鼓型齒式聯(lián)軸器是一種特別設(shè)計(jì)的先進(jìn)齒式聯(lián)軸器，其外齒制成球面，球面的中心在齒輪的軸線上，齒側(cè)的間隙比一般產(chǎn)品稍大，鼓形齒聯(lián)軸器可以傳遞較大的扭矩和允許較大的角位移，性能優(yōu)異且壽命更加長(zhǎng)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(lián)軸器用來將不同機(jī)構(gòu)中的主動(dòng)軸和從動(dòng)軸牢固地聯(lián)接起來一同旋轉(zhuǎn)，并傳遞運(yùn)動(dòng)和扭矩的機(jī)械部件。有時(shí)也用以聯(lián)接軸與其他零件（如齒輪、帶輪等）。

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

靠背輪聯(lián)軸器可兼有補(bǔ)償兩軸之間由于制造安裝不精確、工作時(shí)的變形或熱膨脹等原因所發(fā)生的偏移（包括軸向偏移、徑向偏移、角偏移或綜合偏移）；以及緩和沖擊、吸振。

靠背輪為俗稱，專業(yè)叫法為聯(lián)軸器以及法蘭，用于機(jī)械設(shè)備的連接。

凸緣聯(lián)軸器屬于剛性聯(lián)軸器，是把兩個(gè)帶有凸緣的半聯(lián)軸器用普通平鍵分別與兩軸連接，然后用螺栓把兩個(gè)半聯(lián)軸器連成一體，以傳遞運(yùn)動(dòng)和轉(zhuǎn)矩。這種聯(lián)軸器有兩種主要的結(jié)構(gòu)形式：靠鉸制孔用螺栓來實(shí)現(xiàn)兩軸對(duì)中和靠螺栓桿承受擠壓與剪切來傳遞轉(zhuǎn)矩；靠一個(gè)半聯(lián)軸器上的凸肩與另一個(gè)半聯(lián)軸器上的凹槽相配合而對(duì)中。連接兩個(gè)半聯(lián)軸器的螺栓可以采用A級(jí)和B級(jí)的普通螺栓，轉(zhuǎn)矩靠?jī)蓚€(gè)半聯(lián)軸器結(jié)合面的摩擦力矩來傳遞。凸緣聯(lián)軸器結(jié)構(gòu)簡(jiǎn)單，制造方便，成本較低，工作可靠，裝拆、維護(hù)均較簡(jiǎn)便，傳遞轉(zhuǎn)矩較大，能保證兩軸具有較高的對(duì)中精度，一般常用于載荷平穩(wěn)，高速或傳動(dòng)精度要求較高的軸系傳動(dòng)。凸緣聯(lián)軸器不具備徑向、軸向和角向補(bǔ)償。剛性聯(lián)軸器是一種扭轉(zhuǎn)剛性的聯(lián)軸器，即使承受負(fù)載時(shí)也無任何回轉(zhuǎn)間隙，即便是有偏差產(chǎn)生負(fù)荷時(shí)，剛性聯(lián)軸器還是剛性傳遞扭矩。
