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(le)很多細部(bu)(bu)尺寸鏈，采用了(le)大壓力角齒形設計，軸(zhou)孔(kong)采用短軸(zhou)設計，縮小了(le)長徑比，結構更加(jia)緊湊，轉(zhuan)速性(xing)(xing)能優異。相近型號的螺栓采用標準統一(yi)化，零(ling)部(bu)(bu)件(jian)通用性(xing)(xing)好(hao)。

與國家標準齒式聯軸器相比能夠傳遞更大(da)的扭(niu)矩，質量(liang)相對大(da)幅(fu)度減輕，轉動慣量(liang)小(xiao)，符(fu)合歐洲防爆(bao)要求(qiu)，各種綜合性(xing)能大(da)大(da)超前(qian)。為了更好的傳動性(xing)能，我們強烈推薦您(nin)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(chuan)遞較(jiao)大(da)的扭(niu)矩和允許較(jiao)大(da)的角位移(yi)，性能(neng)優(you)異且壽命更(geng)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)來將(jiang)不同機構(gou)中的(de)主動(dong)軸和從動(dong)軸牢固(gu)地聯接起來一同旋(xuan)轉，并傳遞(di)運動(dong)和扭矩的(de)機械(xie)部件(jian)。有時也用(yong)以(yi)聯接軸與(yu)其他(ta)零件(jian)（如齒(chi)輪、帶輪等(deng)）。

靠背輪常由兩半合(he)成(cheng)，分別用(yong)鍵或緊(jin)配合(he)等(deng)聯(lian)接，緊(jin)固在兩軸(zhou)端，再通(tong)過(guo)某種(zhong)方式將(jiang)兩半聯(lian)接起來。

靠背輪聯軸(zhou)器可兼有補償兩(liang)軸(zhou)之間由于制造(zao)安裝不精確、工作時的變形或熱膨(peng)脹等原因所發生的偏(pian)移(yi)（包括軸(zhou)向偏(pian)移(yi)、徑向偏(pian)移(yi)、角偏(pian)移(yi)或綜合偏(pian)移(yi)）；以及緩和沖擊(ji)、吸振。

靠背輪為(wei)俗稱(cheng)，專業叫法(fa)為(wei)聯(lian)軸器以(yi)及法(fa)蘭(lan)，用于機械設備的連接。
