Dept. of Mechanical Engineering, Dalian Institute of Science and Technology, Dalian 116052, China; 2. Dalian Jiaotong University, Dalian, 116021,China)Abstract:Using fault tree analysis, the fault tree was established because the Pin Cycloid ary Gear Reducer Used in Propeller Pitch Variator for Wind Turbine can not do its normal work. And fault tree was analyzed through quantitative calculation, the reliability of the gear reducer was analyzed, too. The failure tree analysis discoveredthe reducer’s weak link and the influence onPin Cycloid ary Gear Reducer Used in Propeller Pitch Variator for MW Wind Turbine did not work normally, including its major factors, which provided the basis to improve the system reliable words:Fault tree analys
