GUIDELINES
It is recommended to use pulleys with the maximum diameter
allowed by the application in order to maximise the number of
teeth in mesh and increase the belt peripheral speed. For appli-
cations where high positioning precision is required, it might be
useful to use zero backlash pulleys.
In order to guarantee a reliable drive, it is recommended to use
superior quality pulleys
In case of use of clamping plates, they must have the belt profi-
le, be rigid and guarantee a uniform clamping force on all the
surface. It is recommended to have a minimum of 7 teeth in clamp
to guarantee catalogue performances. In case of belts with HPL
cords, the recommended number of teeth in clamp is 12.
Clamping plates
For a trouble free drive, it is recommended that the structure of
application of the timing belt drive, is as rigid as possible.
That will guarantee high work repeatability.
Machine structure
In most cases linear drives may be taken back to one of the two layouts shown, where a specific system of forces acts.
