4.6. Inspection the Timing Belt

 

The timing belt is used for HS165D high density robot in the axis V drive part. If the drive part of timing belt has vibration/noise after every 1500 hours, check the belt tension. In case of inadequate belt tension, it could have a serious bad influence on the performance of robot.

 

n How to check the belt tension

①    Turn the power off.

②    Take off the A2-arm Cover.

③    Figure out the mean by measuring the tension more than 3 times with the sonic tension meter.

④    Compare the computed mean with the adequate belt tension.

⑤    If it does not agree with the adequate tension, loosen the 4-M6X35 bolt of Idle Base, indicated in [Figure 4.4], and adjust the tension by turning the M10X50 of Tension Plate. 

⑥    After adjusting the tension, fasten the 4-M6X35 bolt of Idle Base tight. (adequate tension 400N±10%)

⑦    Lay the A2-Arm Cover.

⑧    Turn the power on.

 

n How to replace the belt

①    Turn the power off.

②    Fix the Axis by inserting the fixing bolt into the pin hole in the Axis V. ( preventing the ARM dropping)

③    Take off the A2-arm Cover.

④    Loosen the 4-M6X35 bolt of Idle Base, indicated in [Figure 4.4], and completely eliminate the belt tension of Tension plate by turning the M10X50 bolt.

⑤    Disassemble the bearing housing connected to the motor axis of Axis V.

⑥    Remove the belt and replace it with a new one.

⑦    Adjust the tension, in the same manner of the above belt tension checkup, and assemble it in the reverse order of disassembly.
