Gear Unit With Cooling Coil Or External Oil­supply System; Temperature Measurement; Bearing Monitoring (Vibration Measurement); Removal From Service - Siemens FLENDER B3 E Series Assembly And Operating Instructions Manual

7.2.2 Gear unit with cooling coil or external oil­supply system
For technical data, refer to the data sheet and/or the list of equipment.
Fully open the stop valves in the coolant in­ and outflow pipes.
After starting up the external oil­supply system for the first time the oil level must be
once more checked in accordance with item 7.2.1.
7.2.3

Temperature measurement

During first start­up and after maintenance work, the oil­sump temperature must be
measured during correct use (maximum machine performance) after appropriate
running in.
The maximum permissible oil­sump temperature is 90 °C.
At higher temperatures the gear unit must be shut down immediately and Siemens
customer service consulted.
7.2.4

Bearing monitoring (vibration measurement)

If the necessary measures have been made for vibration measurement as bearing
monitoring (see item 5.15.2), vibration measurements must be taken in order to obtain
initial values and/or standard values for the diagnosis. These measurements must be
recorded and filed.
7.3

Removal from service

To take the gear unit out of service, first switch off the drive assembly.
Secure the drive unit to prevent it from being started up unintentionally.
Attach a warning notice to the start switch!
In case of gear units fitted with cooling coil or water oil­coolers, close the stop valves on the water in­
nd outflow pipes. To prevent freezing, drain the water from the cooling coil or the water oil­cooler.
Start the gear unit and allow it to run briefly (5 to 10 minutes) approx. every 3 weeks (during a shut­down
period no longer than 6 months).
Treat the gear unit with preservative, see items 7.3.1 and 7.3.2 (before a shut­down period exceeding
6 months).
7.3.1

Interior preservation during longer disuse

Depending on the type of lubrication and/or shaft sealing, the following types of interior preservation can
be applied.

7.3.1.1 Interior preservation with gear oil

Gear units with splash­lubrication systems and contacting shaft seals can be filled with the correct type of
service oil up to a point just below the air filter.
