3.6 Cleaning activities
3.6.1. Flushing a contaminated gearbox
Different types of oil
As the Shell Tivela S 150 (Kyodo Yushi TMO 150)is not compatible with mineral oil,
contamination with other types of oils used in the gearboxes is not accepted. Equipment used
in handling of Tivela S 150 (Kyodo Yushi TMO 150) must be carefully cleaned.
This section details how to flush the primary gears of axis 4 and 5, and the gearbox of axis 6
in case of contamination with other type of oil.
Required equipment
Service program
Create a program with motions on axis 3, 4, 5 and 6. There is no need to remove the tool and
equipment installed on the robot if the Service program can be created and is possible to run.
Recommended motion
•
axis 3: ± 15 degrees
•
axis 4-6: maximum working range with regard to the installation (limitation: axis 4
and 5: ± 90 degrees, axis 6: ± 180 degrees).
Draining the gearbox properly
The contaminated gearbox must be drained properly before and during the flushing
procedure:
•
Axis 4 gearbox: open both oil plugs (filling and draining) and run axis 3 in different
directions. Draw out the last volume (approx. 40 –60 ml) by using a syringe with a
prepared hose end.
•
Axis 5 gearbox: open both oil plugs (filling and draining) and run axis 4 back and
forward until the oil draining has stopped.
•
Axis 6 gearbox: open both oil plugs (filling and draining) and run axis 5 and 6 in
different directions until the oil draining has stopped.
