蛇形弹簧联轴器齿形加工

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.

蛇形弹簧联轴器是一种结构先进的金属联轴器，它靠蛇形弹簧片来传递扭矩，蛇形弹簧联轴器是轴联接传动部件，也是一种非常通用的轴联接传动部件。蛇簧联轴器承受扭矩较大，适用于重型机械及通用机械场合。这种经过特殊工艺处的蛇形弹簧，具有很长的使用寿命　允许转速较高，在轴向、径向和角向具有良好的补偿能力。结构简单；拆装方便，使用寿命长；减振效果好，避免了共振。

蛇形联轴器共有九类型式，分别是JS罩壳径向安装型（基本型）、JSB罩壳轴向安装型、JSS双法兰联接型、JSD单法兰联接型、SJS接中间轴型、JSG高速型、JSZ带制动轮型、JSP带制动盘型、JSA安全型等。

蛇簧联轴器其主要结构是由两个半联轴节，两个半外罩，两个密封圈及蛇形弹簧片组成。它是靠蛇簧嵌入两半联轴节的齿槽内来传递扭矩，联轴器以蛇形弹簧片嵌入两个半联轴节的齿槽内，来实现主动轴与从动轴的链接。蛇型弹簧联轴器运转时，是靠主动端齿面对蛇簧的轴向作用力带动从动端，来传递扭矩，如此在很大程度上避免了共振现象发生，且簧片在传递扭矩时所产生的弹性变量，使机械系统能获得较好的减振效果，其平均减振率达36%以上。
