Description

一种自行车的轮毂发电机 技术领域
本发明涉及一种轮毂发电机，尤其涉及一种自行车的轮毂发电机。
背景技术
现有自行车的轮毂发电机包括轮毂、轮毂轴、永久磁铁、定子铁心、 筒状磁心、线圈骨架、线圈、固定套筒、固定螺母和垫圈；在定子铁心的中心设有可使轮毂轴穿过的铁心孔，从铁心孔向定子铁心的外周缘设有沟孔；在筒状磁心中心设有磁心孔；轮毂套装在轮毂轴上，永久磁铁配置在轮毂的内侧；通过铁心孔在轮毂轴外周设有与永久磁铁的磁极相对应的具有多个极片的两个定子铁心，线圈骨架设置在两个定子铁心中，线圈绕在线圈骨架上；筒状磁心通过磁心孔套在轮毂轴上并在线圈骨架内；固定套筒与固定螺母设置在轮毂轴上并将两定子铁心夹持住；垫圈设置在固定螺母与定子铁心之间；固定套筒和固定螺母分别都是与轮毂轴相螺纹结合；在自行车的轮毂发电机工作时，为防止筒状磁心跟转，在筒状磁心的外圆周面上设有一凹槽，对应凹槽在线圈骨架内周面上设有一凸边，线圈骨架内周面上的凸边卡入筒状磁心外周面上凹槽中；由于凸边卡入凹槽后结合不是很紧密，从而造成筒状磁心、线圈和定子铁心之间的圆心同心度发生偏差，从而造成自行车的轮毂发电机在发电时的输出电压不稳定。
 技术问题
针对上述缺点，本发明的目的在于提供一种既可防止筒状磁心跟转又可防止筒状磁心、线圈和定子铁心之间的圆心同心度发生偏差的自行车的轮毂发电机。
技术解决方案
本发明的技术内容：一种自行车的轮毂发电机，包括轮毂、轮毂轴、永久磁铁、定子铁心、 筒状磁心、线圈骨架、线圈、固定套筒、固定螺母和垫圈；在筒状磁心中心设有磁心孔；在定子铁心的中心设有可使轮毂轴穿过的铁心孔，定子铁心上设有与永久磁铁的磁极相对应的多个极片，轮毂套装在轮毂轴上，永久磁铁配置在轮毂的内侧；两个定子铁心通过铁心孔设在轮毂轴外周；线圈骨架设置在两个定子铁心中，线圈绕在线圈骨架上；筒状磁心通过磁心孔套在轮毂轴上并在线圈骨架内；固定套筒与固定螺母设置在轮毂轴上并将两定子铁心夹持住；垫圈设置在固定螺母与定子铁心之间；固定套筒和固定螺母都是与轮毂轴相螺纹结合；其特征是在垫圈上设有凸块，在筒状磁心一侧面设有一凹孔，紧靠垫圈的一定子铁心上从铁心孔向定子铁心的外周缘设有沟孔；垫圈上的凸块穿过沟孔卡入筒状磁心的凹孔，由此防止筒状磁心跟转。
 有益效果
本发明与现有技术相比所具有的优点是：本发明是通过在筒状磁心的侧面设置凹槽来插入垫圈上的凸块来防止筒状磁心跟转，由此避免了筒状磁心、线圈和定子铁心之间的圆心同心度发生偏差，由此使得自行车的轮毂发电机在发电时的输出电压稳定。
