Fig. 9-8: R-Axis Speed Reducer Diagram
1. Remove the hexagon socket head cap screw M6 from the exhaust
port.
2. Remove the hexagon socket head cap screw M6 from the grease inlet.
3. Install a grease zerk A-MT6X1 to the grease inlet. (The grease zerk is
delivered with the manipulator.)
4. Inject grease through the grease inlet using a grease gun. (Refer to
Fig. 9-8 “R-Axis Speed Reducer Diagram”
– Grease type:
Harmonic grease 4B No.2
– Amount of grease:
12 cc (24cc for the first supply)
5. Remove the grease zerk from the grease inlet, and reinstall the screw.
Before installing the screw, apply Three Bond 1206C on the thread
part of the screw, then tighten the screw with a tightening torque of
6 N•m (0.6 kgf•m).
6. Reinstall the screw to the exhaust port. Before installing the screw,
apply Three Bond 1206C on the thread part of the screw, then tighten
the screw with a tightening torque of 6 N•m (0.6 kgf•m).
NOTE
For the ceiling-mounted manipulator, the exhaust port and
the grease inlet are inverted.
NOTE
The exhaust port is used for air exhaust, and the grease is
not exhausted from the exhaust port. Do not inject
excessive grease through the grease inlet.
