3.16 Output coupling
NOTICE!
Risk of damage to gear unit and motor from poor coupling alignment
• Check the alignment of the coupling prior to commissioning. The coupling must be positioned
according to the installation instructions (specific drawing for the order). If no details are stated, the
coupling must be aligned flush with the end of the motor shaft.
The coupling specifications must always be verified if the operating conditions (power, speed, changes
to the drive or the driven machine) change.
Output couplings which are supplied separately must be fitted and aligned according to the
manufacturer's documentation.
3.17 Internal cooling system (Option: CC)
WARNING
Risk of injury due to pressure discharge
• Ensure that the pressure is released from the cooling circuit before carrying out any work on the
gear unit.
NOTICE!
Risk of damage to the cooling coil
• The cooling coil must not be subjected to external forces.
• Do not twist the connections after assembly.
• Prevent vibrations from reaching the cooling coil during operation.
Information
Using two cooling coils
Make sure when using two cooling coils to connect them in parallel and not in series. This is the
only way to ensure that sufficient cooling power is available.
For the inlet and outlet of cooling fluid, connections with pipe threads are provided on the gear unit or
the casing cover for fitting pipes or hoses. The exact size of the pipe threads can be obtained from the
specific dimension sheet for the order.
Remove the drain plug from the screw neck prior to assembly and flush the cooling coil to
prevent any contamination of the cooling system . The screw necks should be connected with the
coolant circuit, which must be provided by the operator. The flow direction of the coolant is irrelevant.
If a volume regulator is fitted upstream of the cooling coil, the connection is extended accordingly. The
cooling water must be fed in via the volume regulator. Observe the operating instructions of the
volume regulator.
