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.

Scientific and technological achievements and new products

Coupling products in China since the 20th century has been rapid since the 80's the development of a variety of machinery and equipment to meet the needs of transmission system to meet the market demand, new products in emerging, has been gradually developed a more complete picture of the standard coupling system. In recent years, many companies in order to obtain greater economic benefits, more and more attention to new technologies, to this end have put a lot of human and material resources, with efforts to achieve a number of scientific and technological achievements, many have developed their own intellectual property rights, technology high levels of new products. Security such as the hydraulic coupling, through the crown gear-type coupling, through the cross-type universal joint, hardened drum gear coupling, high-elastic coupling, such as rubber. Scientific and technological achievements have been more than 20, more than a dozen patent applications.

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: ...

the right coupling selection No one type of coupling can provide the universal solution to all coupling problems; hence many designs are available, each possessing construction features to accommodate one or more types of application requirements. Rigid couplings can be employed in situations where shafts are precisely positioned without lateral or angular misalignment. For that reason rigid couplings are limited and are generally used in high horsepower applications. Flexible couplings allow some angular and parallel shaft misalignment and can cover a much larger field of applications. ...

Gear coupling are just flexible coupling, gear coupling is the same number of teeth with tooth ring gear and the flange-band semi-coupling components, such as spare parts. Outside the tooth is divided into straight-tooth and two tooth crown gear, the so-called crown gear teeth is to be made outside the sphere, spherical center axis in the gear, the gear side of space than the average gear, and drum gear coupling can be allow greater angular displacement (as opposed to straight-tooth coupling), can improve the tooth contact conditions, the ability to improve the transmission of torque to extend the service life. There are angular displacement along the tooth width at the contact state. With the radial, axial and angular deviation to the axis of compensation, such as capacity, with compact structure, small radius of gyration, the carrying capacity of large, high transmission efficiency, low noise and maintenance of long-term advantages, especially for low-speed heavy load operating conditions, such as metallurgy, mining, lifting and transportation industry, also apply to oil, chemicals, general machinery, such as various types of mechanical transmission shaft ...

Backlash-free shaft coupling (GS) Characteristics: under the non-prestressed connection Backlash for spindle drive, take-off and landing platform and tools, etc.; axial plug-in assembly for blind mounted, to save time; the size of small, small moment of inertia, maintenance-free; easy visual inspection. Middle elastomer polyurethane formulations used in Germany, there are a wide range of hardness to choose from. ...

Power transmission of China start very late, before the 80's 20th century,, there is no manufacturer specializing in the production of transmission parts , primarily provide OEM service. After the 80's 20th century, China drive to join the production of power transmission as market-oriented industry in recent years, the annual growth rate of about 30% and there have around 500 manufacturer specializing in torque limiter,shaft coupling,locking device and universal joints now. ...
