鼓型齒式聯(lián)軸器是一種特別設(shè)計的先進(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.

柱銷聯(lián)軸器是利用一端套有彈性套（橡膠材料）的柱銷，裝在兩半聯(lián)軸器凸緣孔中，以實(shí)現(xiàn)兩半聯(lián)軸器的聯(lián)接。

彈性柱銷聯(lián)軸器是一種結(jié)構(gòu)簡單制造容易，無需潤滑，裝拆彈性柱銷便捷的傳動基礎(chǔ)件，利用兩個帶法蘭孔的半聯(lián)和置于起重的非金屬彈性柱銷來傳遞扭矩，適用于中低速和中低扭矩場合。

彈性柱銷齒式聯(lián)軸器采用非金屬彈性柱銷和兩個帶齒形半聯(lián)以及一個外圈的齒形套環(huán)設(shè)計，利用非金屬彈性的變形來傳遞扭矩同時緩沖減震，補(bǔ)償角向位移。

彈性套柱銷聯(lián)軸器設(shè)計簡單巧妙，適用性較廣的聯(lián)軸器，利用帶彈性套的柱銷聯(lián)接兩個帶銷孔的半聯(lián)，實(shí)現(xiàn)扭矩傳遞的同時兼具較大的角向補(bǔ)償，同時減震緩沖性能良好，可以用在速度較快的場合，無需潤滑，銷套更換便捷。

The pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement. The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions. The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, Pin and bush couplings has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
