3.4.2 Changing the oil, axis 1 gearbox on floor mounted robots
Floor mounted or suspended robot
Depending on whether the robot is floor mounted or suspended, the method of
changing the oil differs.
This section describes how to change the axis-1 gearbox oil in a floor mounted
robot. If the robot is suspended, see
Changing the oil, axis-1 gearbox on suspended
robots on page 158 .
Different versions of the gearbox
There are two different versions of the axis-1 and axis-2 gearboxes. The different
versions affect the mechanical structure of the base, frame and lower arm.
Differences in the mechanical structure are pointed out in the procedure as valid
for different robot version:
• IRB 2600-20/1.65, IRB 2600-12/1.65, IRB 2600-12/1.85, IRB 2600ID-15/1.85,
IRB 2600ID-8/2.0
• IRB 2600 Type C-20/1.65, IRB 2600 Type C-12/1.65
Further information about the differences are given in Non-compatible versions of
axis-1 and axis-2 gearboxes on page 428 .
Location of oil plugs
The axis 1 gearbox is located between the frame and base of the robot.
The oil plugs are shown in the figure.
IRB 2600-20/1.65, IRB 2600-12/1.65, IRB 2600-12/1.85, IRB 2600ID-15/1.85, IRB 2600ID-8/2.0
