Adjustment of V-belts
Adjustment of V-
belt tension
A too tight adjustment of V-belt tension produces heavy wearing on ball bearings thus
reducing useful life of the bearings.
Dantherm
recommends
Dantherm Air Handling A/S recommends using special tools for tightening V-belts in
order to check the values of the table below.
Correct tension of
V-belts
Check the V-belt tension by checking that the deflection (F) is in accordance with the
mm indications of the table below. The deflection strength of each belt is dependent of
the profile type and the distance between the centres.
Use this drawing and the table below to establish the correct belt tension:
