今天和大(da)家分(fen)享(xiang)的(de)機械小知識是圓臺平(ping)面磨床的(de)零部件—聯軸器

聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)又稱聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)節，是(shi)用(yong)(yong)(yong)來將不(bu)同機(ji)構中的(de)(de)主動(dong)軸(zhou)(zhou)和(he)從動(dong)軸(zhou)(zhou)牢固的(de)(de)連(lian)接起來一(yi)同旋(xuan)轉，并傳遞運動(dong)和(he)扭矩(ju)的(de)(de)機(ji)械部(bu)件，具(ju)有(you)一(yi)定的(de)(de)緩(huan)(huan)沖減震的(de)(de)性能(neng)(neng)，同時具(ju)有(you)過載安全保護的(de)(de)作(zuo)用(yong)(yong)(yong)。在(zai)數(shu)控(kong)磨床(chuang)(chuang)中，一(yi)般選用(yong)(yong)(yong)金屬膜片聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)和(he)梅(mei)花(hua)型(xing)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)，膜片聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)具(ju)有(you)零(ling)回轉間隙，及徑向(xiang)、角向(xiang)和(he)軸(zhou)(zhou)向(xiang)偏差(cha)補償功(gong)能(neng)(neng)。梅(mei)花(hua)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)具(ju)有(you)抗震、緩(huan)(huan)沖和(he)電器(qi)(qi)(qi)(qi)絕(jue)緣功(gong)能(neng)(neng)，適合(he)高轉速和(he)大扭矩(ju)數(shu)控(kong)機(ji)床(chuang)(chuang)，聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)的(de)(de)正確選擇關系(xi)到設備的(de)(de)使用(yong)(yong)(yong)壽命(ming)、噪聲、傳東精度、設備質(zhi)量等一(yi)系(xi)列(lie)問題(ti)。所以選擇時要(yao)考慮到磨床(chuang)(chuang)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)的(de)(de)載荷(he)、許用(yong)(yong)(yong)轉速、工(gong)作(zuo)環(huan)境等綜合(he)因(yin)素(su)。
