Product Details
A coupling is a mechanical component that is used to firmly connect the driving shaft and driven shaft in different mechanisms together, rotate together, and transmit motion and torque. It is also sometimes used to connect shafts and other parts (e.g. gears, pulleys, etc.). It usually consists of 2 parts, which are connected by a key or clamping fit, respectively, and fastened at the 2 shaft ends. Couplings can compensate for deviations (including axial, radial, angular or combined offset) between 2 shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during operation, as well as shock and vibration absorption. The most commonly used couplings have been standardized or normalized. In general, it is only necessary to select the type of coupling correctly and determine the type and size of the coupling. If necessary, check and calculate the carrying capacity of the vulnerable and weak links; When the rotational speed is high, it is necessary to check the centrifugal force on the outer edge and the deformation of the elastic element for balance detection.
Couplings are used to connect shafts in different mechanisms, mainly by rotation, thus transferring torque. Under the action of high-speed power, the coupling has the function of buffering and damping, and the coupling has good service life and working efficiency.
The function of the coupling:
a device that connects 2 shafts or shafts with rotating parts and rotates together in the process of transmitting motion and power and does not break away under normal circumstances. Sometimes, it is also used as a safety device to prevent the connected parts from bearing excessive loads and play the role of overload protection. The coupling is installed between the active side and the passive side of the power transmission, which plays the role of transferring torque, compensating the installation deviation between shafts, absorbing equipment vibration and buffering load impact. One of the functions of couplings is to absorb and compensate for deviations between shafts through their own deformation. The greater the elasticity, the stronger the ability to absorb the deviation; The less flexibility you have, the less ability you have to absorb deviations. In general, the deviation between the shaft and the shaft can be divided into the following 3 aspects: The connection between the coupling and the peripheral equipment is achieved by inserting the shaft of the device into the shaft hole of the coupling.
1. The role of the coupling is to connect the 2 shafts in different mechanisms (drive shaft and driven shaft) to rotate and transmit torque together, and some couplings also have the role of buffering, damping and improving the dynamic performance of the shafting.
2. Eliminate the inertia of the radial force, connect the motor spindle with the load, and use a coupling to weaken the starting power when the motor starts.
3. Power conduction, transmission of power and torque (improve the performance of the transmission system)
4. Different degrees of vibration reduction and buffering
5. Disconnect when the load is too large to play a protective role
6. Good for maintenance
7. Change the drive direction
8. Concentricity correction (different degrees of axial, radial and angular compensation performance)
The types of couplings
Bellows coupling
The bellows coupling is composed of 2 hubs and thin-walled bellows that are welded or bonded together. The input end of the coupling structure is a clamping structure, and the pre-tightening force is generated by clamping screws, and the power input shaft is firmly connected with the clamping hoop. Flexible and rigid stainless steel bellows have the ability to correct radial, axial and angular deviations, transmit torque with zero backlash, and have different bushings designed to meet different equipment requirements.
A plum coupling
Plum coupling is a widely used coupling, elastomer is a balance accessory, can zero back backlash transfer torque and shock absorption. The different types of elastomers determine the characteristics of the entire drive system. Zero back backlash is achieved through a pre-pressure between the 2 coupling bushing and the elastomer. Its elastomer is usually composed of engineering plastics or rubber. Because elastomers have the function of buffering and reducing vibration, they are widely used in the case of strong vibration.
Safety coupling
The safety coupling mainly relies on the spring force and works with the shape, which can protect the adjacent drive components from damage caused by overload. Divided into synchronous type, stepping type 60°, failure protection type, closed. Features of a special butterfly spring system. No torque transfer is possible until the torque control nut is linked to the butterfly spring to apply pressure. The service life of the safety coupling is largely determined by the speed at which the coupling is disengaged and the holding time of the coupling. The safety coupling is not worn when it is engaged, does not require maintenance, and does not require additional refueling.
Rigid coupling
The rigid coupling is actually a torsional rigid coupling. Even under load, there is no turning clearance. Even if there is a deviation that creates a load, the rigid coupling is still rigid to transmit torque. Rigid couplings need to be used to connect 2 shafts in strict alignment without relative misalignment, so they are used less in motor test systems. Of course, if the relative displacement can be successfully controlled (the alignment accuracy is high enough), rigid coupling can also play an excellent role in the application. In particular, the small size rigid coupling has the advantages of light weight, ultra-low inertia and high sensitivity. In practical applications, rigid couplings have the advantages of maintenance-free, ultra-oil resistance and corrosion resistance.
Long shaft coupling
The standard length of the long-shaft coupling is up to 6 meters, and no intermediate support is required. The 2 ends are connected by high-performance stainless steel or high-strength aluminum, and the middle pipe is made of different materials such as steel, aluminum or carbon fiber. The allowable deviation range, speed and torque of the standard model should be reduced by 30%. The allowable working speed depends on the total length of the joint shaft and can also be adjusted according to demand.
