聯軸器是機械設(she)(she)備(bei)的(de)(de)關鍵構(gou)成構(gou)件(jian)，型(xing)(xing)號(hao)選擇不(bu)善可(ke)(ke)(ke)能危害(hai)機器(qi)設(she)(she)備(bei)運(yun)作(zuo)(zuo)工(gong)作(zuo)(zuo)狀況(kuang)，乃至引起機器(qi)設(she)(she)備(bei)常(chang)見故障。聯軸(zhou)(zhou)器(qi)的(de)(de)型(xing)(xing)號(hao)選擇要依據機器(qi)設(she)(she)備(bei)的(de)(de)工(gong)作(zuo)(zuo)中(zhong)特性、辦公環境等(deng)眾(zhong)多(duo)要素，根據科學研究(jiu)，有效，可(ke)(ke)(ke)用(yong)，經(jing)濟(ji)發(fa)展的(de)(de)標(biao)準，挑選可(ke)(ke)(ke)用(yong)當(dang)場的(de)(de)聯軸(zhou)(zhou)器(qi)，進(jin)而為(wei)機器(qi)設(she)(she)備(bei)運(yun)作(zuo)(zuo)奠定(ding)優(you)良的(de)(de)基本。聯軸(zhou)(zhou)器(qi)因為(wei)構(gou)造和原(yuan)材料不(bu)一樣，用(yong)以每(mei)個機械設(she)(she)備(bei)商品傳(chuan)動裝置的(de)(de)聯軸(zhou)(zhou)器(qi)，其承載力差別非常(chang)大。荷載類(lei)型(xing)(xing)主(zhu)要是對于工(gong)作(zuo)(zuo)中(zhong)機的(de)(de)工(gong)作(zuo)(zuo)中(zhong)荷載的(de)(de)沖擊性、震動、正反轉(zhuan)、制動系統、經(jing)常(chang)起動等(deng)緣故而產生(sheng)不(bu)一樣類(lei)型(xing)(xing)的(de)(de)荷載。為(wei)有利于采(cai)用(yong)測算(suan)，將傳(chuan)動裝置的(de)(de)荷載分成四類(lei)。

聯(lian)軸器不(bu)容易出現輸出聯(lian)軸器健槽友誼鍵損害狀(zhuang)況，機(ji)器設備運(yun)作(zuo)沒有噪音，無震動(dong)，無沖擊性(xing)，各類運(yun)作(zuo)指標值(zhi)(zhi)一切正(zheng)常(chang)，設備故(gu)障率明顯減少。且(qie)該延展(zhan)性(xing)聯(lian)軸器的(de)大(da)(da)轉(zhuan)(zhuan)距值(zhi)(zhi)小于(yu)電機(ji)的(de)顛(dian)復轉(zhuan)(zhuan)距，維(wei)護電機(ji)不(bu)至于(yu)負載，若(ruo)產(chan)生負載乃至"卡住"時，它(ta)可以自(zi)主卸載掉，進而(er)維(wei)護電機(ji)和傳動(dong)機(ji)構(gou)。傳統(tong)(tong)式(shi)系(xi)統(tong)(tong)軟(ruan)件(jian)的(de)荷載類型是挑(tiao)選聯(lian)軸器種(zhong)類的(de)基礎根(gen)據。沖擊性(xing)、震動(dong)和轉(zhuan)(zhuan)知轉(zhuan)(zhuan)變很大(da)(da)的(de)工(gong)作(zuo)中(zhong)荷載，應挑(tiao)選具備隔振器的(de)柔性(xing)聯(lian)軸器即延展(zhan)性(xing)聯(lian)軸器，以緩存、減震、賠償中(zhong)心線(xian)偏位，改進傳動(dong)裝置工(gong)作(zuo)中(zhong)特性(xing)。啟(qi)動(dong)經常(chang)、正(zheng)反轉(zhuan)(zhuan)、制動(dong)系(xi)統(tong)(tong)時的(de)轉(zhuan)(zhuan)距是一切正(zheng)常(chang)穩(wen)定工(gong)作(zuo)中(zhong)時轉(zhuan)(zhuan)距的(de)多(duo)倍。

超重工作中必定減少聯軸器隔振器使用期，聯軸器只容許短時間超重，一般短時間超重不可超出公稱壓力轉距的2~3倍，即≥2~3Tn。低速檔輕載工作狀況應防止采用只適用中小型輸出功率的聯軸器，比如延展性柱銷聯軸器、芯型(xing)延(yan)展(zhan)(zhan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)、多角形硫化橡膠聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)、履帶式聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)等；需操縱過(guo)壓(ya)保護(hu)的(de)軸(zhou)(zhou)系，宜采用聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)；荷載(zai)轉變很大的(de)并有沖擊性(xing)(xing)、震動的(de)軸(zhou)(zhou)系，宜挑選具備隔振器(qi)(qi)(qi)(qi)且緩存和減(jian)震實際效果不(bu)錯的(de)延(yan)展(zhan)(zhan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)。金屬(shu)材(cai)料延(yan)展(zhan)(zhan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)承(cheng)載(zai)力(li)高(gao)過(guo)非(fei)金屬(shu)材(cai)料隔振器(qi)(qi)(qi)(qi)延(yan)展(zhan)(zhan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)；隔振器(qi)(qi)(qi)(qi)受擠壓(ya)成型(xing)的(de)延(yan)展(zhan)(zhan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)可(ke)信性(xing)(xing)高(gao)過(guo)隔振器(qi)(qi)(qi)(qi)受裁切(qie)的(de)延(yan)展(zhan)(zhan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)。
