Even more resilient

Mulco is expanding its high-performance timing belt family "move" with a new pitch of 15 millimetres. The endless variant Brecoflex move AT15 is already available. According to the manufacturer, the most important development goal for these versions was to significantly increase belt rigidity.

This is so important because the load capacity of a timing belt drive is not usually limited by the tensile strength of the timing belt, but by its stiffness. The performance limit is reached when the belt pitch becomes so large due to elongation under load that meshing on the pulley no longer runs smoothly. Despite the stronger tension member in the AT15-move timing belts, standard pulleys can still be used. The manufacturer has also FEM-optimized the tooth flank in order to be able to transmit the higher torques cleanly. A laminate on the tooth side reduces friction and makes the timing belt run more smoothly. A smaller minimum diameter with and without counter-bending meets customer requirements for more compact drives.

The Brecoflex-move timing belts are available in widths of 25, 32, 50, 75 and 100 millimetres. In addition to higher transmittable torques, customers benefit from greater positioning accuracy and shorter settling times for dynamic drives. Alternatively, steeper start and stop ramps can also be used. Depending on the application, narrower timing belts and pulleys can be used, which can even reduce costs and installation space. pb
