胀形间隙对转子屏蔽套胀形量的影响 Fig. 3 Effect of bulging clearance on bulging dimension of rotor can 图4所示为胀形间隙对真空热胀形后转子屏蔽套内径的影响.由图4可以看到,当胀形间隙处于0~0.80 mm范围内时,转子屏蔽套胀形后的内径几乎不随胀形间隙的变化而变化,也就是说,只要经过剪切和焊接制造的转子屏蔽套的胀形间隙处于0~0.80 mm范围内,就可以通过设计的胀形工艺胀到近似相同的尺寸,这也说明真空热胀形工艺具有较高的稳定性. 图4 胀形间隙对胀形后转子屏蔽套内径的影响 Fig. 4 Effect of bulging clearance on internal diameter of rotor can after vacuum hot bulging forming......
