輪胎聯軸器采用輪(lun)胎(tai)體狀橡膠元件，與兩個半聯經過螺栓聯接(jie)，實現扭矩傳遞和位移補償。橡膠輪(lun)胎(tai)聯軸器具有較(jiao)高的彈性性能(neng)，扭轉(zhuan)剛(gang)度(du)小(xiao)，減震能(neng)力強，軸向補償能(neng)力較(jiao)大，有良(liang)好的阻尼性能(neng)。

彈性輪(lun)胎(tai)聯(lian)軸器(qi)輪(lun)胎(tai)體(ti)是輪(lun)胎(tai)聯(lian)軸器(qi)必要(yao)的(de)備件之一(yi)，相(xiang)應的(de)分為UL、LA、LB輪(lun)胎(tai)體(ti)。輪(lun)胎(tai)式聯(lian)軸器(qi)分為凸型和(he)凹型兩大(da)類，凸型又分為帶骨架整體(ti)式、無骨整體(ti)式和(he)徑向切口式三種。輪(lun)胎(tai)環內(nei)側用硫化方法(fa)與鋼質骨架粘(zhan)接(jie)成一(yi)體(ti)，骨架上的(de)螺(luo)(luo)栓孔處焊有(you)螺(luo)(luo)母。裝配時用螺(luo)(luo)栓與兩半聯(lian)軸器(qi)的(de)凸緣連接(jie)，依(yi)靠擰緊螺(luo)(luo)栓使輪(lun)胎(tai)與凸緣端面(mian)之間產生(sheng)的(de)摩(mo)擦力來傳遞轉矩，輪(lun)胎(tai)環工作時發生(sheng)扭轉剪切變形，故輪(lun)胎(tai)聯(lian)軸器(qi)具有(you)很(hen)高(gao)的(de)彈性，補償兩軸相(xiang)對位(wei)移的(de)能力較大(da)，并(bing)有(you)良好(hao)的(de)阻尼，而且(qie)結構簡(jian)單、不需潤滑、裝拆和(he)維護都比較方便。

輪胎式聯軸器缺點是承載能力(li)(li)不(bu)高、外(wai)形尺寸較大(da)，隨著兩(liang)(liang)(liang)軸(zhou)相對(dui)扭轉角的增(zeng)加使(shi)輪(lun)胎(tai)(tai)(tai)外(wai)形扭歪，軸(zhou)向尺寸略有減小，將在(zai)兩(liang)(liang)(liang)軸(zhou)上產(chan)生較大(da)的附(fu)加軸(zhou)向力(li)(li)，使(shi)軸(zhou)承負載加大(da)而降(jiang)低壽命。輪(lun)胎(tai)(tai)(tai)聯(lian)(lian)(lian)軸(zhou)器高速運轉時，輪(lun)胎(tai)(tai)(tai)外(wai)緣由于離心力(li)(li)的作用(yong)而向外(wai)擴張(zhang)，將進一步增(zeng)大(da)附(fu)加軸(zhou)向力(li)(li)。為此(ci)，在(zai)安裝聯(lian)(lian)(lian)軸(zhou)器時應(ying)采取措施，使(shi)輪(lun)胎(tai)(tai)(tai)中的應(ying)力(li)(li)方(fang)向與工(gong)作時產(chan)生的應(ying)力(li)(li)方(fang)向相反，以抵消部分(fen)附(fu)加軸(zhou)向力(li)(li)，達到改善(shan)聯(lian)(lian)(lian)軸(zhou)器和(he)兩(liang)(liang)(liang)軸(zhou)承的工(gong)和(he)條件。

輪胎式聯軸器由于種(zhong)(zhong)種(zhong)(zhong)原(yuan)因使其(qi)質心(xin)或慣性主軸與其(qi)加轉軸線不重合，在運轉時將產生不平衡(heng)離心(xin)慣性力、離心(xin)慣性力偶(ou)和動撓度(du)（振(zhen)型）的現象(xiang)，稱為轉子的不平衡(heng)現象(xiang)，這種(zhong)(zhong)不平衡(heng)現象(xiang)必然引起(qi)軸系(xi)的振(zhen)動，從而(er)影(ying)響機器的正常(chang)工作和使用(yong)壽命，因而(er)對(dui)其(qi)必須(xu)加以重視(shi)。

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.
