Adjustment Procedures
Results of Improper Adjustment
1) Loosen setscrews
1
and
2
.
2) When turning the main shaft several times, oscillator
3
moves
in the direction of arrow, and it moves naturally to the position
without the load.
3) Temporarily tighten setscrews
1
.
4) Make thrust collar (large)
4
come in contact with face A of the
bed, and tighten setscrew
2
.
1) Loosen setscrews
1
.
2) Closely fitting thrust collar (large)
2
to face A of the bed, turn
it in the direction of arrow to adjust the backlash. Adjust the
backlash so that it is 0.1 mm or less at the tip end of the shuttle
driver, and the shuttle driver smoothly rotates.
3) Tighten setscrews
1
.
(Caution) Be sure to keep the rotating direction shown in the
figure when removing the backlash.
1) Play in the axial direction of the shuttle driver shaft
Loosen two thrust collar setscrews
1
and tighten them while
pressing the shuttle driver shaft in the direction of arrow.
™
If the longitudinal position of the
oscillator is not correct, it will
c a u s e t h e s e i z u r e o f t h e
oscillator or main shaft crank
components.
™
If the backlash is excessive, the
shuttle noise wil be increased.
™
If the backlash is too small, it will
c a u s e t h e s e i z u r e o f t h e
oscillator or main shaft crank
components.
™
When adjusting the backlash, if
the longitudinal position of the
oscillator is not correct, it will
c a u s e t h e s e i z u r e o f t h e
oscillator or main shaft crank
components.
