提高采煤机电机定子外配止口加工质量研究

Study on Machining Quality of Motor Stator Rabbet for Shearer

针对采煤机电机定子外配止口加工质量不高的问题,在分析外配止口加工过程的基础上,找出了主要影响因素为机座外配止口尺寸超差,提出了改进措施并得以实施,经抽样样本分析,定子外配止口尺寸超差频次从66.9%降至0。实现了降低次品率和找正工时的目的,为进一步提高采煤机电机定子外配止口加工质量奠定一定的应用基础。

For low quality of motor stator rabbet,find that the main tactors tor rabbet s size tolerance on the basis of analyzing rabbet machining processing. Improvement measures are put forward. These two programs are implemented. Through the sample analysis, rabbet＇s size tolerance frequency tolerance is reduced from 66.9% to 0. The defective rate and working hour of alignment are lowed by these researches. It lay the applied foundation for further improving machining quality of motor stator rabbet for shearer.
