鼓型联轴器对轮间隙标准表

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.

对轮联轴器惯性主轴线与旋转轴线之间重心位置偏心量的可能值是平方和方根值而决定的，主要由两半联轴器和联接螺栓组成，对轮联轴器轴套孔装配前，镗削切割和键槽的修整联轴器端面和其它表面的加工等。半联轴器的轴套孔有圆锥孔和圆柱孔两种形式，圆锥孔比圆柱孔在工艺特性上有较多的特点，圆锥形轴套孔容易获得相配合部件之间的同心。

对轮联轴器在工作过程中，并且会带来燃油消耗空气污染等后果，由于承受咬入冲击动载荷，使得联轴器受到峰值转矩，联轴器承载能力下降，并在短时间内失效，从而直接影响其正常工作，其中的较薄弱环节进行替换或维修是重要和实用的。联轴器两轴相对半径变位要求较好，找耦合同心度为0.2~0.6mm，存在很大困难。如果在驾驶过程中螺栓松动，泵装置的振动和噪音可能会变大。
