风力涡轮机.第4部分:齿轮箱的设计和规范

[中文适用范围]： 本标准适用于功率容量为40kW～2MW的风力发电机组齿轮箱。 它适用于所有平行轴、一级行星齿轮箱以及一级行星齿轮箱和平行轴组合封闭式齿轮箱。 本标准的规定是基于具有上述功率容量和配置的风力发电机组的现场经验。 如果对规范进行适当修改以适应更高容量风力涡轮机的特性，本标准的指南可适用于更高容量风力涡轮机。 寿命要求适用于最小设计寿命为 20 年的风力涡轮机。 [外文原描述]： ISO 81400-4:2005 establishes the design and specification of gearboxes for wind turbines with power capacities ranging from 40 kW to 2MW. It is applicable to all such parallel-axis, one-stage epicyclic and combined one-stage epicyclic and parallel shaft enclosed gearboxes. Its provisions are based on field experience with wind turbines having the above power capacities and configurations; its guidelines can be applied to higher capacity wind turbines provided the specifications are appropriately modified to accommodate the characteristics of higher capacity wind turbines. Life requirements apply to wind turbines with a minimum design lifetime of 20 years. The contents of the corrigendum of December 2005 have been included in this copy. This publication is of high relevance for Smart Grid.
