Tools/equipment
Setting gauge, small [03052363-xx] (1)
Setting gauge, large, collision light barriers
[03051814-xx] (2)
Belt tension measuring device [00326015-xx]
with instruction guide
Measurement setup - measuring the feed
axis belt tension
Please note, that the bridge cover has been
removed in this diagram.
X Push the two setting gauges (1) + (2) under
the toothed belt, at a distance of 360 mm.
The large setting gauge (2) is against the
tower cover (6).
The teeth of the toothed belt (3) must lie on the
setting gauge.
X Press the large setting scale downwards with
a suitable object or with your finger, so that the
toothed belt lies on the gauge (5).
X Adjust the belt tension. To do this, gently pull
the toothed belt or tap it with an Allen wrench,
so that it starts swinging and then measure the
value with the belt tension measuring device.
The belt tension must be 85 Hz. +/-5 Hz..
