鼓形齿联轴器选型需比输出扭力

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.

扭力限制器又名扭矩限制器、力矩限制器、BMOOM限制器等，其价格便宜、结构简单、方便拆装维护、过载后反应速度快、设定扭矩精确度高、使用寿命更长，配一个微型开关过载后能输出电信号以方便报警或自动停掉电机。扭力联轴器广泛应用于电子装备行业、自动化生产线、输送机行业等。

扭矩联轴器是联接主动机与工作机的一种部件，主要功能为过载保护，力矩联轴器是当超载或机械故障而导致所需扭矩超过设定值时，它以打滑形式限制传动系统所传动的扭力，打滑的同时也能一个信号输出停掉电机和减速机，当过载情形消失后自行恢复联结。

扭矩安全联轴器螺帽或螺栓调整弹簧力，预设其滑动扭矩。按工作原理可分为摩擦式扭矩限制器和钢球式扭矩限制器(滚珠式扭矩限制器)，安全离合器应用范围:电子装备行业、自动化生产线、输送机行业等。
