With the continuous progress of China's reform and opening up, world-class multinational companies have begun to enter the Chinese market in large numbers, producing gears and gear devices for automobiles, engineering machinery, and large complete sets of equipment in China.
The development of reducer and gear technology has broad prospects in China and internationally, with the overall trend moving towards "six highs, two lows, and two transformations": high load-bearing capacity, high precision, high speed, high reliability, high transmission efficiency, low noise, low cost, standardization, and diversification.
1. Current Situation of Domestic Reducer Development
Since the 1960s, China has successively formulated a batch of general reducer standards, such as the "Cylindrical Gear Reducer" standard of the First Ministry of Machinery Industry of the People's Republic of China. Most of the reducers in the 1960s were manufactured based on the technology of the 1940s to 1950s in the former Soviet Union. Although there has been some development since then, the overall level still lags behind the international level.Since the reform and opening up, China has successively formulated standards for nearly 100 gears and worm gear reducers and introduced a batch of advanced processing equipment. Many products have reached the international level of the 1980s. In the mid to late 1990s, China successively launched updated reducers, which not only highlighted the characteristics of modular design but also significantly improved the load-bearing capacity, overall level, and appearance quality.
2. Current Situation of Foreign Reducer Development
Foreign reducers, especially those from Germany, Denmark, and Japan, are in a leading position, particularly in terms of materials and manufacturing processes. The reducers have good reliability and long service life. In the 1970s and 1980s, there was significant development in reducer technology worldwide, closely linked with the development of new technological revolutions. Foreign reducers today are developing towards high power, high transmission ratio, small size, high mechanical efficiency, and long service life.Therefore, in addition to continuously improving material quality and enhancing process levels, there is also in-depth exploration and innovation in transmission principles and structures, with the emergence of principles such as the planetary gear transmission. The integrated structure of reducers and motors is also a vigorously developing direction, and various structural and power models have been successfully produced.
3. Development Trends of Reducers
Reducer technology has stood the test of time and become one of the mature technologies in the world today. The development of its design and manufacturing technology to a certain extent symbolizes a country's industrial technological level.Therefore, the development and exploration of reducer and gear technology have broad prospects in China. With the continuous progress of China's reform and opening up, world-class multinational companies have begun to enter the Chinese market in large numbers, producing gears and gear devices for automobiles, engineering machinery, and large complete sets of equipment in China.
There will be a large number of international brands joining the gear products in China, which will inevitably lead to a major adjustment in the structure of Chinese components, and the specialization and concentration of gear production will continue to increase.
In short, not only in China, but also internationally, the overall trend of reducer and gear technology development is moving towards "six highs, two lows, and two transformations": "six highs" meaning high load-bearing capacity, high tooth surface hardness, high precision, high speed, high reliability, and high transmission efficiency; "two lows" meaning low noise and low cost; "two transformations" meaning standardization and diversification.
