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.

對輪聯軸器慣性主軸線與旋轉軸線之間重心位置偏心量的可能值是平方和方根值而決定的，主要由兩半聯軸器和聯接螺栓組成，對輪聯軸器軸套孔裝配前，鏜削切割和鍵槽的修整聯軸器端面和其它表面的加工等。半聯軸器的軸套孔有圓錐孔和圓柱孔兩種形式，圓錐孔比圓柱孔在工藝特性上有較多的特點，圓錐形軸套孔容易獲得相配合部件之間的同心。

對輪聯軸器在工作過程中，并且會帶來燃油消耗空氣污染等后果，由于承受咬入沖擊動載荷，使得聯軸器受到峰值轉矩，聯軸器承載能力下降，并在短時間內失效，從而直接影響其正常工作，其中的較薄弱環節進行替換或維修是重要和實用的。聯軸器兩軸相對半徑變位要求較好，找耦合同心度為0.2~0.6mm，存在很大困難。如果在駕駛過程中螺栓松動，泵裝置的振動和噪音可能會變大。
