Grease Lubrication
There are many movable joints and parts on the SCARA Robot. The decelerator
and ball screw spline must be periodically serviced and maintained. Because ball
screw spline is exposed in the open environment for long time to easily accumulate
dust or insufficiently lubricate, a user must pay more attention so that the robot can
efficiently operate.
5-3-1
Lubrication of Ball Screw Spline
Ball screw spline is used for the rotation (J3-axis) and linear (J4-axis) motion of
the robot, supported by two sets of nut respectively. The bearing in the nut needs to be
periodically greased with HIWIN (G04), and the external grooves of ball screw spline
must be kept clean. It is recommended ball screw spline be cleaned and maintained
every three months to keep smoothly running.
Please press the Emergency Stop button and disconnect
the power prior to the maintenance. Don’t make any
maintenance when the robot operates, so that can avoid
electric shock or improper operation.
Don’t remove ball screw spline without the authorization
to influence the running accuracy of the robot.
