3.5.2.
Dismantling the toothed belt
We recommend to remove the covers at the drive station and the deflection station
before dismantling the toothed belt (
"Remove covers
(see on page 18)).
Unscrew tensioning bracket on both sides of the sliding carriage and remove from
support in the sliding carriage plate.
(Caution! Make sure not to loose the small distance plate of the LCB040! Unless you can no longer set
the original belt tension!)
Push toothed belt sideward out of the clamping bracket.
3.5.3.
Insert new toothed belt
Remove old toothed belt (
Dismantling
(see on page 21)) and mount new belt.
The new toothed belt must have exactly the same length and pitch as the old
toothed belt!
In the case of a long axis it may be helpful to connect the new belt to the old one
(e.g. with tape) in order to insert the new belt while removing the old one.
Insert ends of belt cautiously into both clamping brackets.
On the LCB040, first screw the clamping bracket to the sliding carriage on the
side of the drive station (as the toothed belt of the LCB040 is tensioned on the
other side of the sliding carriage).
On the LCB040, first screw the clamping bracket to the sliding carriage on the
side of the drive station (as the toothed belt of the LCB040 is tensioned on the
other side of the sliding carriage).
Fix the clamping bracket on the opposite side of the sliding carriage (side towards
the deflection station) and place the original small distance distance plates. The
belt has now its originally preset tension.
If you dispose of a
belt tension measuring device
(see on page 22), you may
use this to tension the belt to a value of 220 N.
The belt of a LCB060 must be tensioned to a value of 760 N.
Please use a suitable
RSM belt tension measuring device
(see on page 22)
for measuring and setting this value.
