Abstract: A system and method of mounting a wind turbine blade is described, designed to aid in the guiding and alignment of wind turbine blade roots with hub-side components, e.g. a blade pitch system. Furthermore, the system is operable to reduce the effect of blade root ovalization. At least one circular collar is provided which can bear against at least a section of the mounting elements, e.g. blade root bushings, projecting from the root end of a wind turbine blade. The collar acts to absorb the forces pushing the blade root towards an oval shape, thereby providing for improved handling of blade root ovalization and ensuring accurate radial alignment of mounting elements, e.g. stay bolt bores and blade root bushings. Such an improved alignment system reduces the likelihood of bolt failure as a result of component misalignments.

Abstract translation: 描述了安装风力涡轮机叶片的系统和方法，其被设计成有助于风力涡轮机叶片根部与轮毂侧部件的引导和对准，例如。 叶片桨距系统。 此外，该系统可操作以减少叶根根椭圆化的影响。 提供至少一个圆形套环，其可承受至少一部分安装元件，例如， 叶片根部衬套，从风力涡轮机叶片的根部端部突出。 套环用于吸收推动叶片根部朝向椭圆形的力，从而提供改进的叶片根部椭圆形的处理并确保安装元件的精确的径向对准，例如， 保持螺栓孔和叶片根部衬套。 这种改进的对准系统由于部件未对准而降低了螺栓故障的可能性。
