4.5. Checking the timing belt

 

The driving part of all the axes, except for the S axis, has a timing belt.  

For the operating assembly of the timing belt, check the tension of the belt after every 1,500 hours and when there is vibration/noise on the belt. If the tension of the timing belt is not appropriate, it may have a severely negative effect on the performance of the robot.

 

n Check the timing belt

①    Turn off the power.

②    Take off the arm pipe cover.

③    Press the center of the timing belt with the given force (F=0.2kgf).

④    Check the pressed length.

⑤    If the pressed length is not appropriate (3.4mm), loosen the motor flange bolt slightly.

⑥    Set the tension of the timing belt.

⑦    Tighten the motor flange bolt.

⑧    Assemble the arm pipe cover.

⑨    Turn on the power.
