Disassembly and Reassembly of R-Axis Speed Reducer
• Refer to
Fig. 6-4 “Disassembly & Reassembly of the R-Axis Speed
.
Disassembly
1. Turn OFF the DX100/DX200/FS100 power supply.
2. Connect the backup batteries with the R-, B- and T-axes motors. After
disconnect all the cables connected to the internal wiring harness, pull
out the internal wiring harness to the S-head side. (Refer to
3. Remove the R-axis motor. (Refer to
Reassembly of the R-Axis Motor”
.)
4. Unscrew the GT-SA bolts
and remove the pipe
. Then remove the
belt
hung on the pulley
. (Refer to
Reassembly of R-Axis Timing Belt”
5. Unscrew the hexagon socket head cap screws
and remove the wrist
unit from the casing. (Refer to
6. Unscrew the GT-SA bolts
and remove the pulley
and the
washer
from the wave generator
.
7. Unscrew the hexagon socket head cap screws
. Then remove the
housing
from the circular spline/ flex spline
with the removal tap
for the housing
.
8. Pull out the wave generator
with the bearings
.
9. Unscrew the hexagon socket head cap screws
and remove the
circular spline/ flex spline
from the U-arm.
10. Remove old sealing from each parts.
Reassembly
1. Apply ThreeBond 1206C to the matching face between the circular
spline/ the flex spline
and the U-arm. Then mount the circular
spline/ the flex spline
on the U-arm.
2. Attach the conical spring washers to the hexagon socket head cap
screws
and apply ThreeBond 1206C to the thread parts. Then
tighten them with the tightening torque shown in
Speed Reducer Parts Checklist”
.
3. Press fit the bearings
into the wave generator
. Apply
ThreeBond 1206C to the joint part of the inside walls of the
bearings
(application amount: about 1 g). (When replace the
speed reducer, replace the bearings
too.)
4. Insert the wave generator
in the circular spline/ the flex spline
.
(Apply Harmonic Grease SK-1A to the bearing of the wave
generator
(application amount: about 2 g).) (When insert the wave
generator
, apply ThreeBond 1206C to the joint part of the outside
wall of the bearing
(application amount: about 1 g).)
5. Apply ThreeBond 1206C to the matching face between the housing
and the circular spline/ the flex spline
. Then mount the housing
on the circular spline/ the flex spline
. (When mount the housing
,
apply ThreeBond 1206C to the joint part of the outside wall of the
bearing
(application amount: about 1 g).)
