Safety information
Correctly designed drives (with regard to geometry and power)
with Optibelt OMEGA HL, Optibelt OMEGA HP and Optibelt
OMEGA timing belts ensure a high level of operational safety and
optimum service life.
Experience shows that unsatisfactory service life is often attributable
to errors in installation and maintenance. In order to avoid this,
we suggest that you observe the following recommendations.
● Timing pulleys
The teeth must be conform to the appropriate standards and
should be clean.
● Alignment
Shafts and pulleys should be aligned prior to the assembly.
Maximum deviations of the shaft parallelism:
Belt widths [mm] Shaft misalignment
≤ 25 ± 1°
> 25 ≤ 50 ± 0.5°
> 50 ≤ 100 ± 0.25°
> 100 ± 0.15°
● Timing belt sets
Timing belts which run on a drive in pairs or in sets of several
belts must be ordered in sets in all cases. This is to ensure that
all belts come from the same manufacturing sleeve and have
an identical length.
● Assembly
Prior to the assembly, the centre distance is to be reduced in
such a way that the timing belt may be fitted without force. If this
is not possible, the timing belt must be installed together with
one or both timing pulleys. Installation with the use of force is
NOT permissible at any time as this can damage the high
quality, low stretch tension cord and other components. This
damage is often not visible.
When using taper bushes, the socket screws should be checked
again after 0.5-1 hour running time using a torque wrench.
Starting torques see page 62.
● Belt tension
The belt tension is to be applied in accordance with the
guidelines on page 30. Further checks after installation are not
necessary.
● Tension idlers
Avoid tension idlers. If this is not possible, follow our recommendations
on page 66 of this manual.
● Maintenance
Optibelt OMEGA HL, Optibelt OMEGA HP and Optibelt
OMEGA timing belts are maintenance free, when used under
normal operationing conditions.
