6.1
Disassembly and Reassembly of S-Axis Speed Reducer
• Refer to
Fig. 6-1 “Disassembly & Reassembly of the S-Axis Speed
Disassembly
1. Turn OFF the DX100/DX200/FS100 power supply.
2. Connect the backup batteries with the S-, L-, U-, R-, B- and T-axes
motors. After disconnect all the cables connected to the internal wiring
harness, remove the internal wiring harness from the manipulator.
(Refer to
.)
3. Remove the S-axis motor. (Refer to
Reassembly of the S-Axis Motor”
4. Unscrew the GT-SA bolts
and remove the M-base
together with
the shaft
.
5. Unscrew the GT-SA bolts
and remove the support B
.
6. Unscrew the hexagon socket head cap screws
and remove the
gear
.
7. Unscrew the hexagon socket head cap screws
. Then detach the
base from the S-head with the removal tap for the base.
8. Remove the bearing
from the M-base.
9. Unscrew the hexagon socket head cap screws
and remove the
circular spline/ the flex spline
from the S-head.
10. Remove the wave generator
from the bearing
and the bearing
and the oil seal
from the S-head as well.
11. Remove old sealing from each parts.
Reassembly
1. Mount the oil seal
on the S-head.
2. Apply ThreeBond 1206C to the matching face between the circular
spline/ the flex spline
and the S-head. Then mount the circular
spline/ the flex spline
on the S-head.
3. Attach the conical spring washers to the hexagon socket head cap
screws
and tighten them with the tightening torque shown in
Table 6-1 “S-Axis Speed Reducer Parts Checklist”
.
4. Press fit the bearing
into the wave generator
. (When replace the
speed reducer, replace the bearings
too.)
5. Apply Harmonic Grease SK-1A to the bearing of the wave
generator
. Then insert the wave generator
in the circular spline/
the flex spline
.
6. Press fit the bearing
into the base. (The bearing
has the sealing
on one side. Turn the sealing side to the gear (the base side) and the
non-sealing side to the S-head.)
7. Mount the collar
on the gear
. Then mount them on the S-base.
8. Apply ThreeBond 1206C to the matching face between the circular
spline/ the flex spline
and the base. Then mount the circular spline/
the flex spline
on the base.
