发明内容:
本实用新型的目的在于改善现有技术存在的上述技术问题,提供一种结构紧凑,装配定位精确,能有效缩短电机两端轴承室之间的距离,使轴承室中轴承之间的同心度更加精确的塑封电机。
本实用新型是通过以下的技术方案予以实现的。
一种塑封电机,包括塑封定子、转子、转轴和轴承,塑封定子包括定子铁芯、缠绕在定子铁芯上的定子绕组以及包裹在定子铁芯和定子绕组的外围通过树脂制作成型的壳体,转子安装在壳体内部的容腔里面,它还具有至少一个端盖,端盖中央设置有安装轴承的轴承室,轴承支撑着转轴,端盖的外沿处沿轴向凸出有翻边,翻边嵌套在容腔里面与容腔内壁配合实现径向定位,同时使端盖的轴承室部分伸入到容腔里面,端盖的外沿处往外伸出若干个安装脚,塑封定子的外端面设有若干个结合部,安装脚与结合部相配合并安装连接起来。
所述安装脚上开有安装孔,在结合部的位置、塑封定子上开有通孔,外用螺栓穿过安装孔、通孔,用螺母锁紧将端盖安装在塑封定子的外端面上。
上述所述的结合部是凹槽结合部,安装脚嵌入结合部里面,使端盖端面与塑封定子的端面平齐。
该塑封电机具有前端盖和后端盖,通过螺栓、螺母将前端盖和后端盖连接在一起。
该塑封电机的轴承为含油轴承。
本实用新型的有益效果是:电机结构紧凑,端盖与塑封定子之间装配定位精确,特别地,它通过设置在端盖外沿处沿轴向延伸的翻边嵌套在塑封定子的容腔里面与容腔内壁配合实现径向定位,使端盖的轴承室部分延伸到容腔里面,能有效缩短电机两端轴承室之间的距离,使前、后端盖轴承室中的轴承之间的同心度更加精确,定转子的外径同心度得到提高,提高电机产品的一致性、稳定性。
