摘　　要：箱式电机钢板机座焊接结构较复杂,焊接应力大,精加工后内孔尺寸发生变化,电机装配后运转会引起振动等问题,严重影响电机质量,因此消除焊接残余应力的工作越来越被重视。通过实际产品测试,研究了退火工艺参数变化对残余应力影响,为电机钢板焊接件退火提供参考依据。The box motor with steel-plate frame has the disadvantages of complex welding structure,large welding stress,change of inner hole size after finish machining and vibration caused by running of motor after assembly,etc.These problems can seriously influence quality of motor,therefore elimination of residual welding stress has become more and more important.By testing the actual products,this paper researches the influence of annealing technology parameters change on the residual stress,and it can provide reference on annealing of the welded steel plate of frame.

关 键 词：箱式电机 残余应力 应变释放系数 退火
