5 Maintenance and Inspection
Maintenance and inspection procedures 5-97
［Caution］
・ The brand name of the grease shown in the
Table 5-4 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 sus
-
pended, 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.
･ By the maintenance forecast function of RT ToolBox2 (option) computes the guide of the lubrication hours put
together with the customer's operation status.
・ The numbers in the Table 5-4 correspond to the supply positions in Fig. 5-15 (RV-4F/7F series) or Fig. 5-16
(RV-13F series).
・ When the specified time limit (24,000 Hr) is due, the overhaul work to replace internal grease is required. The
maintenance after it needs the overhaul work which replaces internal grease. Please ask dealer for more details
about overhaul.
(2) Lubrication method
1) Set the robot to the posture shown in Fig. 5-15 (RV-4F/7F series) or Fig. 5-16 (RV-13F series).
2) Refer to the Page 82, "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) ・ RV-4F series
Remove the following screws, and install the attached grease nipples.
SExx01: J2 axis lubrication port <2>, J3 axis lubrication port <3>, J4 axis lubrication port <4>, J5 axis
lubrication port <5>, J6 axis lubrication port <6> (reduction gears) and J6 axis lubrication port <7>
(gear). Securely tighten the grease nipple by 4.7 N·m to 6.3 N·m
SExx02: J3 axis lubrication port <3>, J4 axis lubrication port <4>, J5 axis lubrication port <5>, J6 axis
lubrication port <6> (reduction gears) and J6 axis lubrication port <7> (gear). Securely tighten the
grease nipple by 4.7 N·m to 6.3 N·m
・ RV-7F series
Remove the following screws, and install the attached grease nipples.
SExx01: J2 axis lubrication port <2>, J4 axis lubrication port <4>, J5 axis lubrication port <5>, J6 axis
lubrication port <6> (reduction gears) and J6 axis lubrication port <7> (gear). Securely tighten the
grease nipple by 4.7 N·m to 6.3 N·m
