4.5. Checking the timing belt

 

HH7 has a part where the timing belt is applied to the driving part.

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.

 

Ex)

n  Checking the timing belts of B/R1 axes

①     Turn off the power.

②     Disassemble wrist cover.

③    Press the timing belt with the given force (F = 0.2 kgf) as shown in the figure.

④     Check the pressing amount.

⑤     If it does not match the proper pressing amount (3.4 mm), loosen the motor flange slightly.

⑥     Set the tension of the timing belt.

⑦    Fasten the motor flange bolts tightly. (75kgf·cm)

⑧     Assemble the wrist cover.

⑨     Turn on the power.
