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(bu)尺寸鏈(lian)，采(cai)(cai)(cai)用(yong)(yong)了大壓力角齒(chi)形設(she)計，軸孔采(cai)(cai)(cai)用(yong)(yong)短(duan)軸設(she)計，縮小了長徑比，結構更加緊(jin)湊，轉速(su)性(xing)能優異。相近(jin)型(xing)號的螺栓(shuan)采(cai)(cai)(cai)用(yong)(yong)標準統(tong)一化，零部(bu)件通用(yong)(yong)性(xing)好。

與國家標準齒式聯軸器相比(bi)能(neng)夠傳(chuan)(chuan)遞更大(da)的(de)扭矩，質量(liang)相對(dui)大(da)幅度減輕(qing)，轉動慣量(liang)小，符合(he)(he)歐洲防(fang)爆要(yao)求，各種綜(zong)合(he)(he)性能(neng)大(da)大(da)超前(qian)。為了(le)更好的(de)傳(chuan)(chuan)動性能(neng)，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較大的扭矩(ju)和(he)允(yun)許較大的角位(wei)移，性能(neng)優(you)異(yi)且(qie)壽命更加長久(jiu)。

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)將不(bu)同(tong)機(ji)構中的主動軸和從(cong)動軸牢(lao)固地聯接起來(lai)一同(tong)旋轉，并(bing)傳遞運(yun)動和扭矩的機(ji)械部件。有時也用以聯接軸與其他(ta)零(ling)件（如(ru)齒輪(lun)(lun)、帶輪(lun)(lun)等(deng)）。

靠背輪常由兩半合成，分別(bie)用鍵或緊配合等聯接(jie)，緊固在兩軸端，再(zai)通過某種方(fang)式將兩半聯接(jie)起(qi)來(lai)。

靠(kao)背輪聯軸(zhou)(zhou)器可兼有(you)補償兩軸(zhou)(zhou)之(zhi)間由于制造(zao)安裝不精確、工(gong)作時的變形或(huo)熱膨脹等原因所發生的偏移（包括軸(zhou)(zhou)向(xiang)偏移、徑向(xiang)偏移、角(jiao)偏移或(huo)綜合偏移）；以及緩和沖擊、吸振(zhen)。

靠背輪為(wei)俗稱，專業叫法(fa)為(wei)聯軸器以及(ji)法(fa)蘭，用于機械設備的連(lian)接。
