3.4 Preparing for installation
Inspect the delivery for transport and packaging damage immediately on receipt. The drive unit must
be examined and may only be installed if no leaks are apparent. In particular the shaft sealing rings
and sealing caps must be inspected for damage. Report any damage to the carrier immediately. Gear
units with transport damage must not be commissioned.
All bare metal surfaces and shafts of the geared motor are protected against corrosion with oil, grease
or corrosion protection agents before shipping.
Thoroughly remove all oil / grease or corrosion protection agents and any dirt from the shafts and
flange surfaces before assembly.
In applications where an incorrect rotational direction may result in damage or potential risk, the
correct rotational direction of the output shaft must be established by test running the uncoupled drive
and ensured for subsequent operation.
Gears with integrated back stops are marked with arrows on the drive/driven sides. The arrows point
in the rotation direction of the gear unit. When connecting the motor and during motor control, it must
be ensured that the gear unit can only operate in the direction of rotation.
It must be ensured that no aggressive or corrosive substances which attack metal, lubricants or
elastomers are present in the area surrounding the installation site or are subsequently expected
during operation. In case of doubt, please contact Getriebebau NORD and take the recommended
action.
Oil level tanks (Option: OT) are fitted as standard prior to delivery of the gear unit. If this is not the
case, the intended position can be obtained from the order-related dimension sheet.
Gear units filled with VCI concentrate for long-term storage are fully closed. Take care that the vent is
fitted and released as necessary prior to commissioning. The installation position can be obtained
from the specific dimension sheet for the order.
If possible, the shaft sealing rings or the gear unit should be protected from exposure to direct
sunlight.
3.5 Installing the gear unit
No additional loads must be attached to the gear unit. If a motor is mounted, an existing eye bolt must
not be used for lifting (please see chapter 1 "Safety information").
All bolts must be used to fasten the gear unit.
Pay attention to the following items in order to prevent overheating:
• Ensure a free flow of air to all sides of the gear unit.
• Ensure that there is a free space of 30° around fan intakes.
• With geared motors, the cooling air of the motor fan must be able to flow against the gear unit
without obstruction.
• Do not enclose or encase the gear unit.
• Do not subject the gear unit to highly energetic radiation.
• Do not direct warm exhaust air from other units onto the gear unit.
• The base or flange to which the gear unit is attached must not input any heat into the gear unit
during operation.
• Do not allow dust to accumulate in the area of the gear unit
Please contact NORD if the conditions stated above cannot be met.
The gear unit must be precisely aligned with the drive shaft of the machine in order to prevent
additional forces from being imposed on the gear unit due to distortion.
