Lessons learned lead to new ideas in gearbox bearings

By Michelle Froese, Senior Editor Windpower Engineering & Development Gearboxes have long taken blame as the typical cause for a wind-turbine failure, and for good reason. Many gearboxes fail to pass the five-year mark without need for component repairs or full replacement. But when the wind industry first got its start, few considered the high

Tips for extending bearing life in wind turbines

Gearbox reliability has improved remarkably in the last 10 years thanks to a better understanding of bearing loads. However, even high-quality components have a limited life expectancy in the wind industry so it is important to have a consistent maintenance plan in place. In this Wind Talk podcast, The Timken Company‘s Rick Brooks discusses new trends

What areas of a wind turbine require bolting and what tools are most useful?

Electric torque wrenches operate on batteries and up to 220 Vac.

What method and tools are used to fasten the bolts on turbines?

The decision whether to use torque or tension to apply a bolt load is determined by the manufacturer of the turbine and the specific pressure needed.
