3.5.1.5 Conveyor belt, belt drive and hexagonal shaft
Replacing the toothed belt (conveyor belt)
Parts
Fig.106: Toothed belt (conveyor belt) and movable idler pulleys
1 Input area 03210790-xx Belt L=897mm
2 Inspection area 03121442-xx Synchronous belt L=1506mm
3 Output area 03121441xx Belt L=843mm
4 Movable idler pulleys (see Replacing the idler pulley (conveyor belt))
Equipment and tools
00326015‑xx Belt tension measuring device
00353832-xx Allen key set
Removal
► Use the software or manually move the conveyor rail into a position which allows you best
access.
To move the conveyor side wall manually, pull the toothed belt of the width adjustment unit.
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation.
► Loosen the movable idler pulley.
CAUTION
Loosen the movable idler pulley only as far as necessary!
► Do not remove the movable idler pulley. Otherwise the T slot nut on the inner side will fall into
the conveyor rail.
► Carefully unthread the belt drive.
Installation
► Check the new toothed belt before fitting it. Hold it up high. It should hang loose and should not
twist.
► Follow the removal instructions in reverse order for further installation. Also observe the following
instructions:
●
Do not bend or damage the toothed belt.
●
Make sure that the toothed belt is positioned accurately in the guidance on the motor shaft / belt
drive.
●
When you tighten the idler pulley, set the tension of the toothed belt (see below).

Setting the belt tension
The precalculated values for setting the belt tension can be found in the following chapters.
In addition, the value for any section of the conveyor belt can be calculated using a formula (see Cal-
culating the belt tension).

Overview of measuring points and values
Fig.107: Measuring points
A Movable idler pulleys
1 Measuring point on the toothed belt in the input area 45 +/- 4.5 Hz
2 Measuring point on the toothed belt in the Inspection area 62 +/- 5 Hz
3 Measuring point on the toothed belt in output area 279 +/- 27 Hz
Adjustment
► Use the software or manually move the conveyor rail into a position which allows you best
access.
To move the conveyor side wall manually, pull the toothed belt of the width adjustment unit.
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation.
► Check the belt tension at the relevant measuring point.
► If the belt tension is not correct, adjust the movable idler pulley.
