As custom coupling is commonly used in different machines, it becomes more important to know why it can be used variously and how to choose a suitable custom coupling. Our clients are unfamiliar with types and usage of shaft couplings. We hope we can provide you with some information about custom coupling.

What are the features of custom coupling?

Custom couplings have the ability of buffering, dampening, and improving the dynamic performance of the shaft system. Sometimes custom coupling is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection.

Custom coupling is often composed of two halves, which are connected by a key or tight fit respectively, and fastened to the ends of the two shafts, and then the two halves are connected in some way. The custom coupling can also compensate the deviation between the two shafts due to inaccurate manufacturing and installation and deformation or thermal expansion during work.

  • Excellent torque transmission: Rigid couplings can efficiently transfer torque from one shaft to the other connected shaft.

  • Low cost of production: Manufacturers can produce standard and custom rigid couplings at cost-effective rates.

  • Precision, with nearly zero windup and zero backlash

  • Torsional stiffness: High torsional stiffness allows for better positioning.

  • Alignment capabilities: Rigid couplings can be used to establish shaft alignment between the motor and connected components.

  • Suitability for push-pull and support applications

  • Easy assembly, disassembly, and maintenance operations throughout the life of the custom coupling.


How to choose a suitable custom coupling?

According to the size of the transferred load, the speed of the shaft, and the installation accuracy of the two parts to be connected, choose a suitable custom coupling, together with referring to the characteristics of various couplings. The following points can be considered when selecting:

The size and nature of the torque to be transmitted and the requirements for the cushioning function. For example, for high-power and heavy-duty transmissions, gear couplings can be selected. For transmissions that require severe impact loads or to eliminate shaft torsional vibration, tire couplings and other couplings with high elasticity can be selected.

The working speed of the custom coupling and the centrifugal force. For high-speed transmission shafts, custom couplings with high balance accuracy, such as diaphragm couplings should be selected, rather than slider couplings which has eccentricity.

The magnitude and direction of the relative displacement of the two axes. When it is difficult to maintain strict and precise alignment of the two shafts after installation and adjustment, or when the two shafts will have a large additional relative displacement during the working process, a flexible coupling should be used.

The reliability and working environment of the custom coupling. Custom coupling usually made of metal elements that do not require lubrication are more reliable. The performance of custom coupling is easily affected by the perfect degree of lubrication and may pollute the environment.

Custom coupling containing non-metallic components such as rubber are sensitive to temperature, corrosive media and strong light, and are prone to aging. The surrounding working environment of custom coupling is more complicated.

Temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive media, salt water, and radiation are all should be taken into consideration when choosing a custom coupling. For the working quality of high or low temperature, oil, acid and alkali medium, it is not suitable to choose the flexible coupling with the general rubber as the elastic element material.

The manufacturing, installation, maintenance and cost of the custom flexible coupling. Under the premise of meeting the convenience performance, custom coupling that are easy to install and unload, simple to maintain, and low-cost should be selected. For example, the rigid coupling has simple structure and convenient assembly and disassembly, and can be used for low-speed, high-rigidity drive shafts.


What is the present condition of custom coupling?

The custom shaft coupling industry in our country has developed since the establishment of PRC. After decades of construction and development, our custom shaft coupling industry has formed an independent industrial system of considerable scale and certain level since the reform and open policy.

In the development process, there are more guarantees and space for improvement both in terms of quantity and quality. However, gaps exist between the number of custom shaft couplings and the development needs of the national economy.

At present, although domestic scientific research personnel can produce some scientific research results about custom shaft couplings that are considered advanced in the country, these results are not competitive when they are obtained internationally. Nowadays it is necessary to improve the level of specialized production of custom couplings, as well as improving the production organization of custom coupling enterprises.

The delivery cycle of the custom coupling is the most important that it has become a trend to require coupling production companies to deliver as soon as possible. Some companies continue to change the technical level, equipment level, and management level to improve efficiency in order to shorten the delivery cycle.

Custom Alloy couplings will inevitably develop to a wider range and higher level. Chinese shaft coupling companies should seize the opportunity to borrow and learn advanced foreign technologies to accelerate pace of development.
