為什么在重型提升機(jī)應(yīng)用中使用正確的聯(lián)軸器很重要

Why The Right Coupling Matters In Heavy-Duty Hoist Applications

起重機(jī)和提升機(jī)性能由它們的聯(lián)軸器所決定，聯(lián)軸器對(duì)于維持機(jī)器正常運(yùn)行時(shí)間和提高操作的安全可靠性至關(guān)重要。如果沒(méi)有正確的聯(lián)軸器，起重機(jī)或提升機(jī)可能無(wú)法正常工作，導(dǎo)致生產(chǎn)制造過(guò)程停頓。這種停機(jī)時(shí)間是不受歡迎的，尤其是在高負(fù)荷和昂貴設(shè)備的情況下。

在下面的文章中，我們將特別關(guān)注提升機(jī)，簡(jiǎn)要探討這些聯(lián)軸器是什么，以及您應(yīng)該尋找的設(shè)計(jì)特點(diǎn)。有兩種類(lèi)型的聯(lián)軸器，可滿足起重機(jī)和提升機(jī)應(yīng)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.

鼓形聯(lián)軸器 – 高負(fù)荷、操作安全

提升機(jī)使用卷筒或提升輪提升和降低負(fù)載，繩索或鏈條圍繞卷筒或提升輪纏繞。提升機(jī)可以手動(dòng)操作，也可以電動(dòng)或氣動(dòng)驅(qū)動(dòng)，并使用鏈條、纖維或鋼絲繩作為提升介質(zhì)。從鋼廠到制造工廠，提升機(jī)被廣泛在包括上下移動(dòng)大型重型產(chǎn)品等應(yīng)用中。

一種用于提升機(jī)的成熟聯(lián)軸器，鼓形聯(lián)軸器連接卷筒和齒輪箱輸出軸，也用于絞車(chē)輸送機(jī)和平臺(tái)提升機(jī)。

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.

靈飛達(dá) TNK 鼓形聯(lián)軸器

這些聯(lián)軸器通過(guò)鼓形的硬化銷(xiāo)傳遞扭矩，這些銷(xiāo)安裝在軸和轂之間的半圓形機(jī)加工孔洞中 – 保證徑向力安全傳遞。

鼓形聯(lián)軸器起著鉸接接頭的作用，使卷筒和齒輪箱之間靜定連接，并避免高彎矩。它們還允許安裝誤差、結(jié)構(gòu)變形和正常磨損引起的角度偏差和軸向偏移。沒(méi)有這些聯(lián)軸器所提供的靈活性，由交變彎曲載荷產(chǎn)生的力會(huì)導(dǎo)致軸斷裂和其他代價(jià)高昂的破壞性損壞。

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.

齒輪聯(lián)軸器 – 高扭矩、小尺寸

另一個(gè)通常在提升機(jī)中發(fā)現(xiàn)的聯(lián)軸器是齒輪聯(lián)軸器，它連接驅(qū)動(dòng)電機(jī)和齒輪箱。它還可以使用法蘭將齒輪箱直接連接到較小的鋼絲繩卷筒上。

齒輪聯(lián)軸器通過(guò)帶有鼓形齒的軸轂傳遞扭矩，這些齒與軸轂的直齒輪齒連續(xù)嚙合-這種設(shè)計(jì)在最小尺寸下提供了最高的扭矩傳遞。它們也可高速運(yùn)行，符合美國(guó)齒輪制造業(yè)協(xié)會(huì)AGMA的螺栓連接模式，并補(bǔ)償角度、徑向和軸向的不對(duì)中。

我們的齒輪聯(lián)軸器有多種尺寸可供選擇，是對(duì)我們?yōu)槠鹬貦C(jī)和提升機(jī)市場(chǎng)提供的廣泛聯(lián)軸器的補(bǔ)充（左：RINGFEDER TNZ-ZCAK-ZCBK）- 使您的選擇過(guò)程比以往任何時(shí)候都更容易。在這里了解更多有關(guān)我們的鼓形和齒輪聯(lián)軸器的信息

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.
