Robots performing certain, extremely
heavy duty work cycles may be fitted with
vented oil plugs. These are not fitted to
normal duty robots, but can be pur-
chased from your local ABB representat-
ive.
Too hot gearbox oil may be caused by:
• Incorrect oil quality or level.
• The robot work cycle runs a specific
axis too hard. Investigate whether it
is possible to program small "cooling
periods" into the application.
• Overpressure created inside gearbox.
