excessively large impact is imposed on Arm, the robot will be damaged.
2.7.6
Mounting Axis 2 Reduction Gear
!
CAUTION
• Handle the reduction gear with extreme care. If it drops or an unusually large external
force is exerted on it, the reduction gear cannot function any further.
• Use the wave generator which is attached to the new reduction gear.
• Also use the “O” ring attached to the new reduction gear. Be sure to set the “O” ring.
Unless the “O” ring is set, grease will leak from the axis 2 reduction gear set surface.
When mounting the reduction gear, take careful precautions not to break the “O” ring.
1)
Mount the wave generator attached to the new reduction gear to the axis 2
motor. At this time, apply grease to the O-ring (CO0538A) and then mount it to
the axis 2 motor flange rabbet. (See
“Para. 2.4.6, Mounting Axis 2 Motor.”)
2)
Cleanly wipe off dusts and stains on the reduction gear of Arm 1.
Apply grease to an O-ring attached to the new reduction gear, and then mount it
in the O-ring groove of Arm 1.
3)
Secure the axis 2 reduction gear to Arm 1 with eight (8) hexagon socket head
cap screws (M3 x 25).
4)
Apply grease to the axis 2 reduction gear. (See
“Para. 2.8.4, Mounting Axis 1
Reduction Ge
ar.”) However, the amount of grease filled is different from that
for the axis 1 reduction gear. Regarding the filled amount for the axis 2
reduction gear, see the following.)
