齿式轮胎联轴器生产厂家

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.

轮胎联轴器采用轮胎体状橡胶元件，与两个半联经过螺栓联接，实现扭矩传递和位移补偿。橡胶轮胎联轴器具有较高的弹性性能，扭转刚度小，减震能力强，轴向补偿能力较大，有良好的阻尼性能。

弹性轮胎联轴器轮胎体是轮胎联轴器必要的备件之一，相应的分为UL、LA、LB轮胎体。轮胎式联轴器分为凸型和凹型两大类，凸型又分为带骨架整体式、无骨整体式和径向切口式三种。轮胎环内侧用硫化方法与钢质骨架粘接成一体，骨架上的螺栓孔处焊有螺母。装配时用螺栓与两半联轴器的凸缘连接，依靠拧紧螺栓使轮胎与凸缘端面之间产生的摩擦力来传递转矩，轮胎环工作时发生扭转剪切变形，故轮胎联轴器具有很高的弹性，补偿两轴相对位移的能力较大，并有良好的阻尼，而且结构简单、不需润滑、装拆和维护都比较方便。

轮胎式联轴器缺点是承载能力不高、外形尺寸较大，随着两轴相对扭转角的增加使轮胎外形扭歪，轴向尺寸略有减小，将在两轴上产生较大的附加轴向力，使轴承负载加大而降低寿命。轮胎联轴器高速运转时，轮胎外缘由于离心力的作用而向外扩张，将进一步增大附加轴向力。为此，在安装联轴器时应采取措施，使轮胎中的应力方向与工作时产生的应力方向相反，以抵消部分附加轴向力，达到改善联轴器和两轴承的工和条件。

轮胎式联轴器由于种种原因使其质心或惯性主轴与其加转轴线不重合，在运转时将产生不平衡离心惯性力、离心惯性力偶和动挠度（振型）的现象，称为转子的不平衡现象，这种不平衡现象必然引起轴系的振动，从而影响机器的正常工作和使用寿命，因而对其必须加以重视。

The tyre coupling adopts tyre body-shaped rubber elements, which are connected with two semi-couplings through bolts to realize torque transmission and displacement compensation. Tyre coupling has high elastic performance, small torsional rigidity, strong damping capacity, large axial compensation capacity, and good damping performance.
