ContiTech's heavy-duty timing belt with carbon tension member
ContiTech has developed a new polyurethane heavy-duty timing belt with carbon tension member - the CONTI SYNCHROCHAIN CARBON. A distinguishing feature of carbon is that the fibres barely stretch, even when under high tensile load. In combination with polyurethane, the product has been developed for demanding drives: the belts are highly resistant to wear and they transmit power very reliably, even in the case of high forces.
Since the requirements placed upon machines are constantly on the rise, the belts must also become ever-more efficient. Rolf Marwede, head of the Polyurethane Belt Segment in the ContiTech Power Transmission Group, explains: "CONTI SYNCHROCHAIN CARBON excels with as much as 30 per cent higher performance as compared to belts with aramid tension members. Drive systems can thus be configured more efficiently by using the new belt, since a narrower construction is possible."
The core of CONTI SYNCHROCHAIN CARBON is the new carbon tension member, which stretches only half as much as a tension member made of aramid under the same load. It thus has better pitch precision under high tensile load. This characteristic, combined with the hard polyurethane teeth, reduces the risk of a tooth jumping substantially. A further advantage is that pre-stress loss is minimised thanks to the high stiffness of the cord, thus further boosting the efficiency of the drive. CONTI SYNCHROCHAIN CARBON thus requires very little maintenance, and helps reduce costs for maintenance, repair and belt replacement. Thanks to its high degree of efficiency, smoother belt operation and the elimination of lubrication, CONTI SYNCHROCHAIN CARBON has many benefits compared with a chain drive, and can replace such drives.
The new CONTI SYNCHROCHAIN CARBON can be used across the entire field of machine and plant engineering and is suitable for demanding applications. Samples of the belt are already available for OEMs and it will be available for dealers starting mid-2013.
