前言随着电力机车车辆性能的提高,电动空气压缩机的性能也得到了提高,特别是电动机由于长期使用而结构方面逐渐陈旧。 C1000、C2000、C3000等各种型号的电动空气压缩机的电枢轴都是不好的。电枢轴的尾端变细,由于经常承受交变重复负荷而经常发生局部断损的情况。滚柱轴承内圈 Preface With the improvement of the performance of electric locomotives and vehicles, the performance of electric air compressors has also been improved. Especially, the structure of the electric motor gradually becomes obsolete due to its long-term use. C1000, C2000, C3000 and other types of electric air compressor armature shaft is not good. The trailing end of the armature shaft is tapered, and partial breakage often occurs due to frequent repeated alternating loads. Roller bearing inner ring
