輪胎聯軸器采用輪(lun)胎體(ti)狀(zhuang)橡膠(jiao)元件，與兩個(ge)半聯(lian)經過螺栓聯(lian)接，實現扭矩傳遞和位移(yi)補償。橡膠(jiao)輪(lun)胎聯(lian)軸器(qi)具有較(jiao)高的彈性(xing)性(xing)能(neng)(neng)(neng)，扭轉剛度小，減(jian)震能(neng)(neng)(neng)力強，軸向(xiang)補償能(neng)(neng)(neng)力較(jiao)大，有良好的阻尼性(xing)能(neng)(neng)(neng)。

彈(dan)性輪(lun)(lun)胎聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)輪(lun)(lun)胎體(ti)是(shi)輪(lun)(lun)胎聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)必要的備(bei)件(jian)之(zhi)(zhi)一，相應的分(fen)為(wei)UL、LA、LB輪(lun)(lun)胎體(ti)。輪(lun)(lun)胎式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)分(fen)為(wei)凸型和(he)凹型兩大(da)類，凸型又分(fen)為(wei)帶骨(gu)(gu)架(jia)(jia)整體(ti)式(shi)、無骨(gu)(gu)整體(ti)式(shi)和(he)徑向(xiang)切口式(shi)三種。輪(lun)(lun)胎環內側用(yong)硫化方法與鋼質骨(gu)(gu)架(jia)(jia)粘接成一體(ti)，骨(gu)(gu)架(jia)(jia)上的螺(luo)栓孔(kong)處焊有(you)螺(luo)母。裝配時用(yong)螺(luo)栓與兩半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)的凸緣(yuan)連接，依靠擰緊螺(luo)栓使輪(lun)(lun)胎與凸緣(yuan)端面之(zhi)(zhi)間產生(sheng)的摩擦力來傳遞(di)轉(zhuan)矩，輪(lun)(lun)胎環工(gong)作時發(fa)生(sheng)扭轉(zhuan)剪切變形(xing)，故輪(lun)(lun)胎聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)具有(you)很高(gao)的彈(dan)性，補(bu)償兩軸(zhou)(zhou)相對(dui)位(wei)移(yi)的能力較大(da)，并有(you)良好的阻尼，而且結構(gou)簡(jian)單(dan)、不需潤滑、裝拆和(he)維護(hu)都比較方便(bian)。

輪胎式聯軸器缺點是承(cheng)載能(neng)力不高、外(wai)形尺寸(cun)較大(da)，隨著兩軸相(xiang)對扭轉角的(de)增(zeng)(zeng)加(jia)(jia)(jia)使輪(lun)(lun)(lun)胎(tai)(tai)外(wai)形扭歪，軸向(xiang)(xiang)尺寸(cun)略有減小，將在兩軸上產(chan)生較大(da)的(de)附(fu)加(jia)(jia)(jia)軸向(xiang)(xiang)力，使軸承(cheng)負載加(jia)(jia)(jia)大(da)而(er)(er)降低壽命。輪(lun)(lun)(lun)胎(tai)(tai)聯軸器高速運轉時，輪(lun)(lun)(lun)胎(tai)(tai)外(wai)緣由于(yu)離心力的(de)作用而(er)(er)向(xiang)(xiang)外(wai)擴張，將進一步(bu)增(zeng)(zeng)大(da)附(fu)加(jia)(jia)(jia)軸向(xiang)(xiang)力。為此，在安裝聯軸器時應采(cai)取措施，使輪(lun)(lun)(lun)胎(tai)(tai)中的(de)應力方向(xiang)(xiang)與(yu)工(gong)作時產(chan)生的(de)應力方向(xiang)(xiang)相(xiang)反，以抵消部分(fen)附(fu)加(jia)(jia)(jia)軸向(xiang)(xiang)力，達(da)到改善聯軸器和(he)兩軸承(cheng)的(de)工(gong)和(he)條件。

輪(lun)胎式(shi)聯軸(zhou)器由于種(zhong)種(zhong)原(yuan)因使(shi)其(qi)質(zhi)心或(huo)慣(guan)(guan)性主軸(zhou)與其(qi)加轉(zhuan)軸(zhou)線不(bu)(bu)重(zhong)合，在運轉(zhuan)時將(jiang)產生不(bu)(bu)平衡(heng)離心慣(guan)(guan)性力(li)、離心慣(guan)(guan)性力(li)偶和動(dong)撓度(du)（振型）的(de)現(xian)象，稱為(wei)轉(zhuan)子的(de)不(bu)(bu)平衡(heng)現(xian)象，這(zhe)種(zhong)不(bu)(bu)平衡(heng)現(xian)象必然引起(qi)軸(zhou)系(xi)的(de)振動(dong)，從而(er)影(ying)響機器的(de)正常工作和使(shi)用壽命(ming)，因而(er)對(dui)其(qi)必須加以重(zhong)視。

The tyre coupling adopts tyre body-shaped rubber elements, which are connected with two semi-couplings through bolts to realize torque transmission and displacement compensation. Tyre coupling has high elastic performance, small torsional rigidity, strong damping capacity, large axial compensation capacity, and good damping performance.
