O-ring
(KN4-M257K-000)
Fig. 5-26
13) Fit a new O-ring coated with harmonic grease into the O-ring groove on the
X-axis arm. (See Fig. 5-26.)
14) Place the new harmonic drive on the X-axis arm, and secure it with the
bolts (M3×40L, 8 pieces) you removed earlier. Apply small amounts
of “Screw Lock” to the bolts and tighten them uniformly to secure the
harmonic drive from the backside. (See Fig. 5-25.)
15) 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. 5-27.)
16) Secure the Y-axis arm to the harmonic drive with the bolts (M3×20L, 12
pieces) you removed earlier. Apply small amounts of “Screw Lock” to the
bolts and tighten them uniformly to secure the Y-axis arm. (See Fig. 5-24.)
17) Apply harmonic grease to the new wave generator and flexible spline.
See Fig. 5-27 for applying grease properly.
CAUTION
AN O-RING IS FITTED TO THE UPPER SURFACE OF THE X-AXIS, SO BE
CAREFUL NOT TO LET IT DROP INTO THE PERIPHERAL UNIT. (SEE FIG.
5-26.)
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.
