摘要

摘要: 针对风力机偏航轴承尺寸大, 承载状况复杂, 普通轴承分析方法在此不再适用等问题, 提出一种采用坐标变换原理对各滚球处接触载荷分布进行分析计算的方法。通过在风力机上建立坐标系, 将作用在风机上的外载荷从叶根部位开始传递到偏航轴承的外圈上, 将作用在外圈上的载荷表示为风机各运动参数(风轮旋转、叶片安装角、轴倾角)的函数。在偏航轴承内圈和外圈上各建立一个坐标系, 通过将接触区域的变形表示为两坐标系之间相对运动参数的函数, 建立了整体静力平衡方程。以三种载荷状况为例进行了接触载荷分布求解, 结果表明:倾覆力矩对接触载荷的大小及分布影响最大, 接触载荷基本以正弦规律分布。

Abstract: A method for determining load distribution in yaw bearing of wind turbine using coordinate transformation principle is presented because the analysis procedure for standard bearings can not be used to decide the properties of large scale, complex load conditions of yaw bearing. In order to evaluate the outer loads acting on the yaw bearing, a coordinate system is first established in wind turbine which is used to transmit the loads from the roots of blades to the outer ring of the yaw bearing using coordinate transformation method. Thus the loads acting on the outer ring can be formulated as a function of the motion parameters - such as the rotation of rotor, blade incidence and the angle of rotor shaft - of wind turbine. Then, two coordinates are established on the inner and outer ring, and the static equilibrium equation of yaw bearing is established by expressing the contact elastic deformation as a function of the relative movement parameters of these two coordinates. A calculation example under three load conditions is then presented. The results show that the contact load distribution in the yaw bearing coincides with a sine curve, and the turnover moment has the greatest effect on it.
