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.
