With the AT-profile high performance timing belt presented Breco drive technology (Mulco) now belt with 20% higher specific tooth shear strength compared to the previous series. Significantly more compact drives and a higher precision can be achieved in this way. The increase in output was achieved through fine-tuning of many process parameters and the PU material.
Thus, the increased precision of the products lowers the very small but unavoidable relative movement of the toothed belt on the toothed discs and thus the contact temperature. An additional optimized geometric match between the timing belt and toothed pulley leads to a meshing with even less friction, a better stress distribution and thus to a lower peak load on the tooth. The improved quality of the high-strength steel cord tension members and the bifilar winding also have a positive effect on the running properties in the belt drive. The high-performance timing belts are available in endless versions in the form of 'Brecoflex' and, by the meter, endlessly welded as 'Breco'.
