ContiTech advances rubber timing-belt technology

The Synchroforce Carbon, which is equipped with a hybrid tension member made of a glass carbon compound, is said to match the performance to polyurethane belts.

With the demands on machines growing constantly, there is a constant need for higher-performance belts, according to Rodrigo Maia, head of the Industry EMEA/APAC segment in the ContiTech power transmission group

“One of carbon’s features is that the fibres scarcely stretch even when subjected to a high tensile load,” said Maia.

“When combined with a compound that has been specially designed to cope with high demands, the result is a durable drive solution for challenging applications, for example in machine tools, industrial robots and roller conveyors,” he added.

The new belt transmits rotary motion with great angular precision, while the hybrid tension member help increase tear strength and dynamic load capacity, noted ContiTech.

“This enables synchronous drives to operate in extremely tight spaces – creating the ideal conditions for designing cost-effective drives with a small installed size and low weight,” the company stated.

The Synchroforce Carbon, it continued, is suitable for tropical climates, resistant to ozone and to oil, temperature-resistant from -30°C to +130°C, electrically conductive to ISO 9563 and “very silent”.
