Product description optibelt OMEGA HL/HP and optibelt OMEGA timing belts Standard properties All Optibelt OMEGA HP timing belts have inherent resistance to oil, heat, cold, ozone and tropical conditions. No special labelling is required Oil resistance The moderate oil resistance prevents the damaging effects of mineral oils and greases, as long as these materials are not in permanent contact with the timing belt and/or are not present in large quantities. With increased demands for resistance, e.g. to mineral or vegetable oils, the performance of the Optibelt OMEGA timing belts can be improved by the use of special constructions. Please contact the Optibelt Applications Engineering Department. Temperature resistance The timing belt can withstand ambient temperatures from ≈ –30 °C to +100 °C. Temperatures outside this range lead to premature ageing and embrittlement of the timing belts and thus to their premature failure. The temperature resistance of Optibelt OMEGA timing belts can be extended by the use of special constructions, e.g. to +140 °C. Please contact the Optibelt Applications Engineering Department. Electrical conductivity (anti static properties) Electrical conductivity enables the safe discharge of electrostatic charges. This charging can have such a strong impact on timing belts with insufficient electrical conductivity that there is the danger of ignition due to sparking. The use of electrically conductive timing belts requires that the properties be checked according to ISO 9563. The electrical conductivity is confirmed by the issue of an inspection certificate. Noise emission The optimised tooth shape and the indent in the tooth tip on the Optibelt OMEGA HP promotes a significantly lower noise level. In combination with the newly developed materials, the noise level is further reduced, even at high speeds and with high belt tensions. Operational life Dynamic tests with Optibelt OMEGA HP show that the running times, compared to standard timing belts, are up to 18 times higher.This results in a considerably higher operational safety of the drive. Efficiency The specially developed tooth fabric and the flexible belt design make possible a virtually frictionless drive with an efficiency of up to 98 %. % 2000 1800 1600 1400 1200 1000 800 600 400 200 0 Operational life Optibelt OMEGA HP Example of application: roller path Standard timing belts 5
Construction 6 Top surface Tension cord Tooth Fabric Top surface The top surface of the OMEGA HL as well as the material of the teeth consists of polychloroprene reinforced with aramid fibre. Thus, an even more abrasion resistant surface is in contact with a reverse bend idler. This surface protects the tension cord from environmental influences. Tension cord In contrast to the OMEGA HP with glass cord, the OMEGA HL uses a considerably stronger, reinforced glass cord. Thus, the power can be further increased by up to 25 %; shock resistance also increases considerably. Teeth Below the tension cord and forming the teeth is a polychloroprene compound reinforced with aramid fibre. This ensures a secure power transfer from the pulley to the tension cord. The considerably increased tooth strength (compared to OMEGA) is made possible by the inclusion use of aramid fibres in the compound. This material enables a very good tooth shape maintenance as well as an increased shear strength for every single tooth of the OMEGA HL. Fabric The shear strength of the teeth is supported by a solid, extremely tough fabric. The shape of the OMEGA teeth and the minimal friction fabric enable a smooth meshing of the belt tooth into the pulley tooth. In addition, the special polyamide fabric is very wear resistant. Product description optibelt OMEGA HL timing belts The new high performance timing belt for extremely high loads across the whole speed spectrum Optibelt has developed this belt in the sections 8M HL and 14M HL especially for drives with high torques and severe shock loads. These types of drives can often be found in general engineering. For this use, the construction and the material of the timing belt have been optimised in such a way that highest operational reliability paired with optimal economic efficiency is reached when newly designing a drive. Initially the belt will be available in the 8M HL section. Optibelt OMEGA, OMEGA HP and OMEGA HL timing belts are used in Optibelt ZRS-HTD ® pulleys or in RPP ® timing pulleys. For applications in other pulleys, please contact the Optibelt Applications Engineering Department. A reinforced glass tension cord is used. This innovative glass cord distinguishes itself by the combination of the following, important characteristics: • good resistance to shock loading • very high dynamic resistance • very low residual and elastic stretch Therefore, the belt performance can be increased by an additional 25 %, compared to OMEGA HP. In contrast to an aramid cord, which also has a very high resistance to shock loading, the reinforced glass cord has a considerably lower residual stretch during the running time. Aramid cord has a high residual stretch (see diagram) during running. The minimal tension loss of the reinforced glass cord leads to the maintenance of the section and thus to a load which is distributed more evenly on the teeth during running. In addition, the reinforced glass cord can also be used at medium and high speeds while the use of the aramid cord is limited to low and medium speeds. In contrast to the aramid cord, the glass cord enables a considerable extension to the range of applications. Belt tension loss Belt tension [N] Time [h]
