Toothed Belt Tension - RK Rose+Krieger SQZ-II Montageanleitung

7.5 Toothed belt tension

Before starting any work on the linear unit, any electrical drives used are to be pro-
tected against accidental switching on.
The toothed belt tension is set correctly ex works. A correction is unnecessary in normal opera-
tion.
All toothed belts in linear units need a tension, which is required to guarantee safe engaging of
the teeth even at impact loading and short term overload.
The required pretensioning of the toothed belt must be checked with a pretensioning measu-
rement appliance.
The specific pre-tensioning values for the different types of linear unit are dependent on en-
vironmental parameters, such as the length of the unit, acceleration and loads to be moved and
can be queried with RK Rose+Krieger GmbH for special cases.
Too high a pre-tension will lead to the toothed belt breaking, bearing overload and
reduction of working life.
