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(shu)，優化(hua)了很多細部尺寸鏈(lian)，采用(yong)了大壓力角齒(chi)形設(she)(she)計，軸孔采用(yong)短軸設(she)(she)計，縮(suo)小(xiao)了長(chang)徑比，結構更加緊湊，轉速性能優異。相近型號的螺栓采用(yong)標準統一化(hua)，零部件通用(yong)性好。

與國家標準齒式聯軸器相比(bi)能夠傳遞更大的扭(niu)矩，質量相對(dui)大幅度減(jian)輕，轉動慣量小(xiao)，符合歐洲(zhou)防爆要求，各(ge)種綜合性(xing)能大大超前。為了更好(hao)的傳動性(xing)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(de)扭矩和允許較大的(de)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.

靠背輪聯軸器用來(lai)將(jiang)不同(tong)機構(gou)中(zhong)的主動(dong)(dong)軸(zhou)(zhou)和從動(dong)(dong)軸(zhou)(zhou)牢(lao)固地聯接(jie)起(qi)來(lai)一同(tong)旋轉，并(bing)傳(chuan)遞(di)運動(dong)(dong)和扭矩的機械(xie)部(bu)件(jian)。有時也用以聯接(jie)軸(zhou)(zhou)與其他零(ling)件(jian)（如齒輪、帶輪等(deng)）。

靠背輪常由兩半合(he)成，分別用鍵或緊配合(he)等聯接，緊固在兩軸端，再通過某種方式將兩半聯接起來。

靠背輪(lun)聯軸器可(ke)兼有(you)補償(chang)兩軸之間由于制造安裝(zhuang)不精確、工(gong)作時的變形(xing)或(huo)熱膨脹等原因所(suo)發(fa)生的偏移(yi)（包括軸向(xiang)偏移(yi)、徑向(xiang)偏移(yi)、角(jiao)偏移(yi)或(huo)綜合(he)偏移(yi)）；以(yi)及(ji)緩(huan)和沖擊、吸振。

靠背輪為俗稱(cheng)，專業(ye)叫法為聯軸器以及(ji)法蘭(lan)，用于機械設備的(de)連(lian)接。
