From 15 to 18 September, Winergy will present new options for the maintenance and service of wind turbine gearboxes at the Husum Wind fair. The result: minimizing the risk for the operator and increasing the availability of wind turbines. Until now, when a bearing of the planet carrier in a gearbox needed replacing or servicing it was always necessary to remove the gearbox from the turbine – that included expensive crane work and transport to the manufacturer’s factory. Winergy now has developed a procedure in which the bearing of the planet carrier can be replaced without having to remove the gearbox from the nacelle.
With the aid of specifically designed fixtures it is possible to move the gearbox in the nacelle and thus, the bearing can be removed. The procedure has been successfully tested on the first gearbox on a customer’s turbine and others are to follow. “It cuts the expenses for the operator of the wind turbine and shortens the downtime of the plant. It also contributes to further reducing the cost of generating energy. This is a requirement central to ensuring the economic sustainability of the wind energy of tomorrow”, says Cüneyt Uzkan, head of the Winergy Service.
At the Husum Wind, Winergy will present the new feature in a 3D animation. On a gearbox exhibited on the Winergy stand it is also shown how to replace the intermediate shaft of the cylindrical gear stage on a turbine. The gearbox is opened with a fixture and the service technician can work in the room inside without difficulty to remove the shaft. The replacement procedure on the turbine is significantly shortened, resulting in shorter downtime of the plant.
The gearbox weighs almost 20 tons making it one of the biggest and heaviest exhibits at the fair. These are only two of several maintenance and service operations the Winergy service experts can carry out in the turbine nacelle. “We are the only company providing service and spare parts in original equipment manufacturer quality for our own gearboxes and those of other manufacturers”, Uzkan continues.
Another program by which Winergy increases the availability of wind turbines is its gearbox exchange pool. In the case of a gearbox failure, there are replacements available for all common types. So it is possible to replace the defective gearbox in no time and minimize the downtime of the turbine.
The company offers gearboxes, HybridDrives, couplings, and services to wind turbine manufacturers and wind park operators. The product portfolio covers a power range between 750 kW and 8 MW as well as a special service portfolios. Manufacturing and service locations are in Europe, China, India, and the USA and are continuously expanded worldwide by new service partners.
