TENSIONING USED PLANETARY BELT
Take the main head of the carriage, like described in
the paragraph “Splitting the carriage from the main
head”, Dismount the top cover.
Noticing speed lost in planetary movement it is possible
to tension the belt for planetary movement as described
in 9.4 Mounting and tensioning a new planetary belt.
9.4 MOUNTING AND TENSIONING A NEW
PLANETARY BELT
Dismount completely the
tensioning device.
Make 2 signs on the
dismounted belt exactly 10
cm out of each other (belt
without tension) (Fig.9.4.1).
The purpose is to measure
10.2 cm on the belt in
tension what is a tension of
2%., a maximum of 2.5% is
allowed.
ATTENTION:
NEVER “OVER”
TENSION THE BELT, THE
BELT WILL BE
DAMAGED AND IT WILL
NEVER RECOVER ITS
ORIGINAL TENSION
Mount the belt back around
the planetary pulley; see
that the belt is behind the
driving pulley (Fig.9.4.2).
Put the belt around the left
roller of the tensioning
device (Fig.9.4.3). Put the
tensioning device back in
place and pull the belt from
the roller on the right side
(Fig.9.4.4). Put the belt
around the driving pulley (Fig.9.4.5). Loose slightly the two bolts of the tensioning device (Fig.9.4.6) (Fig.9.4.7).Begin to
tension until the measure of 10 cm between the marks becomes 10.2 cm (Fig.9.4.9. Tighten the tensioning device while
turning the bolt move the planetary head so the belt can slide. (Fig.9.4.9). Do not forget to lock the tensioning device.
9.5 TENSIONING AND REPLACING THE BELTS
PLEASE MAKE SURE YOU CHECK THE TENSION OF THE BELT AFTER THE FIRST 15 HOURS OF OPERATION
To tension or check the tension of the belts. Open the small bottom cover (Fig. 9.5.1). Check the two belts tension, it is
recommended to
use an
OPTIKRIK II
device (Fig.
9.5.4). The
Static Belt
tension should
be proximally
1150 N, A new
belt 1450 N.
