(7) Mount the waveform generator to the Joint
#2 motor.
Be sure to fit the end face of the waveform
generator to the end face of the motor shaft.
Tighten one of the setscrews on the flat
face of the motor shaft until the screw just
touches the surface. Insert a bushing into
the other setscrew hole to prevent damage
to the motor shaft. Then, tighten both
setscrews.

CAUTION
■
See the figures above for the orientation of the waveform generator. Be sure to
install the waveform generator properly. Improper installation of the waveform
generator will result in improper function of the Manipulator.
(8) For the prevention of grease leakage, put
an O-ring on the joint area between Arm #1
and the Joint #2 reduction gear unit.
To do so, install an O-ring in the groove of
the clamp face on the Arm #1 side as
shown in the figure on the right.
(9) Mount Arm #1 on the Joint #2 reduction
gear unit.
Loosely fasten all bolts in a crisscross
pattern so that the bolts will be fastened
evenly. Then, using a torque wrench,
tighten each bolt securely in a crisscross
pattern at the proper torque.
