Research on Matching Design Technology of Spherical Roller Main Bearings of Wind Turbine

对用于风力发电机组传动系统的主要轴承类型及其布置型式进行了介绍,对两点支撑式传动链调心滚子主轴轴承的静力学分析、轴承选型计算、轴承内圈与主轴的配合及轴承外圈与轴承座的配合进行了深入研究,提出了调心滚子轴承周边结构件的设计要点及相关计算方法,为风力发电机组传动系统的设计提供参考。

This paper introduced the main bearing types and layout types used in the drivetrain system of wind turbines. In-depth studied of the static analysis of the two-point support drivetrain spherical roller main bearings,the calculation of bearing selection,the tolerance of the bearing inner ring and the main shaft,the tolerance of the bearing outer ring and the bearing housing. This paper put forward the design points and related calculation methods of the peripheral structural parts of spherical roller bearings.It can provide a reference for the design of the wind turbine drivetrain system.
