5-60 Maintenance and inspection procedures
5 Maintenance and Inspection
[Caution]
•The brand name of the grease shown in the
Table 5-8 is the grease put in at shipping.
•The lubrication time is a cumulative value of the operation at the maximum speed. If the operation has been
suspended, or if the designated speed is slow, the lubrication time can be lengthened in proportion.
•Depending on the robot operation state, the lubrication time will fluctuate, so determine the time according
to the state so that the grease does not run out.
For the shaft, the lubrication interval should be shorter than one in
Table 5-8 when the operation is
repeated with a short stroke.
•By the maintenance forecast function of RT ToolBox3 (option) computes the guide of the lubrication hours
put together with the customer's operation status.
•The numbers in the Table 5-8 correspond to the supply positions in Fig. 5-6 .
(2) Lubrication method to the J1, J2 axis
1) Then, turn off the controller's power supply.
2) Refer to
Page 52, "5.3.2 Installing/removing the cover", and remove the covers necessary.
3) Insert the grease shown in Table 5-8 using a grease gun from the lubrication grease nipple. Apply the
specified amount of grease. Too much lubrication causes grease leakage.
Use manual grease gun, and inject grease with pressure 0.03Mpa or less. Do not
use the grease gun, which derived by the factory air presser to avoid injecting by
too high pressure.
A grease gun that fits the grease nipple is required.
Recommended grease gun: KH-120 (capacity: 140 ml) or KH-32 (capacity: 200 ml)
(manufacturer: Yamada Corporation)
The above-mentioned grease gun comes with a short nozzle (HSP-1) as standard.
If this short nozzle does not reach the desired areas, depending on the robot model
and installation location, it may be useful to use a long nozzle (HSP-2).
4) Install the covers with the removal procedure in reverse.
5) If the maintenance forecast function is enable, please reset the accumulated data about grease. Carries
out the resetting operation by RT ToolBox3 (option) or parameter (MFGRST). Refer to separate "RT
ToolBox3 / RT ToolBox3 mini User's Manual" for the operation method of RT ToolBox, and refer to
separate "Instruction Manual/Detailed Explanation of Functions and Operations" for details of parameter
(MFGRST).
The lubricating to J1 and J2 axes is completed.
