Maintenance and inspection procedures
■ Lubrication method to the J1, J2 axis
1) The positions of lubrication ports are shown in the
. Move the robot to the posture in which it can
supply the grease easy.
2) Refer to
Page 101, "5.3.2 Installing/removing the cover"
, and remove the covers necessary.
3) Insert the grease shown in
using a grease gun from the lubrication grease nipple. Add only the
specified amount of grease. Adding excess grease may cause grease to leak. The J1 axis grease lubrication
port is positioned near the timing belt. If the grease is adhered to the belt, wipe it off, although the belt is
resistant to grease.
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: CH-400 (manufacture: Yamada Corporation Inc.,)
The CH-400 gun is a cartridge-type grease gun. Contact your dealer and use com
-
mercially available grease cartridges.
When a grease can is used, hand grease gun KH-32 (manufacture: Yamada Corpora
-
tion) is recommended. The KH-32 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). CH-400 has a long
nozzle as standard equipment.
4) Install the removed cover as before.
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 ToolBox3, 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.
■ Lubrication method to the shaft
1) Refer to
Page 101, "5.3.2 Installing/removing the cover"
, and remove the motor cover J3.
2) Wipe the old grease off the shaft. At this time, wipe off the grease that has been scattered inside the motor
cover J3 and the bracket attached vertically to the shaft fastening area.
3) Apply the specified amount of grease to the shaft. If too much grease is applied, grease may get scattered
all over inside of the No. 2 arm. If the grease reaches the timing belt inside the No. 2 arm, the timing belt
may deteriorate prematurely.
4) Install the covers with the removal procedure in reverse.
The applying grease to shaft is completed.
