8.2 Belt tension
Standard and checking
Over half the tightening length S = 185 mm the toothed belt 1 must
bend under the test load FV = 50 N so that the loaded belt just touches
the other belt.
Consequences of a too high toothed belt tension
–
Reduced durability
– Noisy running
Consequences of a too low toothed belt tension
–
No faultless mesh between belt teeth and disc toothing
– The teeth may skip over under load
– Non-uniform corner stitches
– Check the belt tension with a spring balance.
Correction
–
Loosen the counternut 3.
– Adjust the belt tension with the eccentric screw 2.
