鼓形齿式卷筒联轴器标准号

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.

卷筒联轴器是起重设备传动系统中重要的的部件， 通过其连接减速机动力输入轴和卷筒契合，传递扭矩同时限制卷筒的轴向窜动，并且带有机械或者电子磨损报警，是卷筒式提升机构的核心部件之一。

卷筒联轴器是一种新型挠性联轴器，主要用于起重设备中起升机构的减速器输出轴与钢丝绳卷筒的联接，也适用于其它类似的既传递转矩又承受径向载荷的机械设备，但不能用作需承受轴向载荷的传动。

卷筒联轴器由带鼓形齿的外齿轴套、带联接法兰和内齿圈的外套、带外球面的承载环、端盖和密封圈等组成，并设有定位磨损指针、润滑油孔和通气孔等。

外齿轴套和外套构成的鼓形齿式联轴器传递驱动功率, 而由承载环的外球面和外套的内承载面形成的接触副构成自动调位的球面轴承，承受径向载荷。联轴器的内、外齿啮合在油浴中工作,通过内外端盖、密封圈防止润滑脂泄漏。
