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(biao)準(zhun)技術，優化(hua)了(le)(le)(le)很多細部尺(chi)寸鏈，采(cai)用(yong)了(le)(le)(le)大壓力角齒形設(she)計，軸孔采(cai)用(yong)短軸設(she)計，縮小了(le)(le)(le)長徑比，結構更加緊(jin)湊(cou)，轉(zhuan)速性能優異。相(xiang)近(jin)型號(hao)的螺栓采(cai)用(yong)標(biao)準(zhun)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(neng)夠傳(chuan)遞更(geng)大(da)的扭矩，質量相對(dui)大(da)幅度減輕，轉(zhuan)動慣量小(xiao)，符(fu)合歐洲防爆要(yao)求(qiu)，各種綜合性(xing)能(neng)大(da)大(da)超前。為了更(geng)好的傳(chuan)動性(xing)能(neng)，我們強烈推薦(jian)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扭矩(ju)和允許較大的角位移，性能優(you)異(yi)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.

靠背輪聯軸器用來將不同機構中的(de)主動(dong)軸(zhou)(zhou)和(he)從動(dong)軸(zhou)(zhou)牢固地聯接(jie)起來一同旋(xuan)轉，并傳遞運動(dong)和(he)扭矩的(de)機械部件。有時也用以聯接(jie)軸(zhou)(zhou)與(yu)其他零(ling)件（如齒輪、帶輪等）。

靠(kao)背(bei)輪常由兩(liang)半合成，分別用鍵(jian)或(huo)緊配合等聯接，緊固(gu)在兩(liang)軸(zhou)端，再通(tong)過(guo)某種方式將兩(liang)半聯接起來。

靠背輪聯軸器可兼有(you)補償兩軸之間由(you)于(yu)制(zhi)造安裝不精確、工(gong)作時的(de)變形(xing)或(huo)熱膨脹等原因所發(fa)生的(de)偏(pian)移(yi)（包括軸向偏(pian)移(yi)、徑向偏(pian)移(yi)、角偏(pian)移(yi)或(huo)綜(zong)合偏(pian)移(yi)）；以(yi)及緩和沖擊、吸振。

靠背輪為俗(su)稱，專業叫法為聯軸器以及法蘭，用于機械設備的連(lian)接。
