NL内齿式联轴器规格型号

ROD鼓形齿式联轴器是Rokee独立开发的核心技术传动产品之一并且在国家建立和报备了企业技术标准，结合了日本，德国等先进国家的鼓型齿联轴器标准技术，优化了很多细部尺寸链，采用了大压力角齿形设计，轴孔采用短轴设计，缩小了长径比，结构更加紧凑，转速性能优异。相近型号的螺栓采用标准统一化，零部件通用性好。

与国家标准齿式联轴器相比能够传递更大的扭矩，质量相对大幅度减轻，转动惯量小，符合欧洲防爆要求，各种综合性能大大超前。为了更好的传动性能，我们强烈推荐您选用。

鼓型齿式联轴器是一种特别设计的先进齿式联轴器，其外齿制成球面，球面的中心在齿轮的轴线上，齿侧的间隙比一般产品稍大，鼓形齿联轴器可以传递较大的扭矩和允许较大的角位移，性能优异且寿命更加长久。

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.

尼龙齿式联轴器是部分标准化生产的产品，在选择尼龙齿式联轴器的开始阶段，尼龙齿式联轴器无法找到适配类型，则可以进行定制生产。尼龙齿式联轴器型号调整还要考虑尼龙齿式联轴器连接的主动轴和从动轴之间的转速是否一样，轴径是否相同。尼龙齿式联轴器的联接形式是由主动轴和从动轴的连接形式来确定的，相对把比较采用的连接方式是键联接。

尼龙内齿式联轴器的品种和类型的选择是基于尼龙齿式联轴器在传动系统中发挥的综合功能来确定的，传动系统总体设计的因素，如原动机的类型、工作载荷的种类、原动机的转速、传动精度、轴偏移量、工作环境的状态，齿式联轴器在工作时，齿式联轴器需在有良好和密封的状态下工作，尼龙齿式联轴器初选过后应根据主动轴和从动轴的轴径、轴孔长度来确定尼龙齿式联轴器的尺寸。
