大型电机维修拆装时注意事项

1、上瓦面擦(ca)(ca)痕(hen)通常与(yu)轴线没有(you)对准有(you)关，轴瓦两端(duan)止推面擦(ca)(ca)痕(hen)说明磁中(zhong)心与(yu)机械中(zhong)心偏移较大，重新装配(pei)时应(ying)予以调整。

2、打开轴(zhou)承盖翻出轴(zhou)瓦(wa)，彻(che)底清洗轴(zhou)和轴(zhou)瓦(wa)及(ji)各(ge)零部件上(shang)的(de)(de)防(fang)锈脂。用浸(jin)过汽油(you)的(de)(de)无绒(rong)布将其全部擦净(jing)，检(jian)查(cha)轴(zhou)瓦(wa)合(he)金(jin)表面是否有(you)损伤及(ji)嵌入(ru)轴(zhou)瓦(wa)合(he)金(jin)的(de)(de)硬度颗粒(li)。若有(you)损伤或掺入(ru)杂(za)质(zhi)、颗粒(li)，应按进行修复，轴(zhou)承底部的(de)(de)杂(za)质(zhi)应彻(che)底冲洗干(gan)净(jing)。

3、大型电机(ji)轴瓦与轴的(de)间隙在电动机(ji)出厂(chang)时已(yi)选配好(hao)，拆(chai)检时若无损伤不必(bi)再刮修。

4、察看轴瓦表面是(shi)否存在由于轴电流(liu)引起电腐蚀(shi)造成的凹(ao)点。若有此现象，应(ying)检查大(da)型电机轴承绝像是(shi)否完好。

5、大型电机检查轴承内浮动密封圈能否上下移动。若有卡住现象，一般是由于毛刺引起的，修掉即可。否则应重查其尺寸、形状，必要时予以更换。

6、拆检(jian)时(shi)应(ying)仔细察看由轴(zhou)瓦运(yun)行表面(mian)所擦出的(de)(de)光(guang)亮点而形成的(de)(de)痕(hen)迹(ji)，理想的(de)(de)情况应(ying)是(shi)(shi)(shi)：等宽度(du)地沿轴(zhou)向均匀(yun)分(fen)布(bu)在(zai)整个下瓦底部。若擦痕(hen)形成的(de)(de)光(guang)亮点在(zai)宽度(du)上参差(cha)不齐，则可(ke)(ke)能是(shi)(shi)(shi)由于轴(zhou)承装配问题或轴(zhou)的(de)(de)弯曲所致；大型电机轴(zhou)瓦同向刮痕(hen)可(ke)(ke)能是(shi)(shi)(shi)硬质(zhi)颗粒进入轴(zhou)瓦运(yun)行表面(mian)的(de)(de)缘故，或者是(shi)(shi)(shi)因轴(zhou)颈表面(mian)租糙引(yin)起的(de)(de)。拆检(jian)时(shi)应(ying)予修(xiu)复(fu)（清除硬颗粒，用油(you)石打磨轴(zhou)颈的(de)(de)粗糙表面(mian)）或更换。
