Maintenance and inspection procedures
［Caution］
・ The brand name of the grease shown in the
is the grease put in at shipping.
・ The lubrication interval 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 interval will fluctuate, so determine the time according to
the state so that the grease does not run out.
･ By the maintenance forecast function of RT ToolBox3 (option) computes the guide of the lubrication hours put
together with the customer's operation status.
correspond to the supply positions in
・Because excessive lubrication leads to the grease leak, avoid it. And the number of times of lubrication limits to
3 times. The maintenance after it needs the overhaul work which replaces internal grease. Contact the dealer.
■ Lubrication method
1) Set the robot to the posture shown in
.
2) Refer to
Page 100, "5.3.2 Installing/removing the cover"
, and remove the covers.
3) Please protect the timing belt with the cloth etc. so that the grease does not take for the timing belt at the
time of oil supply.
4) J5 axis lubrication port <5>, the J6 axis lubrication port <6> (reduction gears), and the J6 axis lubrication port
<7> (gear) should remove the bolt, and should install the attached grease nipple. Securely tighten the grease
nipple by 4.7 Nm to 6.3 Nm.
5) Insert the grease shown in
using a grease gun from the lubrication grease nipple.
6) J5 axis lubrication port <5>, the J6 axis lubrication port <6> (reduction gears), and the J6 axis lubrication port
<7> (gear) should remove the grease nipple, and should install the original bolt. Securely tighten the bolt by 4.7
Nm to 6.3 Nm.
7) Replace the covers with the removal procedure in reverse.
8) 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).
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, following hand grease gun is recommended.
Recommended grease gun: KH-120 (amount: 140ml)
(manufacture: Yamada Corporation Inc.,)
The KH-120 comes with a short nozzle (HSP-1) as standard. If this short nozzle
does not reach the desired areas, depending on installation location, it may be useful
to use a long nozzle (HSP-2). CH-400 has a long nozzle as standard equipment.
