1. Deflection pulley with slot
2. Measuring point of the belt tension measuring
device (strand center )
X The deflection pulley, around which the
conveyor toothed belt is run, is fastened at a
slot. The tension of the conveyor toothed belt
can be adjusted via this deflection pulley.
X Position the measuring point of the belt
tension device at the strand center (i.e. the
longest distance between the two deflection
pulleys) of the conveyor toothed belt.
X Set the tension of the drive toothed belt
according to the following values.
NOTE:
The tension frequencies per area may vary according to the different belt guides. The belt
tension always remains the same.
