为什么在重型提升机应用中使用正确的联轴器很重要

Why The Right Coupling Matters In Heavy-Duty Hoist Applications

起重机和提升机性能由它们的联轴器所决定,联轴器对于维持机器正常运行时间和提高操作的安全可靠性至关重要。如果没有正确的联轴器,起重机或提升机可能无法正常工作,导致生产制造过程停顿。这种停机时间是不受欢迎的,尤其是在高负荷和昂贵设备的情况下。

在下面的文章中,我们将特别关注提升机,简要探讨这些联轴器是什么,以及您应该寻找的设计特点。有两种类型的联轴器,可满足起重机和提升机应用中的可靠性和安全性要求。

Cranes and hoists are only as good as their couplings, which are essential to maintaining uptime and enhancing the safety and reliability of your operation. Without the right coupling, your crane or hoist may not function properly, causing your manufacturing process to grind to a halt. This kind of downtime is not welcome – especially where very high loads and expensive equipment are concerned.

In the following we will focus specifically on hoists, briefly explore what these couplings are and the design features you should look for. There are two types of couplings that meet the demands for reliability and safety in crane and hoist applications.

鼓形联轴器 – 高负荷、操作安全

提升机使用卷筒或提升轮提升和降低负载,绳索或链条围绕卷筒或提升轮缠绕。提升机可以手动操作,也可以电动或气动驱动,并使用链条、纤维或钢丝绳作为提升介质。从钢厂到制造工厂,提升机被广泛在包括上下移动大型重型产品等应用中。

一种用于提升机的成熟联轴器,鼓形联轴器连接卷筒和齿轮箱输出轴,也用于绞车输送机和平台提升机。

Barrel Couplings – High Loads, Safe Handling

Hoists lift and lower loads using a drum or lift-wheel, around which a rope or chain wraps. Hoists can be manually operated, as well as electrically or pneumatically driven, and utilize chain, fiber or wire ropes as their lifting medium. From steel mills to manufacturing plants, hoists are used in wide range of applications that involve moving large, heavy products up and down.

A well-proven coupling for hoists, barrel couplings connect the cable drum with the gearbox output shaft and are also used in winch conveyors and platform hoists.

 

 

灵飞达 TNK 鼓形联轴器

这些联轴器通过鼓形的硬化销传递扭矩,这些销安装在轴和毂之间的半圆形机加工孔洞中 – 保证径向力安全传递。

鼓形联轴器起着铰接接头的作用,使卷筒和齿轮箱之间静定连接,并避免高弯矩。它们还允许安装误差、结构变形和正常磨损引起的角度偏差和轴向偏移。没有这些联轴器所提供的灵活性,由交变弯曲载荷产生的力会导致轴断裂和其他代价高昂的破坏性损坏。

RINGFEDER TNK Barrel Coupling

These couplings transmit torque via barrel-shaped hardened pins that fit into semicircular, machined openings on the hub and sleeve – ensuring radial forces are transmitted safely.

Barrel couplings perform the function of an articulated joint, making the connection between the cable drum and gearbox statically determinate and avoiding high bending moments. They also allow angular and axial shaft misalignment caused by mounting inaccuracies, structural deformation and normal wear and tear. Without the flexibility provided by these couplings, the forces generated by the alternating bending loads can lead to shaft breakage and other costly, disruptive damages.

齿轮联轴器 – 高扭矩、小尺寸

另一个通常在提升机中发现的联轴器是齿轮联轴器,它连接驱动电机和齿轮箱。它还可以使用法兰将齿轮箱直接连接到较小的钢丝绳卷筒上。

齿轮联轴器通过带有鼓形齿的轴毂传递扭矩,这些齿与轴毂的直齿轮齿连续啮合-这种设计在最小尺寸下提供了最高的扭矩传递。它们也可高速运行,符合美国齿轮制造业协会AGMA的螺栓连接模式,并补偿角度、径向和轴向的不对中。

我们的齿轮联轴器有多种尺寸可供选择,是对我们为起重机和提升机市场提供的广泛联轴器的补充(左:RINGFEDER TNZ-ZCAK-ZCBK)- 使您的选择过程比以往任何时候都更容易。在这里了解更多有关我们的鼓形和齿轮联轴器的信息

Gear Couplings - High Torque, Small Package

Another coupling typically found in hoists is the gear coupling, which connects the drive motor and gearbox. It can also connect the gearbox directly to smaller wire rope drums using a flanged.

Gear couplings transmit torque via hubs with crowned gear teeth, which are in permanent mesh with the straight gear teeth of the sleeves – a design that provides the highest torque transmission for the smallest size. They also run at high speeds, conform to the AGMA bolting pattern and compensate for angular, radial and axial shaft misalignment.

Available in a variety of sizes, our gear couplings complement our extensive coupling offering for the crane and hoist market (left:RINGFEDER TNZ-ZCAK-ZCBK) – making your selection process easier than ever. Learn more about our barrel and gear couplings here.
