Custom coupling is designed for special use of working condition, where the standard type of shaft couplings cannot meet the requirements. Custom 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. Custom coupling should be used in different machines because the two shaft couplings have advantages and disadvantages.

Shaft coupling is a part of general mechanical parts of machinery, which is used to connect two shafts, namely the movable shaft and the driven shaft, in different main bodies so that they can rotate together to transmit torque. In high-speed and high-power transmission, some shaft couplings also have the functions of buffering, damping and improving the dynamic performance of the shafting. The shaft coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.
In the late 20th century, shaft coupling products at home and abroad developed rapidly. It is always a problem that how to choose the performance of various shaft couplings to meet the requirements of the shaft coupling on the machine. Custom coupling can commonly be made as diaphragm couplings, drum gear couplings, universal couplings, safety couplings, elastic couplings and serpentine spring couplings.
The custom coupling is a component of the two-axis axial joint and transmitting torque and motion, which has a certain compensation for the deviation of the two shafts. Custom coupling can reduce the vibration of the mechanical transmission system and reduce the peak impact load.
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 micro precision 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.
If there is no suitable shaft coupling that you can find in the standard list, you can ask the plant to do a custom coupling. Here are some shaft couplings that can be used for:
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 custom 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.
