輪胎式與膜片聯軸器對比
RL系列膜片聯軸器是結合歐洲與日本等優質產品基礎之上獨立開發的高品質產品。膜片式聯軸器擁有更小的(de)(de)體(ti)積，更大(da)的(de)(de)同型扭矩和更合理的(de)(de)配比(bi)尺寸(cun)，補償范圍大(da)，質量輕(qing)轉動慣量小螺(luo)栓與膜(mo)片組的(de)(de)孔(kong)(kong)連接部(bu)位采用特殊的(de)(de)彈性墊套設計，極大(da)減小了(le)孔(kong)(kong)緣部(bu)位應力的(de)(de)集(ji)中，杜絕膜(mo)片的(de)(de)撕裂交損，延長使(shi)用壽命(ming)。
膜片彈性聯軸器采用模塊化設計(ji)，裝配簡單，維修(xiu)更換快捷(jie)。性能(neng)遠超國標JM系(xi)列產(chan)品，大量應(ying)用于風機(ji)系(xi)統，汽輪機(ji)組及其(qi)他重(zhong)要(yao)工(gong)業領域。
彈性膜片聯軸器在傳遞扭矩的同時通過彈性膜片的的變形來補償軸向和角向的位移，是一種高性能的金屬彈性撓性聯軸器。彈性聯軸器結(jie)構(gou)緊湊，傳遞扭矩大，使用壽命長，免維護，耐高(gao)(gao)溫，耐酸堿防腐蝕，適用于高(gao)(gao)溫高(gao)(gao)速及有腐蝕工況環境的軸系傳動(dong)。
The steel lamina coupling is an efficient flexible coupling with no back clearance and free from maintenance. Due to its unique structural design, it can achieve the perfect delivery of torque. Meanwhile, it has excellent performances, including large axial and radial compensation ability, low reply feedback force and wide thermal adaptability, etc. With different change design, it can be applied at most power transmission sites.
Rokee's RL series steel laminae coupling is a high-quality product developed independently on basis of combination of advanced products from Europe and Japan, etc. It has smaller size, larger torque of the same model, more reasonable proportioning size, large compensation scope, light weight and small rotational inertia. With modularized design, it’s easy for assembly, maintenance and replacement. Its performance far exceeds the one of JM series diaphragm coupling. It’s widely applied in the fields of fan systems, turboset and other pumps, etc.
輪胎聯軸器采(cai)用輪(lun)胎(tai)體狀橡膠元件，與兩個(ge)半聯經過螺栓聯接，實現扭矩傳遞和位移補償。橡膠輪(lun)胎(tai)聯軸器具有較高的(de)(de)彈(dan)性性能，扭轉剛度小(xiao)，減震能力(li)強，軸向補償能力(li)較大，有良好的(de)(de)阻尼性能。
彈(dan)性輪(lun)(lun)胎(tai)(tai)(tai)聯(lian)軸(zhou)(zhou)(zhou)器輪(lun)(lun)胎(tai)(tai)(tai)體(ti)(ti)是輪(lun)(lun)胎(tai)(tai)(tai)聯(lian)軸(zhou)(zhou)(zhou)器必要的(de)(de)備件(jian)之一(yi)，相應的(de)(de)分為UL、LA、LB輪(lun)(lun)胎(tai)(tai)(tai)體(ti)(ti)。輪(lun)(lun)胎(tai)(tai)(tai)式聯(lian)軸(zhou)(zhou)(zhou)器分為凸(tu)型和(he)(he)凹型兩(liang)(liang)大類，凸(tu)型又分為帶骨架整(zheng)體(ti)(ti)式、無骨整(zheng)體(ti)(ti)式和(he)(he)徑(jing)向切口式三種。輪(lun)(lun)胎(tai)(tai)(tai)環(huan)內側用硫化方法(fa)與(yu)鋼(gang)質骨架粘接成一(yi)體(ti)(ti)，骨架上(shang)的(de)(de)螺栓孔處焊有(you)螺母。裝配時(shi)用螺栓與(yu)兩(liang)(liang)半聯(lian)軸(zhou)(zhou)(zhou)器的(de)(de)凸(tu)緣連接，依靠擰緊螺栓使(shi)輪(lun)(lun)胎(tai)(tai)(tai)與(yu)凸(tu)緣端面之間產生(sheng)的(de)(de)摩擦力(li)來傳遞轉(zhuan)矩(ju)，輪(lun)(lun)胎(tai)(tai)(tai)環(huan)工作時(shi)發生(sheng)扭轉(zhuan)剪切變形，故輪(lun)(lun)胎(tai)(tai)(tai)聯(lian)軸(zhou)(zhou)(zhou)器具有(you)很(hen)高的(de)(de)彈(dan)性，補(bu)償兩(liang)(liang)軸(zhou)(zhou)(zhou)相對位移(yi)的(de)(de)能力(li)較大，并有(you)良(liang)好的(de)(de)阻尼，而且(qie)結構簡單、不(bu)需潤滑、裝拆和(he)(he)維護都比較方便。
輪胎式聯軸器缺點(dian)是承載能力(li)不高、外(wai)(wai)形尺(chi)寸(cun)較大(da)(da)，隨著兩(liang)軸(zhou)相對扭轉角(jiao)的(de)(de)增加使(shi)輪(lun)胎外(wai)(wai)形扭歪，軸(zhou)向(xiang)尺(chi)寸(cun)略有減小，將在兩(liang)軸(zhou)上產(chan)生(sheng)較大(da)(da)的(de)(de)附加軸(zhou)向(xiang)力(li)，使(shi)軸(zhou)承負載加大(da)(da)而(er)降(jiang)低壽命。輪(lun)胎聯軸(zhou)器高速(su)運轉時(shi)，輪(lun)胎外(wai)(wai)緣由(you)于離心力(li)的(de)(de)作用而(er)向(xiang)外(wai)(wai)擴(kuo)張，將進一步增大(da)(da)附加軸(zhou)向(xiang)力(li)。為此，在安裝聯軸(zhou)器時(shi)應采取措施(shi)，使(shi)輪(lun)胎中的(de)(de)應力(li)方(fang)向(xiang)與工(gong)作時(shi)產(chan)生(sheng)的(de)(de)應力(li)方(fang)向(xiang)相反，以抵消(xiao)部分附加軸(zhou)向(xiang)力(li)，達到改善聯軸(zhou)器和(he)兩(liang)軸(zhou)承的(de)(de)工(gong)和(he)條件。
輪胎(tai)式聯軸器由于種種原因(yin)使(shi)(shi)其(qi)質心(xin)或慣(guan)性主軸與其(qi)加(jia)轉軸線不重合，在運轉時將(jiang)產生(sheng)不平衡離(li)心(xin)慣(guan)性力(li)、離(li)心(xin)慣(guan)性力(li)偶(ou)和動撓(nao)度（振型(xing)）的現象(xiang)(xiang)，稱為(wei)轉子的不平衡現象(xiang)(xiang)，這(zhe)種不平衡現象(xiang)(xiang)必然引起軸系的振動，從而影響機(ji)器的正常工作和使(shi)(shi)用壽命，因(yin)而對其(qi)必須加(jia)以(yi)重視。
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.
