Description

用于减速起动机的电枢
技术领域
本实用新型涉及用于内燃机、汽车用减速型起动机，属起动机技术领域，尤其是一种用于减速起动机的电枢。
背景技术
随着汽车工业的发展，小型化、轻量化是社会发展趋势，大力节约能源资源，保护生态环境，建设资源节约型、环境友好型社会的必然选择。一般起动机电枢线采用漆包圆铜线或铜扁线；电枢片齿槽为腰形槽，如要达到较大的电枢力矩或者输出功率增加，必须加大其线径，增大电枢的体积。这样不仅增大了整个电枢的体积，而且造成了资源的浪费。
实用新型内容
为了克服现有的电枢体积大、浪费资源的不足，本实用新型提供了一种用于减速起动机的电枢。
本实用新型解决其技术问题所采用的技术方案是：一种用于减速起动机的电枢，包括电枢轴、电枢片、电枢绝缘片、电枢线和换向器，所述电枢片和电枢绝缘片压在电枢轴内，所述电枢片内插有槽绝缘，所述电枢齿槽内设有电枢线，所述换向器内设有电枢线，所述电枢齿槽为异型槽，上部为圆形，下部为圆扁形，所述电枢线的外层为漆包圆铜线，内层为漆包铜扁线。
根据本实用新型的另一个实施例，进一步包括所述电枢轴采用20CrMnTi材料。
根据本实用新型的另一个实施例，进一步包括电枢片为10钢或者矽钢片。
根据本实用新型的另一个实施例，进一步包括换向器为含银铜材。
本实用新型的有益效果是，本产品外层线为漆包圆铜线，内层线通过压制工艺把漆包圆铜线压成漆包铜扁线；比较相同功率的电枢体积更小，节材；同样体积的电枢力矩更大，输出功率更大。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型的结构示意图；
图2是电枢片的结构示意图；
图3是图2中A部的放大示意图。
图中1、电枢轴，2、电枢片，3、电枢绝缘片，4、电枢线，5、换向器，6、槽绝缘，7、电枢齿槽，8、电枢绝缘线，9、铜铁芯，10、固定环。
具体实施方式
如图1是本实用新型的结构示意图，一种用于减速起动机的电枢，包括电枢轴1、电枢片2、电枢绝缘片3、电枢线4和换向器5，所述电枢片2和电枢绝缘片3压在电枢轴1内，所述电枢片2内插有槽绝缘6，所述电枢齿槽7内设有电枢线4，所述换向器5内设有电枢线4，所述电枢齿槽7为异型槽，上部为圆形，下部为圆扁形，所述电枢线4的外层为漆包圆铜线，内层为漆包铜扁线。
所述电枢轴1采用20CrMnTi材料。电枢片2为10钢或者矽钢片。换向器5为含银铜材。
该电枢由电枢轴1、电枢片2、电枢绝缘片3、电枢线4、槽绝缘6、固定环10、换向器5等组成；把电枢片2、电枢绝缘片3和电枢绝缘线8压入电枢轴1中，在电枢片2内插入槽绝缘6，把成型的电枢线4插入电枢片2的槽内，扭形，压入换向器5，把电枢线4压入换向器5线槽内、焊接，绝缘处理、精加工等完成电枢。
本发明为一种减速起动机电枢，通过起动机通电后使电枢旋转传递转矩，使发动机起动。起动机的工作过程：接通起动机开关，电磁开关通电，在电磁吸力作用下，铜铁芯9被吸动，这时借助拨叉使起动机齿轮前移与发动机飞轮齿环啮合，与此同时，电磁开关主触点闭合，接通起动机电源，电枢旋转传递转矩给发动机曲轴，使发动机起动，停止通电，齿轮退出，起动机停止工作。
通过特殊工艺，使漆包圆铜线做成的电枢线4一半为圆铜线，一半为铜扁线；同时电枢齿槽7为异形槽，上部为圆形，下部为圆扁形，以提高槽满率；本结构使电枢轭部磁通密度更加合理。
