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(biao)準技術，優(you)化了(le)很多細部尺寸鏈，采(cai)用(yong)了(le)大壓力角齒形設(she)計，軸(zhou)(zhou)孔采(cai)用(yong)短軸(zhou)(zhou)設(she)計，縮小了(le)長徑(jing)比，結構更加緊湊，轉速性(xing)能優(you)異。相近型號(hao)的螺栓(shuan)采(cai)用(yong)標(biao)準統(tong)一化，零部件通用(yong)性(xing)好(hao)。

與國家標準齒式聯軸器相(xiang)(xiang)比能夠(gou)傳遞更(geng)大的(de)扭矩，質(zhi)量相(xiang)(xiang)對大幅(fu)度減輕，轉(zhuan)動慣量小，符合歐洲防爆(bao)要求，各種綜合性能大大超前。為了更(geng)好的(de)傳動性能，我們強(qiang)烈推薦您選(xuan)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(di)較大的(de)扭矩和允(yun)許較大的(de)角(jiao)位移，性能(neng)優異且壽(shou)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.

靠背輪聯軸器用(yong)(yong)來(lai)(lai)將不同機(ji)構中的主動軸(zhou)和從動軸(zhou)牢固地聯(lian)接(jie)起來(lai)(lai)一同旋轉，并傳(chuan)遞運動和扭矩的機(ji)械部件。有時也(ye)用(yong)(yong)以聯(lian)接(jie)軸(zhou)與其他零件（如齒輪、帶輪等）。

靠背(bei)輪常由兩(liang)半(ban)合(he)成(cheng)，分別用(yong)鍵或緊配合(he)等聯(lian)接(jie)，緊固在兩(liang)軸端，再通過某(mou)種方式將兩(liang)半(ban)聯(lian)接(jie)起(qi)來。

靠背輪聯軸器可兼(jian)有補償兩(liang)軸之間由(you)于制造安裝不(bu)精確(que)、工作時的變形或(huo)熱膨(peng)脹等原(yuan)因所發生(sheng)的偏移(yi)(yi)（包括軸向偏移(yi)(yi)、徑向偏移(yi)(yi)、角偏移(yi)(yi)或(huo)綜合偏移(yi)(yi)）；以(yi)及(ji)緩和沖擊、吸振。

靠背輪為(wei)俗稱，專業叫法為(wei)聯軸器以(yi)及法蘭(lan)，用于機械設備的(de)連接。
