风力涡轮机 第4部分：风力涡轮机齿轮箱的设计要求

[中文适用范围]： IEC 61400系列的本部分适用于额定功率超过500kW的水平轴风力发电机传动系统的封闭式增速齿轮箱。本标准适用于安装在陆上或海上的风力发电机组。本国际标准为分析与齿轮和齿轮箱元件设计相关的风力涡轮机载荷提供了指导。该标准涵盖的齿轮元件包括正螺旋齿轮或双螺旋齿轮及其在主动力路径中并联和周转布置的组合。本标准不适用于动力输出装置（PTO）。该标准基于使用滚动轴承的齿轮箱设计。本标准允许使用滑动轴承，但不包括它们的使用和额定值。还包括有关轴@轴轮毂接口@轴承和齿轮箱结构的工程指导，以开发满足严格操作条件的完全集成设计。变速箱的润滑以及原型和生产测试都包括在内。最后@提供了齿轮箱的操作和维护指南。 [外文原描述]： IEC 61400-4:2012 is applicable to enclosed speed increasing gearboxes for horizontal axis wind turbine drivetrains with a power rating in excess of 500 kW. This standard applies to wind turbines installed onshore or offshore. It provides guidance on the analysis of the wind turbine loads in relation to the design of the gear and gearbox elements. The gearing elements covered by this standard include such gears as spur, helical or double helical and their combinations in parallel and epicyclic arrangements in the main power path. The standard is based on gearbox designs using rolling element bearings. Also included is guidance on the engineering of shafts, shaft hub interfaces, bearings and the gear case structure in the development of a fully integrated design that meets the rigours of the operating conditions. Lubrication of the transmission is covered along with prototype and production testing. Finally, guidance is provided on the operation and maintenance of the gearbox.
