5.9.1 Applying and tensioning of V-belts
For flat belts the proper tension is expressed in %. (The proper tension for this belt
see chapter
„Technical Data“
).
Fig.:
Example of tensioning belt to 2%.

- Lay belt on flat surface and mark outside with two marks in a distance of 1000 mm
(short belts 500 mm).
- Carefully place belt on sheaves and tighten belt with adjusting screws until dis-
tance between marks has grown to indicate proper tension.
For example:
For 2% tension the distance between the marks must be 1020 mm (510 mm)
(see
Fig.).
- Distance of marks to be checked again after rotation drive several times by hand
to distribute belt tension equally.
- Flat belt drives do not have to be re-tensioned; therefore it will be useful to mark
the final position of the motor on the slide rails allowing the belt to be tensioned
very simply after removal for repairs.
The foregoing is only valid for flat belts made by
