4.7 Checking the gear unit
During a test run under full load, the gear unit should be checked for:
 Unusual noises, such as grinding, knocking or rubbing noises
 Unusual vibrations, oscillations or other movements
 Production of steam or smoke
After the test run, the gear unit should be checked for:
 Leaks
 Slippage of the shrink disks. For this, the cover should be removed and a check carried out
whether the marking described in Section 3.12 shows a relative movement of the hollow shaft
of the gear unit and the machine shaft. Then the cover should be fitted as described in
Section 3.13.
Hinweis!
Shaft sealing rings are rubbing seals and have sealing lips made from an elastomer
material. These sealing lips are lubricated with a special grease at the factory. This
reduces the wear due to their function and ensures a long service life. An oil film in the
region of the rubbing sealing lip is therefore normal and is not due to leakage.
Danger!
The drive must be shut down and Getriebebau Nord consulted if any irregularities are
observed during the checks described above.
