ROD鼓形齒式聯軸器是Rokee獨立開發(fā)的核心技術傳動產品之一并且在國家建立和報備了企業(yè)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(yōu)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(yōu)異。相近型號的螺栓采用標準統(tǒng)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(yōu)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.

凸緣聯軸器屬于剛性聯軸器，是把兩個帶有凸緣的半聯軸器用普通平鍵分別與兩軸連接，然后用螺栓把兩個半聯軸器連成一體，以傳遞運動和轉矩。這種聯軸器有兩種主要的結構形式：靠鉸制孔用螺栓來實現兩軸對中和靠螺栓桿承受擠壓與剪切來傳遞轉矩；靠一個半聯軸器上的凸肩與另一個半聯軸器上的凹槽相配合而對中。連接兩個半聯軸器的螺栓可以采用A級和B級的普通螺栓，轉矩靠兩個半聯軸器結合面的摩擦力矩來傳遞。凸緣聯軸器結構簡單，制造方便，成本較低，工作可靠，裝拆、維護均較簡便，傳遞轉矩較大，能保證兩軸具有較高的對中精度，一般常用于載荷平穩(wěn)，高速或傳動精度要求較高的軸系傳動。凸緣聯軸器不具備徑向、軸向和角向補償。剛性聯軸器是一種扭轉剛性的聯軸器，即使承受負載時也無任何回轉間隙，即便是有偏差產生負荷時，剛性聯軸器還是剛性傳遞扭矩。
