Procedure
Filling the planetary gearbox with lubricating oil using the supplied connecting
piece (supplied loose) via the valve mounted in the ring gear:
Please observe the adjacent sketch.
• Bore Z: for filling the lubricating oil
• Bore 6: for checking the lubricating oil
• Oil inlet valve / oil drain valve 13: installed in the planetary gearbox
• Connecting piece 14: supplied loose
Release the brake with the air pressure specified in the technical data in the
dimensioned drawing in order to be able to turn the ring gear / rope drum. Make
sure that the maximum ventilation pressure of 50 bar is not exceeded. See
appendix D "Technical data / drawings" of the material-number-specific operating
instructions.
1
Place a container with sufficient capacity under the planetary gearbox.
2
To fill in oil, turn the rope drum until the oil inlet valve / oil drain valve 13 can
be seen through the opening Z for oil inlet in the spindle (at 12 o'clock).
3
Unscrew the protective cap from the oil inlet valve / oil drain valve. Observe
appendix F "Optional equipment variants" of the material-number-related
operating instructions.
4
Screw the supplied connecting piece 14 onto the oil inlet valve / oil drain valve.
5
The valve is open.
6
Loosen and then remove the screw plug from bore 6.
7
Fill the planetary gearbox with clean lubricating oil using the supplied
connecting piece 14. Fill sufficient lubricating oil until some oil drains from
bore 6.
8
Then unscrew the supplied connecting piece 14.
9
The oil inlet valve / oil drain valve 13 is closed.
10
Then screw the protective cap back onto the oil inlet valve / oil drain valve 13
hand-tight.
11
Check whether the seal on the screw plug thread of the bore 6 is still in perfect
condition and can be reused. Replace a damaged seal.
12
Seal bore 6 with the corresponding screw plug.
13
Let the MOBILEX GFT-W planetary gearbox run for approx. 5-10 minutes.
14
Allow the planetary gearbox to cool down to approx. 50°C after switching off.
15
For checking the oil level, loosen the screw plug of the bore 6 slowly, so that
any existing pressure can be released. Then remove the screw plug again from
bore 6. The oil level is correct if some lubricating oil escapes from the bore 6
when the planetary gearbox is at standstill.
16
If the oil level is too low, repeat steps 1 to 10. Fill sufficient lubricating oil until
it drains from bore 6.
17
Check whether the seal on the screw plug thread of the bore 6 is still in perfect
condition and can be reused. Replace a damaged seal.
18
Seal bore 6 with the corresponding screw plug.
