Abstract

一种小电机转子,属机械装置领域,用于电机制造。由铸铝转子芯、转轴、挡圈组成。转轴与铸铝转子芯连接的部位设置有滚花,转轴通过滚花与铸铝转子芯进行过度配合连接在一起。挡圈卡在挡圈槽内,可起到轴向定位作用。

Description

一种小电机转子
技术领域:一种小电机转子,属机械装置领域,用于电机制造。
背景技术:在电机转子的制造过程中,传统的方法是使用键槽的方式把转子芯和转轴连接在一起,在小电机转子的制造中,由于转子体积小、转轴细,加工键槽比较困难,一般采用胶粘剂粘结或采用热套工艺固定,但这些连接方式都有它的局限性。
发明内容:在电机生产中,电机转子的质量对整个电机的质量起到关键的作用,为提高转子的质量,改进生产工艺,节约加工成本,本实用新型将提供一种新的小电机转子。
一种小电机转子,由铸铝转子芯、转轴、挡圈组成。其特征在于:转轴2与铸铝转子芯1连接的部位设置有滚花4,转轴2通过滚花4与铸铝转子芯1进行过盈配合连接在一起。挡圈3卡在挡圈槽5内,可起到轴向定位作用。
用这种方式连接比用键槽连接和螺母挡圈连接零件少,对转轴的加工量小,同时还能节约原材料。滚花转轴的最大直径为与转子芯的配合段,车削后的外径可略小于铸铝转子芯的内径,经滚花后部份凸起,其外缘直径略大于转子芯的内径,压入后达到过盈配合的目的。因此,在加工前可选择较细的材料。
附图说明:图1是小电机转子结构示意图,图2是转轴示意图,图中:1——铸铝转子芯、2——转轴、3——挡圈、4——转轴滚花、5——挡圈槽。
具体实施方式:一种小电机转子,由铸铝转子芯、转轴、挡圈组成。转轴2与铸铝转子芯1连接的部位设置有滚花4,转轴2通过滚花4与铸铝转子芯1进行过盈配合连接在一起,挡圈3卡在挡圈槽5内。
