Introduction
Chain is a type of mechanical device mainly used to transmit and convert power and motion. As an important component of modern machinery, chain technology has been widely used in automobiles, elevators, cranes, ships, bicycles, large machinery and other industries, and has become an indispensible component in modern machinery manufacturing project. In this article, we will focus on the analysis and discussion of the development of modern traction chain technology.
History and Development of T raction Chain
The first chain transmission device appeared in the 12th century. Before the development of modern industrial technology, chain was mainly used in religious places for its decorative effect with language such as the chain of faith. Starting in the 16th century, various chain transmissions began to appear in agricultural production, used for stirrup and crane lifting mechanisms. In the 19th century, chain was adapted for use in modern transportation and mechanical industry, primarily to drive and power machine parts.
With the constant upgrade of productive forces, the traction chain is constantly updated and improved to meet the needs of industrial modernization. By the mid-19th century, extra-large traction chain was developed, allowing precise transmission of power and motion. During this period, the chain transmission rate was improved and the chain transmission device was miniaturized. In aviation, bicycle and other industries, the chain transmission device is becoming more and more widely used, which makes the traction chain technology and research increasingly valued, and has promoted the improvement and reform of the technology of modern traction chain.
Modern traction chain technology
Modern traction technology is dedicated to the development of high-efficiency and high-precision chain transmission technology. The development of new transmission materials and the basic research on the structure of chain have improved the smoothness and accuracy of transmission, and compensated for the defects of traditional transmission technology. According to different application requirements and types, traction chain technology can be divided into flexible traction chain, rigid traction chain and skeleton traction chain.
The flexible traction chain is suitable for small power transmission at low speed, and is composed of antifriction pins, pins, bushings and side plates. The structure of this type of traction chain is flexible, and the applied tension force is moderate, which allows for a wide range of applications. The rigid traction chain is designed for large load operation at low speed. The structure of this type of traction chain is rigid, which is suitable for sites with frequent start and stop, high speed and high load. The skeleton traction chain is a general name for transmission chains with different shapes and sizes of open steel shell, which can run stably, possibly with a small problem such as breakage.
Advantages and Disadvantages of Traction Chain
The biggest advantage of using the traction chain is its high efficiency, large power, high speed, smoothness and reliability for continuous transmission. The traction chain possesses some unique advantages, such as being able to transmit power in both directions, which is a characteristic which metals, plastics and rubber parts do not possess. In addition, it has a long service life and low production costs, which make the traction chain very popular as a power transmission device.
But the traction chain still has its limitations, such as the need to consider the choice of size to maintain the speed, and the tension of the traction chain and the need to install mechanical devices to maintain the tension. In addition, due to the flexibility of the chain, the operation is slightly more complicated, resulting in higher requirements on the operators in the process of using the traction chain.
Conclusion
The traction chain has become an important force for transmission and conversion of power and motion in modern mechanical industry, playing an important role in large machinery and other industries. The continuous upgrade of traction chain technology has made it more efficient, precise, accurate and reliable. In the future, traction chain technology will further improve and introduce more complete intelligent control and products, which is worth looking forward to.
