In recent years, wind power has become an increasingly important source for clean, renewable energy. As wind turbines have become larger and more powerful, so too have the gearboxes used by the turbines to generate power. Windpower applications also require quiet, rugged, extremely reliable gears manufactured at the highest quality levels, and with methods that continuously drive down cost. As a result, new production methods in gear manufacturing are being employed for gear cutting and finishing operations such as hobbing, shaping and grinding. For gear shaping, for example, a hydraulically powered stroke drive is considered the most robust approach, and ideal for the production of wind power gears. Hydrostatic bearings support stroke lengths of up to 650 mm. An innovative and extremely rigid backoff design supports the shaping forces, cutting speeds, module and stroke length requirements of particularly large gear sizes. In fact, the design is idealyy suited to the high stiffness and rigidity requirments of even the maxumin cutting speed of 50 m/min. Gleason's hydraulically powered shaping heads offer adaptive control, accelerated return strokes and the unique ability to extend cutter life. The achievable gear quality is in the range of DIN class 6 (AGMA class 8).
