•
Move the clamping body to the left-hand end of the cylinder barrel by pulling
on the other end of the toothed belt.
•
Repeat the steps on the other end of the axis to insert the second clamping
body.
•
Push the clamping bodies into the guide in the slide.
Note
Threaded inserts with SCREWLOCK
®
are screwed into the slides. These have
a screw-clamping area that serves as a locking agent. Multiple windings
have a clamping effect on the edges of the screwed-in adjusting screws for
the toothed belt pretension. The result is flexible frictional locking. This
prevents adjustment of the set toothed belt pretension by stopping the
adjusting screw coming loose.
Warning
The clamping effect can damage the thread profile of the adjusting screw,
therefore the use of new adjusting screws is recommended for assembly.
The use of threaded inserts with SCREWLOCK
®
and the dynamic load on
the adjusting screw mean that only original spare parts from Festo with the
appropriate strength class may be used. Otherwise the screws can break
prematurely.
The clamping bodies must not touch the slide when they are being screwed
in as otherwise the toothed belt could become overstretched and the service
life of the toothed belt would be reduced. Slowly increase the toothed belt
pretension to the correct value.
•
Steadily screw the socket head screws through the clamping bodies into the
slide.
•
Pretension the toothed belt by steadily tightening the socket head screws
by feel.
Note
If the toothed belt is cut to the correct length, the clamping bodies should at
least be flush with the slide.
If the clamping bodies protrude, the socket head screws will not reach the
minimum screw-in depth and could be torn out.
Set the toothed belt pretension as described in section
4.1.2 “Checking and
setting the toothed belt pretension”
