Description

一种电机结构
技术领域：
本实用新型涉及一种电机结构。
背景技术：
传统的电机， 包括机壳、 前端盖和后端盖， 前端盖和后端盖安装在机壳两 端， 通过螺栓和螺母配合锁紧， 螺栓尾部凸出螺母， 作为连接外部设备部分， 由于外部设备与螺栓连接的两个通孔中心距通常为 1 1 0mm或者 1 30mm, 对不同 的中心距需要使用不同型号的电机， 使用不同的机壳、 端盖、 定子组件和转子 组件， 物料繁多， 成本增加， 结构复杂。
发明内容：
本实用新型的目的提供一种电机结构， 它结构筒单， 减少物料种类， 降低 生产成本。
本实用新型是通过以下的技术方案予以实现的。
一种电机结构， 包括机壳、 前端盖和后端盖， 前端盖和后端盖安装在机壳 两端， 机壳外壁设有若干支架， 支架上开设通孔， 后端盖边缘凸出若干凸耳， 凸耳上设有安装孔， 安装孔和通孔位置对应， 安装螺釘通过通孔和安装孔并伸 出后端盖端面。
上述所述的在靠近后端盖一端、 支架焊接在机壳的外侧壁面。
上述所述的凸耳和后端盖一体铸铝成型。
上述所述的安装螺釘铆压在支架上。
上述所述的若干支架是 4个， 均布在机壳外侧壁面上。
上述所述的若干凸耳是 4个， 均布在后端盖上。
本实用新型电机拉伸端盖与现有技术相比具有益效果： 1 )本实用新型机 壳外壁设有若干支架， 支架上开设通孔， 后端盖边缘凸出若干凸耳， 凸耳上设 有安装孔， 安装孔和通孔位置对应， 安装螺釘通过通孔和安装孔并伸出后端盖 端面， 结构筒单， 减少物料种类， 降低生产成本； 2 ) 凸耳和后端盖一体铸铝 成型， 在靠近后端盖一端、 支架焊接在机壳的外侧壁面， 由于后端盖是铸铝成 型， 铝的硬度较低， 容易变形， 钢支架起到支承作用， 防止铸铝端盖变形； 3 ) 安装螺釘铆压在支架上， 安装螺釘连接外部设备， 连接紧固。
附图说明：
图 1 是本实用新型电机立体图；
图 2 是本实用新型电机侧视图；
