Axes Speed Reducers (A, B, and C Part)".)
For A and B Part
1. Posture the R- and L-axes as shown in Fig. 9-6(a).
2. Remove the hexagon socket head plugs PT1/8 on the exhaust ports
Ro and Lo and the grease inlets Ri and Li.
If grease is added without removing the hexagon socket
head plugs PT1/8, the internal pressure will increase and
NOTE
may cause a damage.
Never fail to remove the hexagon socket head plugs PT1/8
before the grease injection.
3. Install grease zerks A-PT1/8 on the respective Ri and Li grease inlets,
then inject grease into the respective Ri and Li grease inlets.
Grease Type: Harmonic Grease SK-1A
Amount of Grease: Approx. 4 g
Air Supply Pressure of Grease Pump: 0.3 MPa or less
Use a manual grease gun
4. Move the R- and L-axis for a few minutes to discharge excess grease.
5. Wipe off the exhausted grease with a cloth, and reinstall the hexagon
socket head plugs PT1/8 on the grease inlets Ri and Li and the
exhaust ports Ro and Lo. Apply ThreeBond 1206C to the thread parts.
For C Part
1. Posture the R- and L-axes as shown in Fig. 9-6(a).
2. Remove the hexagon socket head plugs PT1/8 on the grease exhaust
ports Ro and Lo and the grease inlets Ri and Li.
If grease is added without removing the hexagon socket
head plugs PT1/8, the internal pressure will increase and
NOTE
may cause a damage.
Never fail to remove the hexagon socket head plugs PT1/8
before the grease injection.
3. Install grease zerks A-PT1/8 on the respective Ri and Li grease inlets,
then inject grease into the respective Ri and Li grease inlets.
Grease Type: Molywhite RE No.00
Amount of Grease: Approx. 30 g (Approx. 60 g for 1st supply)
Air Supply Pressure of Grease Pump: 0.3 MPa or less
Grease Injection Rate: 8 g or less
4. Move the R- and L-axis for a few minutes to discharge excess grease.
5. Wipe off the exhausted grease with a cloth, and reinstall the hexagon
socket head plugs PT1/8 on the grease inlets Ri and Li and the grease
exhaust ports Ro and Lo. Apply ThreeBond 1206C to the thread parts.
