Every bevel gearbox comes with lubricant which allows the proper
functioning of transmission. Those with a “put oil” label are an
exception. For these, the installer must fill the lubricant up to the
given level and must do so when the gears are not in motion. It is
recommended to avoid overfilling to prevent overheating, noise,
increases of the internal pressure and loss of power.
If necessary, the gearbox may be put in operation at maximum load
immediately. If circumstances allow it, it is recommended to let it
work with an increasing load and reach the maximum load after 20-30
hours of operation. Every precaution must be taken in order to avoid
overloading in the early stages of operation. Temperatures reached by
the gearbox in these early stages will be higher than they will be after
breaking it in.
The selector switch, present on the RIS model, must be handled only
when the transmission is stopped.
1.2.6 Failure of the power supply
Bevel gearboxes transmissions are reversible; therefore the reverse
motion is possible. Pay attention to all the consequences that could
arise from this event.
1.3.2 Risk of break-up during operation
The bevel gearbox, if properly sized as specified in the general catalog
(taking care to never exceed the indicated maximum power and torque
values), may fail during the operation due to a deterioration of its
constituent components, both fixed and mobile.
The causes of damage may be different:
a) Deficiency or deterioration of internal components lubrication:
the oil used for the lubrication of the internal components must be
completely replaced after 3.000 hours of operation. In the presence
of leakage it is necessary a top-off the lubricant, bringing the
quantity back to the factory values (in the table below).
