V-Belts
V-belts are wearing parts that stretch and must be re-tensioned. Regular checks on the
tension force of the V-belts and the condition of the V-belts are necessary in order to
guarantee a long service life of the V-belts.
Checking the tension force of the V-belt
1. Remove the V-belt cover.
2. Measure the distance between the roller centres.
3. Determine the belt sag force F for each belt at 16 mm sag if sag "b" is
equal to 1 m distance between roller centres. Do this by measuring the
distance between roller centres at a right angle to the V-belt.
Force required for 1m distance between roller
centres and 16mm sag
4. Compare determined value with the value in the above table. If the value
lies below the lowest tolerance limit, the V-belt must be re-tensioned. If
the value lies above the highest tolerance limit, the V-belt must be relaxed.
