    摘要:

    兆瓦级风电齿轮箱由于运行环境恶劣且载荷工况复杂,齿轮普遍存在微点蚀现象,近年来越来越引起行业内重视。文章以国际微点蚀校核标准ISO/TR15144—1:2010为基础,对影响齿轮微点蚀的齿面粗糙度、变位系数、油温等几个主要因素进行分析,给出合理的推荐值,并开发微点蚀计算软件。结合具体兆瓦级风电齿轮箱设计,提出降低风电齿轮微点蚀风险的具体措施。

    Abstract:

    Gear micropitting phenomenon is common in megawatt-class wind turbine gearbox because of the hard operating environment and complicated load case. More and more attention has been paid to it during recent years. Main factors influencing gear micropitting, such as surface roughness, modification coefficient, oil temperature, are discussed in this paper according to ISO/TR 15144—1:2010. Reasonable values for the factors are suggested and software for calculating micropitting is developed. Based on observation and discussion, measures for reducing gear micropitting risk in wind turbine gearbox design are proposed.
