6. Temporarily tighten the GT-SA bolts .
7. Apply Harmonic Grease SK-1A on the surface between the teeth of
flex spline and the circular spline and insert the circular spline
in the L-arm.
8. Tighten the hexagon socket head cap screws with the tightening
torque shown in Table 6-3 “U-Axis Speed Reducer Parts Checklist”.
9. Apply ThreeBond 1206C to the thread parts of the GT-SA bolts and
tighten them with the tightening torque shown in Table 6-3.
10. Insert the bearings in the wave generator . Then insert it in the
housing . (Apply ThreeBond 1206C to the outside and inside walls of
*a and insert it in the housing and the wave generator .) (When
replace the speed reducer, replace the bearings too.)
11. Tighten the GT-SA bolts with the tightening torque shown in
Table 6-3.
12. Mount the pulley on the wave generator .
13. Attach the conical spring washer and the washer to the hexagon
socket head cap screw and apply LOCTITE 638 to its thread part.
Then tighten it with the tightening torque shown in Table 6-3.
14. Apply ThreeBond 1206C to the matching face between the housing
mounted the wave generator and the circular spline . Then mount
the housing with the circular spline .
15. Put the timing belt on the pulley . (Refer to section 8.1 “Disassembly
and Reassembly of L- and U-Axis Timing Belts”.)
16. Put the internal wiring harness back and mount the cover . (Refer to
Chapter 10 “Cable Wiring”.)
17. Turn ON the DX100/DX200/FS100 power supply.
