直流電機(jī)結(jié)構(gòu)復(fù)雜,生產(chǎn)成本高,運(yùn)行維護(hù)較為困難,特別是換向器的使用已逐漸不符合現(xiàn)今低損耗節(jié)能等基本的要求,加之交流電機(jī)的飛速發(fā)展,很多場合交流電機(jī)已得到普及;但由于直流電機(jī)仍具有良好的調(diào)速性能,較大的起動轉(zhuǎn)矩和過載能力等許多優(yōu)點(diǎn),因而在煤礦電力機(jī)械中應(yīng)用仍很廣泛。
而直流電機(jī)的維護(hù)及保養(yǎng)主要集中在電刷、換向器、軸承等元件,同時亦是故障的多發(fā)區(qū)。合理地對其進(jìn)行維護(hù)是正確運(yùn)行直流電機(jī)、迅速排除運(yùn)行故障的關(guān)鍵。
1、 直流電機(jī)的維護(hù)保養(yǎng)
1.1 換向器的維護(hù)保養(yǎng)
換向器是直流電機(jī)中的關(guān)鍵部件,也是觀察直流電機(jī)故障的主要窗口, 直流電機(jī)的故障很多,但常見的也是難處理的是換向故障。換向器工作狀況好壞直接關(guān)系直流電機(jī)的工作狀況,因此必須加強(qiáng)對換向器的維護(hù)保養(yǎng)。

與傳統(tǒng)濕切方式相比，干切方式不需要冷卻液，既環(huán)保又降低了滾齒加工成本，干切方式還可以采用更高的切削速度，提高加工效率。按照干切機(jī)床的加工要求，各主要工具廠家均研發(fā)了環(huán)保干切滾刀，格里森(Gleason)公司、不二越(NACHI)公司、SU公司、漢江工具等，環(huán)保干切滾刀按材料分有整體硬質(zhì)合金滾刀、硬質(zhì)合金可轉(zhuǎn)位滾刀、粉末冶金高速鋼滾刀。整體硬質(zhì)合金滾刀一般用于模數(shù)小于2mm的齒輪，精度可達(dá)AAA級，切削速度可達(dá)25m/min以上；硬質(zhì)合金可轉(zhuǎn)位滾刀一般用于模數(shù)大于6～45mm的齒輪，主要用于磨前粗切，切削速度可達(dá)12～15m/min；粉末冶金高速鋼滾刀一般模數(shù)范圍更寬，可涵蓋所有模數(shù)范圍，這類刀具均采用高性能粉末冶金高速鋼制造，刀具韌性好，加工難度小，其結(jié)構(gòu)特點(diǎn)是小徑加長結(jié)構(gòu)，減少進(jìn)刀出刀時間，并進(jìn)行串刀，提高了刀具耐用度和加工效率，采用粉末冶金材料和高性能涂層，切削速度可達(dá)15～2m/min，精度DINAA級或GBAA級。

減速箱的安裝方法
正確的安裝，使用和維護(hù)減速箱，是保證機(jī)械設(shè)備正常運(yùn)行的重要環(huán)節(jié)。 因此，在您安裝減速箱時，請務(wù)必嚴(yán)格按照下面的安裝使用相關(guān)事項，認(rèn)真地裝配和使用。
步：安裝前確認(rèn)電機(jī)和減速箱是否完好無損，并且嚴(yán)格檢查電機(jī)與減速箱相連接的各部位尺寸是否匹配，這里是電機(jī)的定位凸臺、輸入軸與減速箱凹槽等尺寸及配合公差。
第二步：旋下減速箱法蘭外側(cè)防塵孔上的螺釘，調(diào)整夾緊環(huán)使其側(cè)孔與防塵孔對齊，插入內(nèi)六角旋緊。之后，取走電機(jī)軸鍵。
第三步：將電機(jī)與減速箱自然連接。連接時必須保證減速箱輸出軸與電機(jī)輸入軸同心度一致，且二者外側(cè)法蘭平行。如同心度不一致，會導(dǎo)致電機(jī)軸折斷或減速機(jī)齒輪磨損。
