Disassembly and Reassembly of T-Axis Speed Reducer
• Refer to Fig. 6-6 "Disassembly & Reassembly of the T-Axis Speed
Reducer".
Disassembly

1. Turn OFF the DX100/DX200/FS100 power supply.
2. Unscrew the GT-SA bolts
the wrist base to the gear
3. Unscrew the hexagon socket head cap screw
gear and the shim

5. Remove the circular spline
6. Remove the wave generator
7. Remove the retaining ring
8. Unscrew the hexagon socket head cap screws
housing and the flex spline

9. Remove old sealing and LOCTITE from each parts.
 Reassembly
1. Put the housing
2. Tighten the hexagon socket head cap screws
torque shown in Table 6-6 "T-Axis Speed Reducer Parts Checklist".
3. Attach the retaining ring
reducer, replace the retaining ring
4. Apply LOCTITE 515 to the matching face between the housing
the circular spline
housing . Also, apply Harmonic Grease SK-1A on the surface

between the teeth of flex spline
5. Press fit the bearings
the housing . (When replace the speed reducer, replace the
11
bearings too.) Also, apply Harmonic Grease SK-1A to the inside
14
wall of the flex spline
diameter of the wave generator
6. Apply LOCTITE 515 to the matching face between the housing
the circular spline
