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.

蛇形彈簧聯軸器是一種結構先進的金屬聯軸器，它靠蛇形彈簧片來傳遞扭矩，蛇形彈簧聯軸器是軸聯接傳動部件，也是一種非常通用的軸聯接傳動部件。蛇簧聯軸器承受扭矩較大，適用于重型機械及通用機械場合。這種經過特殊工藝處的蛇形彈簧，具有很長的使用壽命　允許轉速較高，在軸向、徑向和角向具有良好的補償能力。結構簡單；拆裝方便，使用壽命長；減振效果好，避免了共振。

蛇形聯軸器共有九類型式，分別是JS罩殼徑向安裝型（基本型）、JSB罩殼軸向安裝型、JSS雙法蘭聯接型、JSD單法蘭聯接型、SJS接中間軸型、JSG高速型、JSZ帶制動輪型、JSP帶制動盤型、JSA安全型等。

蛇簧聯軸器其主要結構是由兩個半聯軸節，兩個半外罩，兩個密封圈及蛇形彈簧片組成。它是靠蛇簧嵌入兩半聯軸節的齒槽內來傳遞扭矩，聯軸器以蛇形彈簧片嵌入兩個半聯軸節的齒槽內，來實現主動軸與從動軸的鏈接。蛇型彈簧聯軸器運轉時，是靠主動端齒面對蛇簧的軸向作用力帶動從動端，來傳遞扭矩，如此在很大程度上避免了共振現象發生，且簧片在傳遞扭矩時所產生的彈性變量，使機械系統能獲得較好的減振效果，其平均減振率達36%以上。
