主要产品
联轴器是指连接两根轴或轴与旋转部件的装置,在传递运动和动力时一起旋转,在正常情况下不会脱离。有时它也用作安全装置,防止连接部件承受过大的载荷,起到过载保护的作用。
耦合可以分为 刚性联轴器 和 柔性联轴器.
刚性联轴器不具备缓冲性能,也无法补偿两轴之间的相对位移,因此要求两轴必须严格对齐。然而,此类联轴器结构简单、制造成本低、装配、拆卸和维护方便,能够保证两轴相对中立,具有较大的传递扭矩,因此应用广泛。常用的刚性联轴器有法兰联轴器、套筒联轴器和夹套联轴器。
柔性联轴器还可以分为无弹性元件的柔性联轴器和有弹性元件的柔性联轴器。前者仅能补偿两轴的相对位移,但不能起到缓冲和减振的作用。常见类型包括滑块联轴器、齿轮联轴器、万向联轴器和链条联轴器;后者则包含弹性元件。除了能够补偿两轴的相对位移外,它还具有缓冲和减振的功能。但是,由于弹性元件的强度限制,其传递扭矩通常不如无弹性元件的柔性联轴器。常见类型包括: 弹性套筒销联轴器、弹性销联轴器、梅花形联轴器、轮胎式联轴器、蛇形弹簧联轴器、弹簧联轴器 ETC
Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CZPT requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.
How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

柔性联轴器如何处理角度、平行和轴向偏差?
柔性联轴器旨在适应两个旋转轴之间的各种不对中情况:角度不对中、平行不对中和轴向不对中。联轴器的柔性使其能够在补偿这些不对中情况的同时,保持轴之间的连接。以下是柔性联轴器如何处理每种不对中情况的说明:
- 角度偏差: 当两根轴的轴线不共线且彼此成一定角度时,就会发生角度不对中。柔性联轴器通过集成一个可弯曲变形的元件来处理角度不对中。一种常见的设计是“蜘蛛爪”或“爪形”元件,它由弹性材料制成。当轴发生不对中时,弹性元件可以发生轻微变形,从而使联轴器能够适应轴之间的角度偏移,同时仍能传递扭矩。
- 平行错位: 平行不对中,也称为偏移不对中,是指两根轴的轴线平行但并非完全对齐的情况。柔性联轴器可以通过同一弹性元件来处理平行不对中。该元件的柔性使其能够移动并调整以适应轴之间的偏移,从而确保动力连续传输,同时最大限度地减少机械设备的额外应力。
- 轴向错位: 轴向不对中,也称为端隙不对中,是指两根轴沿其共同轴线方向发生位移,导致轴之间的距离增大或减小。柔性联轴器可以通过特殊的设计来处理轴向不对中,这些设计允许有限的轴向位移。例如,一些联轴器采用开槽孔或浮动部件,允许轴向位移,同时保持轴之间的连接。
柔性联轴器能够处理角度、平行和轴向不对中,因此为动力传输系统提供了诸多优势:
- 它们有助于防止连接的设备过早磨损和损坏,从而降低维护和更换成本。
- 它们最大限度地减少了振动和冲击载荷,提高了机械的整体平稳性和可靠性。
- 它们降低了因不对中引起的应力而导致设备故障的风险,从而延长了系统的使用寿命。
- 它们便于安装和调整,从而节省安装和维护的时间和精力。
总体而言,柔性联轴器在处理不对中问题和确保各种工业应用中的高效动力传输方面发挥着至关重要的作用。

柔性联轴器如何影响连接设备的整体可靠性?
柔性联轴器会从多个方面显著影响连接设备的整体可靠性:

- 冲击载荷吸收: 在重型机械或高速设备等负载突变或冲击载荷应用中,柔性联轴器可起到减震器的作用。它能够吸收和耗散冲击能量,保护机械免受突发载荷造成的损坏。吸收冲击载荷的能力有助于提高连接设备的整体可靠性。
- 减少磨损: 联轴器的灵活性最大限度地减少了旋转设备的应力和磨损。它允许轻微的移动和不对中,从而减少轴承和其他关键部件的摩擦和应力。磨损的减少降低了维护和更换的频率,提高了设备的整体可靠性。
- 热膨胀补偿: 机械设备的温度变化会导致轴的热膨胀或收缩。柔性联轴器可以补偿这些热效应,确保机械设备即使在温度波动的情况下也能保持正确的对准。这种补偿可以防止卡滞和不对中,从而提高设备的可靠性。
- 过载保护: 柔性联轴器有助于保护连接的设备免受过载和扭转振动的影响。它们如同机械保险丝,在发生过载时断开传动系统,从而防止昂贵的机械设备受损。这项安全功能提高了整体可靠性,并降低了发生灾难性故障的风险。
- 易于维护和校准: 柔性联轴器设计便于安装和对准。这一特性简化了维护程序,使联轴器的检查和更换更加便捷。正确对准的联轴器能够提升设备性能和使用寿命,从而提高整体可靠性。
通过补偿不对中、抑制振动、吸收冲击载荷、减少磨损以及提供其他保护功能,柔性联轴器显著提高了连接设备的可靠性。它延长了关键部件的使用寿命,最大限度地减少了停机时间,并确保了平稳高效的运行,使其成为各种工业应用中不可或缺的部件。
