CHAPTER 5 Periodic Inspection
14) Fit an O-ring (supplied with the harmonic drive) coated with harmonic
grease into the O-ring groove on the new harmonic drive. (See Fig. 5-40.)
Apply small amounts of "Screw Lock" to the bolts (M5×25L 8 pieces and
M5×35L 8 pieces) and tighten them to secure the harmonic drive from the
backside of the base. (See Fig. 5-39.)
CAUTION
DO NOT ALLOW THE O-RING TO GET CAUGHT OUT OF THE GROOVE
DURING REASSEMBLY. A TROUBLE WILL OCCUR IF THE ROBOT IS
OPERATED WITH THE O-RING LEFT CAUGHT OUT OF THE GROOVE.
15) Apply harmonic grease to the new wave generator and flexible spline.
See Fig. 5-40 for applying grease properly.
16) Fit a new O-ring into the O-ring groove on the X-axis arm and secure it
to the harmonic drive. Then apply small amounts of "Screw Lock" to the
bolts (M5×55L, 8 pieces) you removed earlier and tighten them uniformly
to secure the X-axis arm. (See Fig. 5-37 and Fig. 5-38.)
CAUTION
DO NOT ALLOW THE O-RING TO GET CAUGHT OUT OF THE GROOVE
DURING REASSEMBLY. A TROUBLE WILL OCCUR IF THE ROBOT IS
OPERATED WITH THE O-RING LEFT CAUGHT OUT OF THE GROOVE.
