Description

水轮发电机磁极固定装置
技术领域
本实用新型涉及一种用于水轮发电机磁极固定装置。 
背景技术
目前,对于额定功率小于250kw,转速低于200r/min的水轮发电机采用的结构是在磁极铁心内钻螺孔,在磁轭上钻通孔然后上螺母,显然这种结构有很多弊端,由于空间太小扳螺母时费时费力。 
发明内容
本实用新型的目的是为了克服以上的不足,提供一种结构简单,加工方便、易于装配的水轮发电机磁极固定装置。 
本实用新型技术的方案是这样的:它包括内六角螺栓、磁极铁芯及磁轭,磁极铁芯和磁轭通过内六角螺栓相连,磁极铁芯的中间穿以芯轴,在磁极铁芯上钻有通孔,其上端设有沉孔。 
本实用新型的优点是:1、结构简单,加工方便;2、易于装配,装配后水轮发电机定子与转子间气隙均匀。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
如图1所示,它包括内六角螺栓1、磁极铁芯2及磁轭3,磁极铁芯2和磁轭3通过内六角螺栓1相连,磁极铁芯2的中间穿以芯轴,在磁极铁芯2上钻有通孔,其上端设有沉孔。
