HANOVER, Germany—Continental A.G.'s belting technology is helping Xinjiang Goldwind Science and Technology catch the wind.
Engineers with ContiTech, a division of Continental, combined the two timing belt technologies to develop a new belting product that allows for the rotor blades of wind turbines to be adjusted without the use of gears or hydraulics. The belts are being made at Continental's site in Dannenberg, Germany, where the company recently invested $2.5 million to help meet Goldwind's demand for 62 miles of belting each year.
The belts are based on Synchrodrive technology. To achieve a connection with the turbine's tension member, galvanized steel cords are integrated into the belt's interior and coated with polyurethane, which furnishes both the teeth and the back of the belt. Polyurethane is particularly abrasion-resistant.
Most notably, Continental said in its release, is the fabric used in the belt production.
"The fabric reduces wear and absorbs noise and also provides a much more stable structure for the timing belt. This enables us to significantly improve the belt's performance yet further," Rolf Marwede, head of Continental's Dannenberg location said in a statement. "The fabric reinforces the teeth and improves run-in behavior, which in turn, boosts efficiency. Ultimately, we have brought together two product groups to develop the ideal solution for Goldwind's application."
