (e.g. smaller
mounting compartments) may have a signi cant effect on heat dissipation.
• When putting the gearbox into service, the surface temperature must be measured in the same conditions
as those in which the gearbox will operate. The surface temperature must be measured at the coupling
between the gearbox and motor, and at the points which are most shielded from the forced ventilation
provided by the motor fan.
