The reliability of a wind power turbine gearbox is crucial but the safety factors are hard to pre-control quantitatively by the traditional matching method. Therefore, a complete reliability optimisation model of a wind power gearbox transmission is presented. Parameters that affect gear safety factors are classified according to the ISO6336 standard and then the safety factors are expressed as explicit functions, with tooth design parameters as variables. Based on this work, the objective function is established. Common and strength reliability constraints are considered, and Sequential Quadratic Programming (SQP) is applied to the optimisation solution. An example of a gear transmission after reliability optimisation shows that it can better reflect the designer’s expectations and pre-control the level of each safety factor; therefore, this approach can effectively avoid the limitations of the more traditional method.
