Installing Connecting Elements; Gear Unit Testing And Start-Up - BONFIGLIOLI HDP Series Installation Use And Service Manual

5.3 INSTALLING CONNECTING ELEMENTS

Use the utmost caution when installing the various components, to ensure that no damage is caused
to the gear unit and its parts, such as oil seals and mating surfaces, or internal parts such as gears
and bearings.
To perform the installation operations correctly ensure you have access to suitable lifting
equipment.
When installing external transmission parts do not use hammers or other unsuitable
tools, to avoid the risk of damaging the gear unit shafts and supports.
When installing connecting elements it is advisable to preheat them, taking care to:
Adopt protection against contact with hot parts: risk of burns!
Protect the oil seals from damage and accidental overheating to avoid impairing their
functionality (use a heat shield to protect against irradiated heat).
The connecting or transmission elements must not transmit external loads to the
shafts unless said loads have been calculated at the time of gear unit selection.
If the element to be coupled to the shaft is not fixed in an axial direction by the mechanical interference
of the coupling, utilise suitable retaining components able to prevent axial movement of the element in
question on the shaft.

5.4 GEAR UNIT TESTING AND START-UP

The gear unit has been factory tested by the Manufacturer.
Before starting the unit, check that:
The machine incorporating the gear unit complies with the provisions of the "Machinery
Directive" 98/37/EC and any other applicable safety legislation.
The gear unit's mounting position in the installation corresponds to that prescribed and
indicated on the nameplate.
The electrical power supply and control systems are suitable and operational as stipulated in
standard EN 60204-1, and grounded as per standard EN 50014.
The motor power supply corresponds to that prescribed and is within ± 5% of the rated value.
The oil level is as prescribed and that there are no leaks from the caps or gaskets.
Before starting the gear unit read this handbook carefully. For correct operation of the gear unit it is
essential to comply strictly with the indications and prescriptions contained herein concerning correct
storage, use, and maintenance.
Check that the gear unit and any installed accessories that require oil, are filled to the correct level
after having connected all parts and accessories that were previously removed for shipment.
In the presence of optional accessories it is also necessary to check that all the operations required for
their correct functioning have been carried out as described in the relative chapters. When the gear
unit is started for the first time it must run for at least 8 hours in no load conditions. If no irregular
operation is noted during this period, the load can be gradually increased to the rated operating
conditions over a reasonable period of time during which the gear unit must be monitored closely.
