Shaft Coupling

In recent years, linking pieces of transmission technology and application development trends are as follows: First, with the host, and support a comprehensive analysis of the load. Such as construction machinery, vehicles, vessels powertrain, pieces need to link the characteristics of transmission and engine and mechanical characteristics of the load analysis, thereby linking pieces to drive the best choice. Second is the transmission link pieces of the continuous improvement of quality requirements, which for raw materials, processing and assembly technology, products, processes and final inspection requirements greatly enhanced. Third, as the host of changes in requirements and technology development needs, linked to the transmission parts of the technology development and more emphasis on technology development. Fourth, transmission link to the matching pieces of their own professional development. Such as clutch, brake friction materials, the flexible coupling components, clutch, brake hydraulic, pneumatic and electrical components, and even forging, heat treatment and standard parts are more specialized support. Fifth, the exchange of information, including market information, technical information, user information, product information, to become even more important. Sixth, in a highly competitive technological development is all the more important in this regard not only technical problems, more funds needed in today's foreign co-financing, joint development, sharing the results of the joint development of the trend.

Electric power transmission is the bulk transfer of electrical energy, a process in the delivery of electricity to consumers. A power transmission network typically connects power plants to multiple substations near a populated area. The wiring from substations to customers is referred to as electricity distribution, following the historic business model separating the wholesale electricity transmission business from distributors who deliver the electricity to the homes.[1] Electric power transmission allows distant energy sources (such as hydroelectric power plants) to be connected to consumers in population centers, and may allow exploitation of low-grade fuel resources such as coal that would otherwise be too costly to transport to generating facilities.

China's annual requirements of various types, size, coupling the large number of specifications, together with spare parts and the volume of exports has increased year by year, the demand will be greater, so the coupling has a very broad market. Although the coupling of a large market, but also a number of specialized manufacturers, the annual sales of nearly more than one billion yuan, but it can only meet the general needs. The high content of technology, manufacturing is very difficult, life-long large-scale coupling or fail, only a very small number of national manufacturers can produce. China's sales of the lack of standardization of coupling, since only a small number of users attention to the price of neglecting the quality of the phenomenon of the formation of each other to keep the prices down, the price and some even less than cost price, can not guarantee the quality and disturb the market order. There is also a small number of professional manufacturer and has not formed a certain scale, backward technology, obsolete equipment, it is difficult to produce high-quality products, and therefore lost some of the market.

Coupling is a mechanical problem, the coupling is very important to find, motor (including the servo motor) and a similar lead screw connected to the follower side, almost every use; even the axis of the connecting device has a variety of ways, with a total The link is divided into hard and soft links.

Any rotating parts are potentially dangerous, the user application to coupling guard properly protected. To ensure the machines and the coupling of long-life work, the user must choose and install the correct coupling. 1. Detection of the distance between the two Shaft End: ...

With regard to the choice of coupling: Consider the choice of coupling needed to pass major axis of the high and low speed, load size, the two connected components, such as the installation of accuracy, a smooth rotation, and price and so on, refer to the characteristics of various types of coupling, choose a combination of coupling types. Specific options to be taken into account the following points: ...
