10.8.1) Specification of drive belt tension adjusters (sound wave belt tension)
1) Model : U-305 Series Sound Wave Belt Tension Gauge – Standard
2) Manufacturer : UNITTA
10.8.2) Y-axis timing belt
– Push the X driver to the driven pulley and check the timing belt on the Y-axis. Use the sound wave tension
gauge.
– Tension on the Y-axis timing belt should measure 14-15kgf on the sound wave gauge when you pluck the
middle of the belt between the end of the X driver and the drive pulley with your finger or with a similar
tool.
– Input data for the sound wave tension measurer:
• Weight : 003.8gf/m
• Width : 015.0mm/#R
• Span: 488mm
– To adjust the Y-axis timing belt tension, unfasten the tension base screw and turn the bolt. Turn clockwise to
increase and counterclockwise to decrease the tension.
