As the gear type flexible coupling, it can be applied into various general drive sites. Due to the special hook face drum gear design, in the definitive deviation scope, it can effectively avoid the edge stress concentration at tooth meshing, so it has outstanding radial and angular centering capacity. Moreover, it can ensure long service life. ROD series drum gear coupling is one of Rokee’s core technical products. It has compact and reasonable structure, light weight, small hole-position fitting draw ratio, large pressure angle design, accurate centering and excellent speed performance. The bolt design has been standardized in series, the universality of parts is good and its service life far exceeds the one of domestic products.

The gear sleeve at both sides is in the structure of locating ring and uniform parts are used. In addition, the sealing is excellent and easy. Curved-tooth Gear Couplings are applied with larger pressure angle design. The product design is more reasonable and quality is reliable. The gear backlash is reasonable. All ROD series drum type gear couplings are designed in optimization, the structure is more compact and the proportion of hole diameter and length is more coordinated and reliable. Light weight and small rotational inertia. It’s made of high-quality alloy forged steel. It’s very applicable to the sites with anti-explosion requirements. The bolt size of adjacent models is the same and the installation is more convenient. Gear Coupling parts of same model can be exchanged for installation.

輪胎聯(lián)軸器采用輪胎體狀橡膠元件，與兩個(gè)半聯(lián)經(jīng)過螺栓聯(lián)接，實(shí)現(xiàn)扭矩傳遞和位移補(bǔ)償。橡膠輪胎聯(lián)軸器具有較高的彈性性能，扭轉(zhuǎn)剛度小，減震能力強(qiáng)，軸向補(bǔ)償能力較大，有良好的阻尼性能。

彈性輪胎聯(lián)軸器輪胎體是輪胎聯(lián)軸器必要的備件之一，相應(yīng)的分為UL、LA、LB輪胎體。輪胎式聯(lián)軸器分為凸型和凹型兩大類，凸型又分為帶骨架整體式、無骨整體式和徑向切口式三種。輪胎環(huán)內(nèi)側(cè)用硫化方法與鋼質(zhì)骨架粘接成一體，骨架上的螺栓孔處焊有螺母。裝配時(shí)用螺栓與兩半聯(lián)軸器的凸緣連接，依靠擰緊螺栓使輪胎與凸緣端面之間產(chǎn)生的摩擦力來傳遞轉(zhuǎn)矩，輪胎環(huán)工作時(shí)發(fā)生扭轉(zhuǎn)剪切變形，故輪胎聯(lián)軸器具有很高的彈性，補(bǔ)償兩軸相對(duì)位移的能力較大，并有良好的阻尼，而且結(jié)構(gòu)簡(jiǎn)單、不需潤滑、裝拆和維護(hù)都比較方便。

輪胎式聯(lián)軸器缺點(diǎn)是承載能力不高、外形尺寸較大，隨著兩軸相對(duì)扭轉(zhuǎn)角的增加使輪胎外形扭歪，軸向尺寸略有減小，將在兩軸上產(chǎn)生較大的附加軸向力，使軸承負(fù)載加大而降低壽命。輪胎聯(lián)軸器高速運(yùn)轉(zhuǎn)時(shí)，輪胎外緣由于離心力的作用而向外擴(kuò)張，將進(jìn)一步增大附加軸向力。為此，在安裝聯(lián)軸器時(shí)應(yīng)采取措施，使輪胎中的應(yīng)力方向與工作時(shí)產(chǎn)生的應(yīng)力方向相反，以抵消部分附加軸向力，達(dá)到改善聯(lián)軸器和兩軸承的工和條件。

輪胎式聯(lián)軸器由于種種原因使其質(zhì)心或慣性主軸與其加轉(zhuǎn)軸線不重合，在運(yùn)轉(zhuǎn)時(shí)將產(chǎn)生不平衡離心慣性力、離心慣性力偶和動(dòng)撓度（振型）的現(xiàn)象，稱為轉(zhuǎn)子的不平衡現(xiàn)象，這種不平衡現(xiàn)象必然引起軸系的振動(dòng)，從而影響機(jī)器的正常工作和使用壽命，因而對(duì)其必須加以重視。

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.
