5. Tightening the Timing Belt:
A particularly “stiff” Timing Belt will result in low elongation in operation –
and therefore high positioning accuracy for Linear Units driven by a Timing
Belt.
The pulley/Timing Belt combination is virtually play free.
Belt tension is easily adjusted, all adjustment elements are accessible from
outside.
An M10 tensioning screw with a fine thread is located under the cover of the
Reverse Unit that incorporates the tensioning device.
The tensioning mechanics are designed so that turning clockwise tightens
the belt. Slotted link mechanics.
An adjustment range of 18 mm in the tensioning axle corresponds to an
elongation of 36 mm in the Timing Belt (1 mm tensioning adjustment equals
2 mm elongation in the Timing Belt).
Maximum elongation in the Timing Belt = 36 mm (this yields a maximum
theoretical Timing Belt length of 36 metres with max. 1‰ elongation).
Recommended tensioning method:
Make two marks on the Timing Belt (e.g. 1000 mm apart)
Tension the Timing Belt, 1‰ lengths (maximum elongation!)
Check distance (markings) until they are 1001 mm apart.
6. Extending the carriage with Line 8 Profiles
The preassembled carriage allows you to use the groove of a Line 8 Profile to
design a customised superstructure for the carriage.
For this purpose, two centring sleeves are included with the carriage, which
bring the profile groove into alignment, secure it in place and position the
profile in the desired orientation.
Six individually selectable M8 screws can be used to fasten the profile or a
purpose-made panel to the carriage.
Threads in the carriage: M8x18.
