• Move the clamping body to the left-hand end of the cylinder barrel.
• Repeat the steps on the other end of the axis to install the second drive
cover.
• Push the clamping bodies into the guide in the slide.
Warning
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.
Note
Set the toothed belt pretension as described in section 4.1.2 “Checking and
setting the toothed belt pretension” .
4.5 Assembly and function check
After completing the assembly work on the toothed belt axis, check the components for correct functioning as follows.
4.5.1 No-load torque
It must be possible to move the slide without much resistance or jerking when idle, without a drive attached or load con-
nected.
This check is based on the technician's instinct and experience. It is not possible to specify precise test values.
