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)，優化了很多細部(bu)尺寸鏈，采用(yong)了大壓(ya)力(li)角齒形(xing)設(she)(she)計，軸孔采用(yong)短(duan)軸設(she)(she)計，縮(suo)小了長徑比，結構更加緊湊，轉速性(xing)(xing)能優異。相近型號的螺(luo)栓采用(yong)標準統一化，零部(bu)件通(tong)用(yong)性(xing)(xing)好。

與國家標準齒式聯軸器相比能(neng)夠(gou)傳遞更(geng)大(da)(da)的扭矩，質(zhi)量相對(dui)大(da)(da)幅度(du)減輕(qing)，轉(zhuan)動(dong)(dong)慣量小(xiao)，符(fu)合歐洲防爆要求，各種綜合性能(neng)大(da)(da)大(da)(da)超前。為了更(geng)好的傳動(dong)(dong)性能(neng)，我們(men)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)遞較大的扭矩和允許較大的角位移，性能優異且壽命更(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.

靠背輪聯軸器用來(lai)將不同機構中的(de)主動軸和(he)從動軸牢(lao)固地聯接起(qi)來(lai)一同旋轉(zhuan)，并(bing)傳遞(di)運動和(he)扭(niu)矩的(de)機械部件。有時也(ye)用以聯接軸與其他零件（如齒輪(lun)、帶(dai)輪(lun)等）。

靠背輪常由兩(liang)(liang)半合成，分別用(yong)鍵(jian)或緊(jin)配合等聯(lian)(lian)接，緊(jin)固在兩(liang)(liang)軸端，再通過某(mou)種方式將兩(liang)(liang)半聯(lian)(lian)接起來。

靠背(bei)輪(lun)聯軸(zhou)(zhou)(zhou)器可兼有補償兩軸(zhou)(zhou)(zhou)之間由于制造安裝(zhuang)不精確、工作時的變形或熱膨脹(zhang)等原因所發生(sheng)的偏(pian)移(yi)（包括軸(zhou)(zhou)(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(he)沖擊、吸振。

靠背輪為俗稱，專(zhuan)業叫法為聯軸器以及法蘭，用(yong)于機械設備的(de)連接。
