TransDev brings a new BRECO Innovation to Drives & Controls

BRECOFLEXmove Timing Belt

A polyurethane timing belt specially designed for high-performance drives requiring particularly high stiffness.

• Steel cord tension member with increased tensile stiffness of 70 per cent
• 25 per cent lower friction and 30 per cent higher transmittable peripheral force

A newly developed steel cord tension member with slightly larger diameter increases the tensile stiffness by nearly 70 per cent in comparison with the previous version but is still flexible. By enlarging the tension member cross-section it was possible to increase the tensile strength and the permissible tensile forces.

Greater tensile forces lead to higher stress in the root of the tooth and higher surface pressure on the tooth flank. With the aid of finite element topology optimization, the material distribution layout was optimised to achieve a tooth geometry that ensures more uniform distribution of the load acting on the tooth and still fits existing AT profile pulleys. The tooth flank of the BRECOFLEXmove timing belt is additionally protected by a PE laminate that is wear-resistant and ensures lower friction coefficients.

These optimisations have produced a new high-performance timing belt with 25 per cent lower friction and a 30 per cent higher transmittable peripheral force compared with the standard BRECOFLEX AT timing belt. This allows belt drives to be designed that are 30 per cent more compact than the standard version. Depending on the pulley diameter, considerable costs can be saved using the narrower pulleys. BRECOFLEXmove AT10 polyurethane timing belts are available in widths of 25 to 100mm and lengths of 1400 to 30500mm.
