3. Inject the grease through the grease inlet using a grease gun
– Grease type: Molywhite RE No. 00
–
Amount of grease: approx. 1550 cc
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less
4. The grease exchange is completed when new grease appears in the
g
rease exhaust port. (The new grease can be distinguished from the
old grease by color.)
5. Move the R-Axis for a few minutes t
o discharge excess grease.
6. Wipe the discharged grease with a cloth, a
nd reinstall the plug. Before
installing the plug, apply Three Bond 1206C on the thread part of the
plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
7. Remove the grease zerk from the grease inlet, and reinstall the plug.
Before ins
talling the plug, apply Three Bond 1206C on the thread part
of the plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
9.3.4.7 Grease Exchange for B-Axis Speed Reducer
(
Refer to Fig. 9-7 “U-Arm Diagram”.)
1. Remove the hexagon socket head plug PT1/8 from the grease
exhaust port.
2. Install a grease zerk A-PT1/8 to the grease inlet. (The grease zerk is
d
elivered with the manipulator.)
3. Inject the grease through the grease inlet using a grease gun
– Grease type: Molywhite RE No. 00
–
Amount of grease: approx. 850 cc
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less
4. The grease exchange is completed when new grease appears in the
g
rease exhaust port. (The new grease can be distinguished from the
old grease by color.)
5. Move the B-Axis for a few minutes t
o discharge excess grease.
6. Wipe the discharged grease with a cloth, a
nd reinstall the plug. Before
installing the plug, apply Three Bond 1206C on the thread part of the
plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
7. Remove the grease zerk from the grease inlet, and reinstall the plug.
Before ins
talling the plug, apply Three Bond 1206C on the thread part
of the plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
NOTE
If grease is injected with the plug on, the grease will leak
inside the motor and may cause a damage. Make sure to
remove the plug before the grease injection.
