Description

风力发电机离心变桨轮毂
技术领域
本发明涉及一种风力发电机,特别是一种离心变桨轮毂的发电机。
背景技术
现有的风力发电机中,其变桨距技术由于输出稳定、抗大风能力强,发电效率高,已经发展成为一个行业,而风力发电机轮毂又是变桨距风力发电机机构的关键部分,很多轮毂在其结构上的设计不是很简易,在应用中对变桨功能存在一定的不足,没有很大的利用风力效果,
发明内容
本发明的目的是为了解决上述技术的不足而提供一种不但简易可靠,而且根据离心力的大小,自动调节桨距角的风力发电机离心变桨轮毂。
为了达到上述目的,本发明所设计的风力发电机离心变桨轮毂,它主要包括轮毂体、风叶连接轴,在轮毂体中心设置电机轴,在轮毂体上环形均布风叶连接轴,风叶连接轴的中心线与轮毂体中心为圆心的圆相切,风叶连接轴的一端是通过深沟球轴承和圆螺母连接在轮毂体上,可以自由旋转,这样离心力与旋转方向基本保持在一致的方向上,使离心力对旋转作用更明显,深沟球轴承是由压盖固定,风叶连接轴的另一端是风叶固定端,在风叶固定端的背面固定离心锤,所述的离心锤的形状为“7”字型,其中“7”字形的一边与风叶固定端的背面通过螺栓固定,在正常运作中,离心锤使风叶与迎风面调整到最佳状态,变桨效果明显,稳定性好,同时在轮毂体上设置轮毂罩,以保护轮毂体内部结构。
本发明所得到的风力发电机离心变桨轮毂,主体结构设计合理,稳定性好,变桨效果明显,风叶可以自由旋转,使离心力与旋转方向保持在一致的方向,使离心力对旋转作用更加明显,通过风力发电机自身旋转时,离心锤所产生的离心力来控制风叶的迎风角度,最大利用了风力,使得中小型变桨距风力发电机实现变桨功能。
