C. Y-shaft timing belt
a) Timing belt at motor operating parts
①
Check timing belt tension of the Y-motor operating
parts by detaching the Y motor base cover from the
body of the machine and using sonic belt
tensiometer.
②
Adjust timing belt tension of the Y-motor operating
parts by flipping with fingers or sticks the middle of the
belt that stretches from the operating pulley
ⓐ
to the
final operating pulley
ⓑ
. Make sure that the measured
value of the sonic belt tensiometer is 30 ~ 31kgf.
③
Input data for the sonic belt tensiometer, when adjusting the
timing belt tension of the Y-main shaft motor operating parts.
Weight: 003.8gf/m
Wide: 40mm/#R
Span: 137mm
④
In order to adjust timing belt tension of the Y-motor
operating parts, unfasten the four idler bracket fixing
screws
ⓒ
. Then pushing the idler
ⓑ
to the left will
increase the tension; while pushing it to the right
will decrease the tension.
b) Y-conveying timing belt
①
Check Y-shaft timing belt tension by moving X-fixing/conveying frame, as in the Figure, to the frontal extreme and
using sonic belt tensiometer.
②
Adjust Y-shaft timing belt tension by flipping with fingers or sticks the middle of the belt that stretches from the end of
the feed bracket to the center
Ⓑ
of the operating pulley. Make sure that the measured value of the sonic belt tensiometer
is 37 ~ 38kgf.
③
Input data for the sonic belt tensiometer, when adjusting Y-shaft timing belt tension.
Weight: 3.8gf/m
Wide: 48mm/#R
Span: 840mm
④
In order to adjust Y-shaft timing belt tension, unfasten the tension base clamp screws
①
and turning tension adjusting
bolt
②
. Turning the tension adjusting bolt
②
clockwise will increase the belt tension; while turning it counter-clockwise
will decrease the tension.
⑤
After adjusting the tension, fasten tension base clamp screw
①
firmly.
