3 Maintenance
3.5.1. Oil change, gearbox, axes 5 and 6
WARNING!
Please observe the following before commencing any repair work on the manipulator:
TIP!
When changing gearbox oil, first run the robot for a time to heat up the oil. Warm oil drains
quicker than cold oil.
WARNING!
When filling gearbox oil, do not mix different types of oil unless specified in the instruction.
Always use the type of oil specified by the manufacturer!
WARNING!
When filling gearbox oil, do not overfill, since this could lead to internal over-pressure inside
the gearbox which in turn may:
WARNING!
Changing and draining gearbox oil may require handling hot oil of up to 90 °C! Make sure
that protective gear like goggles and gloves are always worn during this activity.
Also, be aware of possible pressure build up in gearbox! When opening the oil plug, there
may be pressure present in the gearbox, causing oil to spray from the opening!
Draining, axes 5 and 6
The procedure below details how to drain the oil from gearboxes, axes 5 and 6.
Step
74
• Motors and gears are HOT after running the robot! Touching the motors and gears may
result in burns!
• Turn off all electric power, hydraulic and pneumatic pressure supplies to the robot!
• Take any necessary measures to ensure that the manipulator does not collapse as parts
are removed, e.g. secure the lower arm with fixtures if removing motor, axis 2.
• damage seals and gaskets
• completely press out seals and gaskets
• prevent the manipulator from moving freely
Action
1. Move the robot to a position where the upper arm is
close to horizontal and axis 4 in the calibration
position.
2. Remove the oil plugs.
The cavity behind the plugs, containing the oil, is
common to gearboxes 5 and 6, but during draining,
both must be removed.
3. Move axis 4 90° to a position where the axis 6 oil plug
faces downwards.
4. Drain the oil from the gearbox.
5. Move axis 4 another 90°.
6. Refit the oil plug.
