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.

卷筒聯軸器是起重設備傳動系統中重要的的部件， 通過其連接減速機動力輸入軸和卷筒契合，傳遞扭矩同時限制卷筒的軸向竄動，并且帶有機械或者電子磨損報警，是卷筒式提升機構的核心部件之一。

卷筒聯軸器是一種新型撓性聯軸器，主要用于起重設備中起升機構的減速器輸出軸與鋼絲繩卷筒的聯接，也適用于其它類似的既傳遞轉矩又承受徑向載荷的機械設備，但不能用作需承受軸向載荷的傳動。

卷筒聯軸器由帶鼓形齒的外齒軸套、帶聯接法蘭和內齒圈的外套、帶外球面的承載環、端蓋和密封圈等組成，并設有定位磨損指針、潤滑油孔和通氣孔等。

外齒軸套和外套構成的鼓形齒式聯軸器傳遞驅動功率, 而由承載環的外球面和外套的內承載面形成的接觸副構成自動調位的球面軸承，承受徑向載荷。聯軸器的內、外齒嚙合在油浴中工作,通過內外端蓋、密封圈防止潤滑脂泄漏。
