风力发电系统 - 第4-2部分：风力机传动系统的润滑

[中文适用范围]： IEC TR 61400-4-2:2026 提供了关于风力发电机组齿轮箱润滑剂、润滑系统布局及性能的指导性信息，该信息不具有约束力。本文件涵盖油润滑齿轮箱，并就部分润滑剂参数以及润滑剂特性的监测与维护提供了指导。本文件为风力发电机组传动链的润滑相关事项提供了通用参考标准。ISO/TR 18792 则针对工业齿轮箱的润滑提供了相关信息，其中部分内容与本文件相似或完全一致。本文件适用于风力发电机组系统设计人员、制造单位以及业主/运营方，旨在确保在齿轮箱的设计与运行阶段充分考虑润滑相关事项。本文件聚焦于油润滑齿轮箱，主要基于滚动轴承齿轮箱的应用经验编写。该文件亦可适用于滑动轴承齿轮箱，但尚不能完全涵盖该技术的所有方面。文件结构已预先规划，以便后续纳入风力发电机组传动链中其他部件的相关内容，并扩展纳入其他类型的润滑剂。 [外文原描述]： CORRECTED VERSION 2026-04 IEC TR 61400-4-2:2026 provides non-binding information regarding the lubricant, lubrication system layout, and performance for wind turbine gearboxes. This document covers oil lubricated gearboxes. Additionally, guidance for selected lubricant parameters as well as for monitoring and maintaining lubricant characteristics is offered. This document provides a common reference for lubrication related matters for wind turbine drive trains. ISO/TR 18792 provides information for lubrication of industrial gearboxes. Some information is similar or identical to this document. This document is useful to wind turbine system and component designers, wind turbine manufacturers, and owners/operators to ensure that lubricant related matters are addressed in the gearbox design and operation phases. This current document covers oil lubricated gearboxes and is developed based on experience with predominantly gearboxes with rolling bearings. It can be applied to gearboxes with plain bearings but possibly does not yet address all aspects of this technology. The document structure is prepared to receive further content related to other components in the wind turbine drivetrain and include additional types of lubricants. This corrected version of IEC TR 61400-4-2:2026 incorporates the following correction: - addition in the foreword that this is a double logo technical report prepared in cooperation with ISO/TC 60
