6.5.1 Adjusting the Tension of the Conveyor Toothed Belt
NOTE:
The belt tension is measured at the strand center (i.e. the longest distance between the two
deflection pulleys) .
6-25: Measuring and setting the tension of the conveyor toothed belt
Legend
1. Deflection pulley with slot
2. Measuring point of the belt tension measuring
device (strand center )
X Each conveyor section contains a deflection
pulley (1), that can be moved. The tension of
the conveyor toothed belt can be adjusted by
moving 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.
