Shaft couplings can be divided into two main types: rigid couplings, which connect two shafts with a solid and high-precision hold, and flexible couplings, which can be used to connect slightly misaligned shafts but which can’t provide the same level of torque transfer. While both shaft coupling have their advantages and disadvantages, it’s important to know which shaft coupling to choose in a particular application.
What is the difference between rigid shaft coupling and flexible shaft coupling?
What basic performance that shaft coupling should be reached?
What shaft coupling can be used for?
Rigid shaft coupling cannot compensate for the axial displacement and radial displacement between the connecting transmission shafts. The rigid coupling has a simple structure and a low price, which is suitable for two shafts with good concentricity.
Flexible shaft coupling can compensate for the axial displacement and radial displacement between the connecting shafts. The structure of the flexible coupling is relatively complicated and the price is relatively high. It is suitable for the situation where the concentricity of the two shafts is not very good, and is suitable for the situation with torsional vibration to reduce vibration.
The main difference between rigid couplings and flexible couplings is the connection they provide. Rigid coupling provides a rigid connection, that is, two shafts are firmly connected, and the coupling can transmit torque smoothly in the entire system. A flexible coupling can form a flexible connection, and the components may lose some torque through interaction.
When the shaft coupling is used, it must achieve some standard basic performance. According to the different conditions of the work, shaft coupling also needs to achieve a better use effect, so that it can take specific use advantages and show normal use significance. So, let’s give you a comprehensive introduction to the performance standards that the shaft coupling should play in the working process.
The shaft coupling must be movable in the process of use, which can play a better compensation effect and can meet everyone's needs for the working process. The mobility of the shaft coupling is the ability to compensate the displacement of the two rotating components to have a better compensation for errors in component manufacturing and installation, and avoid the influence of temperature changes on the deformation of components. In addition to being able to meet the mobility performance standard, shaft coupling is also necessary to achieve better buffering and dampening. For load starting or working in and changing places, it is necessary to use shaft couplings for buffering and dampening, which can achieve better reduction. The vibration effect can also exert a better elastic effect, so try to ensure that the prime mover and working machine are less damaged, or not damaged as much as possible, so that the service life of the mechanical equipment is longer.
Regarding the performance of the shaft coupling, it is recommended that you must understand the above content, so that the application process can achieve better results, and it can also meet everyone's specific needs, and it can also show the performance advantages better.
Sleeve and muff coupling and clamp or split-muff or compression coupling can both be used as line shaft in power transmission.
Flange coupling can be used for Alignment Accuracy, for example, marines.
Bushed pin flexible coupling can be used to connect which have small parallel misalignments, angular misalignment or axial misalignments, for example, automobiles.
Universal joint can be used to transmit rotary motion or power, for example, aircraft, driveshafts and so on.
Oldham coupling is useful in applications where parallel misalignment is present, for example, printing applications.
Unlike other shaft couplings, the slider coupling does not have an elastic element that can work like a spring, so the bearing load will not increase due to the increase in the relative displacement between the shafts. In any case, this series of shaft couplings is more worthwhile, and the ability to choose sliders of different materials is the biggest advantage of this shaft coupling. Generally speaking, one type materials are suitable for zero clearance, high torque rigidity and large torque, and the other type materials are suitable for low-precision positioning, without zero clearance, but have the functions of absorbing vibration and reducing noise. The non-metallic slider also has excellent electrical insulation and can be used as a mechanical fuse. When the engineering plastic slider is damaged, the transmission effect will be completely terminated, so as to protect the valuable mechanical parts. This design is suitable for large parallel relative displacements. The separate three-part design of the slider coupling limits its ability to compensate for axial deviations, for example, it cannot be used in push-pull applications. At the same time, because the center slider is floating, the two-axis movement must ensure that the slider does not fall off.
The elastic element of the bellows coupling is a precision metal bellows, which can be divided into two types: flexible series and rigid series. The flexible bellows couplings have greater flexibility and are often used in miniature applications such as encoders and sensors, which the rigid bellows couplings are mainly used in applications such as electrical machinery and CNC machine tools.