Diaphragm coupling
Diaphragm couplings transfer torque by friction and diaphragm assembly, so there are no stress concentrations, backbacklash and micro-displacement that occur when torque is transferred through shoulder bolts. It has a near unlimited service life and increases the torsional rigidity of the individual components of the complete coupling, which can compensate for a variety of combined shaft assembly errors as a percentage of the total allowable error value listed in the data sheet. The sum of the percentages of the 3 errors cannot exceed 100%.

在为特定应用选择合适的传动轴时，应考虑哪些因素？
在为特定应用选择合适的传动轴时，需要考虑多个因素。传动轴的选择对确保高效可靠的动力传输至关重要。以下是需要考虑的关键因素：
1. 功率和扭矩要求：
应用所需的功率和扭矩是至关重要的考虑因素。确定驱动轴在不发生故障或过度变形的情况下需要传递的最大扭矩至关重要。这包括评估发动机或动力源的功率输出，以及被驱动部件的扭矩需求。选择具有合适直径、材料强度和设计的驱动轴，对于确保其能够承受预期的扭矩水平而不影响性能或安全性至关重要。
2. 运行速度：
驱动轴的运行速度是另一个关键因素。转速会影响驱动轴的动态特性，包括振动、共振和临界转速限制的可能性。选择驱动轴时，必须确保其能够在所需转速范围内运行，且不会产生过大的振动或损害结构完整性。应考虑材料特性、平衡性和临界转速分析等因素，以确保驱动轴能够有效地承受所需的运行速度。
3. 长度和对齐方式：
选择传动轴时，必须考虑应用场景下的长度和对准要求。发动机或动力源与被驱动部件之间的距离决定了所需传动轴的长度。在长度或工作角度变化较大的情况下，可能需要使用伸缩式传动轴或带有合适联轴器或万向节的多根传动轴。传动轴的正确对准对于最大限度地减少振动、降低磨损以及确保高效的动力传输至关重要。
4. 空间限制：
应用空间的大小是一个需要考虑的重要因素。传动轴必须安装在预留空间内，且不得与其他部件或结构发生干涉。必须考虑传动轴的整体尺寸，包括长度、直径以及任何其他部件，例如接头或联轴器。在某些情况下，为了适应空间限制并保持足够的动力传输能力，可能需要定制或紧凑型传动轴设计。
5. 环境条件：
应评估传动轴的运行环境条件。温度、湿度、腐蚀性物质以及污染物等因素都会影响传动轴的性能和使用寿命。选择能够承受特定环境条件的材料和涂层至关重要，以防止传动轴腐蚀、性能下降或过早失效。对于暴露于极端温度、水、化学品或磨蚀性物质的应用，可能需要特别考虑。

这些例子表明，依赖传动轴进行高效动力传输和推进的车辆和机械种类繁多。传动轴是各行各业的关键部件，能够将动力从动力源传递到被驱动部件，最终实现运动、操作或特定任务的执行。
传动轴如何应对长度和扭矩要求的变化？
传动轴的设计旨在应对长度和扭矩需求的变化，从而高效地传递旋转动力。以下是对传动轴如何应对这些变化的解释：
长度变化：
传动轴有多种长度可供选择，以适应发动机或动力源与被驱动部件之间不同的距离。根据具体应用，传动轴可以定制，也可以购买标准长度的传动轴。在发动机与被驱动部件距离较长的情况下，可以使用多根带有合适联轴器或万向节的传动轴来连接。这些额外的传动轴有效地延长了动力传输系统的总长度。
此外，一些传动轴采用伸缩式设计。这些伸缩节可以伸长或缩回，从而调整长度以适应不同的车辆配置或动态运动。伸缩式传动轴常用于发动机与驱动部件之间距离可能发生变化的场合，例如某些类型的卡车、公共汽车和越野车。
扭矩要求：
传动轴的设计旨在满足不同的扭矩需求，这些需求取决于发动机或动力源的功率输出以及被驱动部件的要求。通过传动轴传递的扭矩取决于多种因素，例如发动机功率、负载情况以及被驱动部件所遇到的阻力。
制造商在选择传动轴的合适材料和尺寸时会考虑扭矩要求。传动轴通常采用高强度材料（例如钢或铝合金）制造，以承受扭矩载荷而不发生变形或断裂。传动轴的直径、壁厚和设计都经过精心计算，以确保其能够承受预期的扭矩，而不会出现过度挠曲或振动。
在重型卡车、工业机械或高性能车辆等高扭矩需求应用中，传动轴可能需要额外的加固措施。这些加固措施包括加厚壁厚、采用强度优化的横截面形状，或使用具有卓越扭矩承受能力的复合材料。
此外，传动轴通常采用柔性连接件，例如万向节或等速万向节（CV接头）。这些连接件允许一定的角度偏差，并补偿发动机、变速器和被驱动部件之间工作角度的变化。它们还有助于吸收振动和冲击，从而降低传动轴的应力，并提高其扭矩承受能力。
总而言之，传动轴通过可定制的长度、伸缩节、合适的材料和尺寸以及柔性接头的加入，来应对长度和扭矩需求的变化。通过仔细考虑这些因素，传动轴能够高效可靠地传递动力，同时满足不同应用的特定需求。
