A gearbox power loss model, previously validated with experimental results, was used to predict the efficiency of a full wind turbine planetary gearbox. The power loss model account the gears and rolling bearing losses using well established models calibrated with a method proposed by the author. The calculations clearly showed that significant energy savings can be achieved by selecting different base oils, modifying gear tooth geometry, or combining both.<\/jats:p>","DOI":"10.1177\/1350650115622362","type":"journal-article","created":{"date-parts":[[2015,12,17]],"date-time":"2015-12-17T22:05:36Z","timestamp":1450389936000},"page":"983-995","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Power loss prediction: Application to a 2.5\u2009MW wind turbine gearbox"],"prefix":"10.1177","volume":"230","author":[{"given":"Carlos MCG","family":"Fernandes","sequence":"first","affiliation":[{"name":"INEGI, Universidade do Porto, Campus FEUP, Rua Dr. Roberto Frias, Porto, Portugal"}]},{"given":"Maroua","family":"Hammami","sequence":"additional","affiliation":[{"name":"INEGI, Universidade do Porto, Campus FEUP, Rua Dr. Roberto Frias, Porto, Portugal"},{"name":"Laboratory of Mechanical, Modelling and Manufacturing, National School of Engineers of Sfax, University of Sfax, Tunisia"}]},{"given":"Ramiro C","family":"Martins","sequence":"additional","affiliation":[{"name":"INEGI, Universidade do Porto, Campus FEUP, Rua Dr. Roberto Frias, Porto, Portugal"}]},{"given":"Jorge HO","family":"Seabra","sequence":"additional","affiliation":[{"name":"FEUP, Universidade do Porto, Rua Dr. Roberto Frias s\/n, Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2015,12,17]]},"reference":[{"key":"bibr1-1350650115622362","unstructured":"Agency EE.
