In 2007, NREL initiated the Gearbox Reliability Collaborative (GRC). The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database in a multi-pronged approach to determine why wind turbine gearboxes do not achieve their expected design life. The collaborative of manufacturers, owners, researchers, and consultants focuses on gearbox testing and modeling and the development of a gearbox failure database. Collaborative members also investigate gearbox condition monitoring techniques. Data gained from the GRC will enable designers, developers, and manufacturers to improve gearbox designs and testing standards and create more robust modeling tools. GRC project essentials include the development of two identical, heavily instrumented representative gearbox designs. Knowledge gained from the field and dynamometer tests conducted on these gearboxes builds an understanding of how the selected loads and events translate into bearing and gear response. This report contains the analysis of the first gearbox design.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e National Renewable Energy Laboratory (Nr\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1249132436\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781249132431\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bibliogov\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/20\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 66\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.30lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.69h x 7.44w x 0.14d","brand":"National Renewable Energy Laboratory (Nr","offers":[{"title":"Paperback","offer_id":48449330151679,"sku":"9781249132431","price":17.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_33cf81c2-52e7-48ff-81b8-ef626491b5bb.jpg?v=1777262901","url":"https:\/\/www.whiterainbookhouse.com\/products\/gearbox-reliability-collaborative-gearbox-1-national-renewable-energy-laboratory-nr-9781249132431","provider":"WR Book House","version":"1.0","type":"link"}
