Abstract

本实用新型涉及一种自行车摩电灯发电机的改进,它包括摩擦轮、轴、定子壳、转子、定子、机壳,特点是,轴的两端置于两个由粉末冶金压制的短轴承座上,定子壳和机壳与轴承配合部分分别翻边成与两个短轴承相配合的轴承座,它是由现有的长轴承分制成两个短轴承,经这样的改进,克服了长轴承加工时直线度误差大,使轴与轴承两者的配合间隙大而产生较大的振动和噪声的缺点,使自行车摩电灯发电机在高速运行时,振动和噪声小。

Description

自行车摩电灯发电机
本实用新型涉及一种自行车摩电灯发电机的改进。
现有的自行车摩电灯发电机如图1所示,它包括轴承1、摩擦轮2、轴3、定子壳4、转子5、定子6、机壳7,轴3置于由粉末冶金整体压制的轴承1上,由于轴长,而相配的轴承亦同样的长,长的轴与长的轴承加工时,其直线度误差较大,两者配合困难,则需增大配合间隙,约需0.1mm左右,这样,则使发电机在高速运转时会产生较大的振动和噪声。
本实用新型的目的是为了克服现有技术的缺点,对发电机的长轴承进行改进,提供一种较小的振动和噪声的自行车摩电灯发电机。
本实用新型的技术方案是这样来实现的,包括摩擦轮、轴、定子壳、转子、定子、机壳,特点是,轴的两端置于两个由粉末冶金压制的短轴承座上,定子壳和机壳与轴承配合部分分别翻边成与两个短轴承相配合的轴承座。
由现有的由粉末冶金整体压制的长轴承分制成同样由粉末冶金压制的两个短轴承,经这样的改进,克服了长轴承加工时直线度误差大,使轴与轴承两者的配合间隙大而产生较大的振动和噪声的缺点,经改进后的配合间隙可减小到0.02~0.04mm,这样,使自行车摩电灯发电机在高速运行时,振动和噪声小。
本实用新型实施例结合附图作进一步说明。
图1为现有的自行车摩电灯发电机结构示意图,
图2为本实用新型结构示意图。
由图2所示,自行车摩电灯发电机包括摩擦轮2、轴3、定子壳4、转子5、定子6、机壳7,轴3的两端置于由粉末冶金压制的两个短轴承座8、9上,定子壳4和机壳7与轴承配合部分分别翻边成两个短轴承8、9的轴承座10、11。
