Joint #3 motor

Installation

(1) Mount the pulley and brake hub to the Joint #3

motor.

Insert the brake hub until it touches the end face

of motor shaft and secure the hub.

Be sure to fit the end face of the pulley to the

brake hub.

Tighten one of the set screws on the flat face of

the motor shaft until the screw just touches the

surface.

Insert a bushing into the other set screw hole to prevent damage to the motor shaft.

(2) Mount the Z plate to the Joint #3 motor.

Screw : 4-M4

(3) Pass the Z belt of Joint #3 motor unit through the

ball screw spline.

Place the belt around the pulley.

Make sure that the gear grooves of the belt are fit

into those of the pulleys completely.

(4) Move the Joint #3 motor unit and spline upper

rotator part downwards together and put them on

the Arm #2 upper side.

Be sure to keep the belt on the pulley.

(5) Loosely secure the Joint #3 motor unit to Arm #2.

Check that the motor unit can be moved by hand, and it will not tilt when pulled.
If the unit is secured too loose or too tight, the belt will not have the proper tension.

(6) Place the U1 belt around the pulley.

Place the Joint #4 motor unit on the Arm #2

upper side.
