4.1.6.2 Calculating the Belt Tension
NOTICE
For conveyor belt only
This calculation only applies to the conveyor belt.
Fig.21: Measuring the distance
► Define the two idler pulleys between which you
want to set the belt tension. If possible, do not
use the movable idler pulleys.
► Measure the distance between the two idler pul-
leys parallel to the conveyor belt. (see dia-
gram)
CAUTION!
Note that it is not always possible to simply
measure the distance between the idler pul-
leys from center to center.
.
► Calculate the belt tension using the following for-
mula:
(20000 / idler pulley spacing [mm]) [Hz]
The permissible tolerance is always plus/minus 10%
of the calculated value.
Example
Distance between the idler pulleys: 235mm
Calculation:
20000 / 235 = 85 (rounded, exactly 85.106…)
10 % of 85.106… = 9 (rounded, exactly 8.5106…)
Result:
Belt tension: 85 +/-9 Hz
