摘　　要：根据四级隔爆电机端盖及轴承内盖嵌铜套的结构特点,按铜套与端盖或轴承内盖配合间隙的大小,研究了在满足设计图纸要求及产品性能的前提下,应结合工厂的实际情况选择合适的铜套嵌入工艺。同时介绍了三种铜套嵌入的工艺方法:第一种为热装法;第二种为液氮冷却法;第三种为打顶丝配合法。According to the structural features of end shield and inner cap of 4 poles explosion-proof motor, in terms of the size of the fitting clearance between copper bush and end shield （internal bearing cap）, this article emphases on researching to choose the appropriate copper bush embedding technology combining with real condition of the factory on the premise that the technology meets the requirements of design drawing and product performance. This article introduces three copper bush embeding technological methods： the first is heat assembly method, the second is liquid nitrogen cooling method and the third is bolts fastening method.
