Installation of the Vee belt drive
■ Exactly and carefully align in parallel the axes in all
planes of the driving and the driven shafts.
■ The grooves of the belt pulleys must not be offset.
■
Select the Vee belts according to length to ensure
uniform belt tension.
■ The Vee belt tension is correct when the ready
installed and tensioned belt can be deflected by
the pressure of the thumb by 16 to 20 mm for every
1000 mm axial distance.
Vee belt drive with electric motor is not allowed
because of tilting moment.
