Note1) When the screw is installed in the illustrated lubrication point, install the attached grease nipple and supply the grease.
Note2) Since RV-4FRJL is 5-axis type robot, they have no J4 axis reduction gears.
［Caution］
・ The brand name of the grease shown in
・ 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.
・ The numbers in
Table 5-11
(RV-13FR series).
・ When the specified time limit (24,000 Hr) is due, the overhaul work to replace internal grease is required. If the
overhaul cannot be conducted at the specified timing, lubricate them at the lubrication interval in
For the overhaul, contact the dealer.
■ Lubrication method
1) Set the robot to the posture shown in
2) Refer to the
Page 100, "5.3.2 Installing/removing the cover"
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-4FR series
Remove the following screws, and install the attached grease nipples.
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).
* RV-4FRJL does not use the J4 axis lubrication port <4>. Securely tighten the grease nipple by 4.7 N·m to
6.3 N·m
・ RV-7FR series
Remove the following screws, and install the attached grease nipples.
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-13FR series
Removes J1 axis waste oil screw <1>, the J2 axis waste oil screw <3>, and the J3 axis waste oil screw <5>.
Because the oil appears from the screw hole, please wipe off with the rag etc.
Remove the screw of from J1 axis lubrication port <2> to the J6 axis lubrication port (gear) <7>, and install
the attached grease nipple. Securely tighten the grease nipple by 4.7 N·m to 6.3 N·m
5) Insert the grease shown in
