Maintenance and inspection procedures 5-88
・ The numbers in the
correspond to the supply positions in
.
・When the specified time limit (24,000 Hr) is due, the overhaul work to replace internal grease is required. For the
J1/J2 axis reduction gears, if the overhaul cannot be conducted at the specified timing, lubricate them at the
lubrication interval in
. Please ask dealer for more details about overhaul.
(2) Lubrication method to the J1, J2 axis
1) Turn off the controller's power supply.
2) Refer to the
"Fig.5-3 ： Installing/removing the cover"
and remove the covers.
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.
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.
Note) Sealant is applied to the installation surface of the cover. Be sure to replace the sealant if it has
been dislocated and bent or crushed and does not return to its original shape.
5) If the maintenance forecast function is enable, please reset the accumulated data about grease. Carries out
the resetting operation by RT ToolBox or parameter (MFGRST). Refer to separate "RT ToolBox2 / RT
ToolBox2 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.
(3) Lubrication method to the shaft
1) Refer to
Page 72 "Fig. 5-3: Installing/removing the cover"
, remove the No. 2 arm cover-U.
2) Wipe the old grease off the shaft. Wipe off the grease inside the No. 2 arm cover-U and the bracket
attached vertically to the shaft fixing area.
3) Apply the specified amount of grease to the shaft. If too much grease is applied, grease can spread inside
the No. 2 arm, and if it reaches to the timing belt, can cause the timing belt to deteriorate quicker than
usual.
4) Install the No.2 arm cover U as before.
This completes of applying grease to shaft.
