The relationship between the development of the coupling industry and the development of the steel industry

Introduce:

High-speed diaphragm coupling manufacturers will explain to you that couplings are more and more used in machinery controlled by servo systems. The difference between these couplings and general manufacturing machinery is that the output is required to have a high output relative to the input. In recent years, due to the development of the servo motor industry, the need to adapt to high speed and control has been exaggerated more and more.

Coupling industry development:

Near couplings are increasingly being used in machines controlled by servo systems, such as machine tools and semiconductor system manufacturing machines. Among these, unlike general manufacturing machinery, the coupling requires a high followability of its output relative to its input.

Especially when used on machine tools that require high-frequency forward and reverse rotation, positioning, and high-speed rotation above 20,000r/min, the coupling not only has high rigidity itself, but also has the ability to withstand repeated torsional loads and high elastic fatigue limits. , to adapt to high-speed operation. Therefore, the coupling originally has the characteristics of high torque rigidity, zero backlash, elastic body compensation for the radial, axial, and angular deviations of the two shafts during the transmission process of the manufacturing machine, and the characteristics of clockwise and counterclockwise rotation are equal.

In the past, people only considered the coupling as a mechanical component. However, with the diversification of the use of the mechanical device itself, in order to achieve the desired function, the familiarity with the coupling has changed from a simple mechanical component. It is transformed into an important mechanical element that can influence the function of the entire mechanical system.

Therefore, it is becoming more and more difficult to meet the requirements of users only by the independent products of coupling manufacturers. Now, it has become a trend for users and manufacturers to work together to jointly meet the requirements of the mechanical system. The direct metal material of the coupling is steel, so the development of the steel industry has a direct impact on the coupling manufacturing industry.

Steel Industry Development:

For the development of the steel industry in 2011, the situation is relatively complicated. The main factor affecting the development of the steel industry is investment. In the second half of 2010, the implementation of energy conservation and emission reduction policies and policies to control the growth of newly-started projects, especially high energy-consuming projects, led to an increase in investment. Although 2011 is the first year of the "Twelfth Five-Year Plan", it is possible that investment in various regions will rebound to a certain extent, but overall, the work during the "Twelfth Five-Year Plan" period is transformation, and the keynote of the policy in 2011 is "prudent and flexible" , so the high investment growth after 2009 is unlikely to reappear; secondly, the project structure of investment growth may undergo major changes, and the trend of large-scale investment mainly in infrastructure construction since the financial crisis will undergo major changes , transformational investment represented by investment in strategic emerging industries will be highlighted; real estate investment will have uncertainties. On the one hand, housing construction will continue to be promoted by policies; With great uncertainty, it is difficult to predict the prospect of commercial housing investment.
