Why is exact setting of the toothed belt pretension on a toothed belt axis so important?
The toothed belt pretension for a linear axis has a significant influence on its overall performance, particularly on the service life and the skipping behaviour of the belt at maximum load. In general, an excessive pretension not only unnecessarily loads the toothed disc bearings, but also damages the belt, particularly through the high flexural fatigue loads on the cords. On the other hand, if the pretension is too low, this leads to skipping of the toothed belt. The main task of the pretension is therefore to guarantee fault-free meshing of the loose side of the belt, which is almost totally slack with maximum feed forces, with the output disk. The pretension forces for the Festo toothed belt axes are designed in such a way that this operating behaviour is reliably guaranteed even at the maximum feed force.
