7.1. SPLASH LUBRICATION
Splash lubrication is standard for horizontal shaft gear units with one, two and three stages and for speeds
between 750 min
-1
and 1800 min
-1
at the high speed shaft.
Splash lubrication is standard for horizontal shaft gear units with four stages and for speeds between 1000
min
-1
and 1800 min
-1
at the high speed shaft.
All gears and output shaft bearings are lubricated by immersion in the oil bath. Oil splash from gears fill oil
pockets in the housing, assuring gravity circulation lubrication of the bearings via channels in housing and
covers.
For other speeds at the high speed shaft, refer to Hansen Industrial Transmissions nv.
7.2. FORCED FEED LUBRICATION
All rotating elements above oil bath level are lubricated by a gear pump forcing the oil through pressure lines.
Pumps can be either of the integral type, driven by one of the gear unit shafts, or a motorpump.
The integral type pumps are always provided with a built-in reversing device for operation in both directions.
Built-on pumps reach their normal operating capacity already after a few seconds.
In case of motorpumps the direction of rotation is always indicated.
Motorpumps should be switched on at least one minute before starting the gear unit.
7.2.1. Circulation lubrication
- With integrated pump (fig.4).
The circulation lubrication system consists of
- a pump P
- a filter F with bypass (standard from gear unit size G onwards)
- a flow switch Mf (standard from gear unit size G onwards)
Flow switch must be wired in a circuit to automatically stop the main drive motor when oil flow drops
below alarm setting.
However, in order to avoid unwanted alarms during the start-up period, in operation or due to irregularities of
the oil flow, we recommend retarding the alarm signal; the alarm should be triggered only after the oil flow has
been interrupted for a continuous period of 5 seconds.
- With motorpump
The service manual of the lubrication and cooling system gives detailed information about the circulation
lubrication system with motorpump.
7.2.2. Pressure lubrication
The service manual of the lubrication and cooling system gives detailed information about the pressure
lubrication system.
