4.1.2 Synchronous belt, synchronous belt wheel

Synchronous belt and synchronous belt wheel are the main mechanical parts of the
machine, and they control movement track of the laser head. After movement for a certain
period, the synchronous belt will frequently be longer and loose in a small size. That will lower
the accuracy and sensibility of the laser head; therefore, timely adjusting the transmission belt is
needed.
Adjustment method: Adjustment of X direction and Y direction synchronous belt should
achieve a proper tension of it; adjustment of drive motor synchronous belt is to achieve that
when pressing middle part of the synchronous belt, the sinking level is 3% to 5% of the central
distance between the belt wheels at the two ends.
Attention:
① If to adjust the transmission belt too tight, the belt is not only easily made distortion but
also cause more severe abrasion of the bearing; if too loose, transmission accuracy and
sensibility will be lowered. Therefore, you should adjust the synchronous belt at a proper tension.
While adjust Y direction synchronous belt, it is to achieve a proper ten for the synchronous belt
and make the left and right synchronous belts at the same tension. Only by this way, a stable
transmission synchronous belt can be achieved to ensure a good carving and cutting effect of the
product.
② Keep the synchronous belt away from oil, pr chemicals. Contact with acid, alkali, oil and
organic solvent is prohibited. Keep the synchronous belt dry and clean.
③ There is problem of aging with rubber of the synchronous belt. In case of serous aging (or
abrasion), timely replacing with a new one is required. Please note that synchronous belt wheel
should also be replaced if to replace the synchronous belt.
After using the synchronous belt for a certain period, loose belt and abrasion will also be
caused, and then timely replacement and lockup are needed. Please note that the new
synchronous belt should match with the synchronous belt wheel.
