6.3.3 Checking the Belt Tension
6.3.4 Checking the Belt Tension for the Vertical Axis
Using a push-pull gauge, push the timing belt for vertical axis with a force of A (gf) and measure the
amount of deflection.
If the deflection is B (mm), the belt tension is normal.
If not, adjust the belt tension by referring to 6.3.6, “Adjusting the Belt Tension for the Vertical Axis.”
Type A B
IX-NNW50 /60 340 ~ 410 (gf) 1.35 (mm)
IX-NNW70 /80 550 ~ 650 (gf) 2.2 (mm)
z When measuring deflection, do not use a gauge with a sharp tip that may damage the belt.
z Disassembling the cover provides opportunities for water and powder dust to enter the robot.
Always disassemble the cover in an appropriate environment where water/powder dust will not
enter the robot.
