摘　　要：介绍了防爆电机转子装配时,为解决铸铝转子退轴,在转轴上的铁心档与其挡台间设计了因热胀冷缩产生回缩量的间隙。该设计有效地优化了铸铝转子压装的装配工艺,提高了防爆电机装配一次性合格率,确保电机的质量和性能。In order to solve the problem of extracting shaft from casting aluminum rotor, this paper introduces the design of the retracting clearance between iron core and shaft retainer due to thermal expansion and cold shrinkage in the process of rotor assembly of explosion-proof motor. This design scheme has effectively optimized the assembly process of casting aluminum rotor in pressure assembly, improve the one-time pass rate of assembly, and ensure quality and perfomlance of the explosion-proof motor.
