ROD鼓形齒式聯軸器是Rokee獨立開發的核心技術傳動產品之一并且在國家建立和報備了企業技術標準，結合了日本，德國等先進國家的鼓型齒聯軸器標準技術，優化了很多細部尺寸鏈，采用了大壓力角齒形設計，軸孔采用短軸設計，縮小了長徑比，結構更加緊湊，轉速性能優異。相近型號的螺栓采用標準統一化，零部件通用性好。

與國家標準齒式聯軸器相比能夠傳遞更大的扭矩，質量相對大幅度減輕，轉動慣量小，符合歐洲防爆要求，各種綜合性能大大超前。為了更好的傳動性能，我們強烈推薦您選用。

鼓型齒式聯軸器是一種特別設計的先進齒式聯軸器，其外齒制成球面，球面的中心在齒輪的軸線上，齒側的間隙比一般產品稍大，鼓形齒聯軸器可以傳遞較大的扭矩和允許較大的角位移，性能優異且壽命更加長久。

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.

輪胎聯軸器采用輪胎體狀橡膠元件，與兩個半聯經過螺栓聯接，實現扭矩傳遞和位移補償。橡膠輪胎聯軸器具有較高的彈性性能，扭轉剛度小，減震能力強，軸向補償能力較大，有良好的阻尼性能。

彈性輪胎聯軸器輪胎體是輪胎聯軸器必要的備件之一，相應的分為UL、LA、LB輪胎體。輪胎式聯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。輪胎環內側用硫化方法與鋼質骨架粘接成一體，骨架上的螺栓孔處焊有螺母。裝配時用螺栓與兩半聯軸器的凸緣連接，依靠擰緊螺栓使輪胎與凸緣端面之間產生的摩擦力來傳遞轉矩，輪胎環工作時發生扭轉剪切變形，故輪胎聯軸器具有很高的彈性，補償兩軸相對位移的能力較大，并有良好的阻尼，而且結構簡單、不需潤滑、裝拆和維護都比較方便。

輪胎式聯軸器缺點是承載能力不高、外形尺寸較大，隨著兩軸相對扭轉角的增加使輪胎外形扭歪，軸向尺寸略有減小，將在兩軸上產生較大的附加軸向力，使軸承負載加大而降低壽命。輪胎聯軸器高速運轉時，輪胎外緣由于離心力的作用而向外擴張，將進一步增大附加軸向力。為此，在安裝聯軸器時應采取措施，使輪胎中的應力方向與工作時產生的應力方向相反，以抵消部分附加軸向力，達到改善聯軸器和兩軸承的工和條件。

輪胎式聯軸器由于種種原因使其質心或慣性主軸與其加轉軸線不重合，在運轉時將產生不平衡離心慣性力、離心慣性力偶和動撓度（振型）的現象，稱為轉子的不平衡現象，這種不平衡現象必然引起軸系的振動，從而影響機器的正常工作和使用壽命，因而對其必須加以重視。

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.
