The new roller belt BRECOroll
Friction as a tribological loss value is unwanted in most technical processes. It leads to a temperature increase and wear and wastes drive power. To minimize this friction when using polyurethane timing belts in material transport systems, BRECO has developed a new product.
BRECOroll is a new development featuring rollers integrated in the teeth of the belt. BRECO has designed this product for applications in material conveying systems. Timing belts used to transport materials are usually very long.
The load run of the belt is almost always supported by a support rail, which guides the belt on its sides and absorbs the weight of the workpieces on the belt and of the belt itself. This generates friction between the belt and the support rail.
Frequently, a significant percentage of the drive power is used to overcome this self-inhibiting behaviour of the system. During this process, the drive is subject to major forces, generates heat and runs at a low degree of efficiency. The increase in the belt temperature lowers its stability – in particular, that of the welded point of the V connection – and reduces the service life of the belt.
Rollers in the belt teeth replace the sliding friction with rolling friction, which is significantly lower. A significant reduction of the drive power is possible and the system’s self-heating behaviour decreases considerably.
The space required for the axis and roller can only be provided by a large belt tooth with a pitch of 20 mm. The T profile is better suited to this application than the AT profile, because the tooth crown of the AT belt makes contact in the pulley while running around it.
The BRECOroll is only available in the T20 division and only in 100 mm width. Please contact our sales partners for more information.
