General technical features are obvious, multiple effects have emerged
Optimize industrial structure, improve production efficiency, and change the division of labor
In recent years, the development of artificial intelligence technology and applications has shown a new trend. Artificial intelligence has realized the transition from experimental technology to industrialization. "Deep learning + big data" has become the main technical route for the development of artificial intelligence, while artificial intelligence applications have expanded from service industry to manufacturing and agriculture. All of these have made artificial intelligence show more and more obvious general technology and basic technical characteristics, and the influence on the manufacturing industry has become increasingly prominent.
Artificial intelligence optimizes the manufacturing industry structure. On the one hand, artificial intelligence will phase out certain manufacturing sectors. Artificial intelligence replaces the functionality of certain products, and the industry in which such products belong will shrink and disappear. Some traditional mechanical equipment and related parts manufacturing in the manufacturing industry may face the risk of shrinking market. Traditional electronic information products without artificial intelligence functions will also face tremendous escalation pressure. On the other hand, artificial intelligence will revolutionize certain industries. The combination of artificial intelligence and traditional manufacturing products is reflected in the short-term to provide some new features, but will eventually completely subvert the product and industry architecture. For example, after artificial intelligence-driven driverless replacement of traditional cars, transportation systems, laws and regulations, the way cars are sold and used, and the car-centric business ecosystem will undergo revolutionary changes. In the future, intelligence will become one of the standard basic functions of most products, and almost all manufacturing products will change. At the same time, artificial intelligence and related industries will develop into new pillar industries. As a general purpose technology, artificial intelligence has huge application space in various industries and fields. As new technologies mature and market demand expands, many new technologies will eventually evolve into new industries. Artificial intelligence and related support technologies and derivative services will also develop into a large-scale industrial system.
Artificial intelligence will increase manufacturing productivity. First, artificial intelligence can improve the level of intelligent manufacturing and extend the start-up time of the factory. The use of more intelligent robots means that the factory and the workshop can achieve longer working hours. The company can start the factory 24 hours a day without paying extra overtime. The United States, Japan, Germany and other countries have already seen non-stop work. "Nobody factory." Second, artificial intelligence can promote the matching of production and demand, and improve the flexibility of the production line. By predicting market trends, artificial intelligence scientifically arranges production plans throughout the industry chain, so that each link maintains the minimum inventory, even “zero inventoryâ€, while improving the matching efficiency of demand and products. Third, artificial intelligence can improve the quality inspection level and improve the product yield. Artificial intelligence is fully monitored in real time in all aspects of the production line. Compared with the traditional method, the artificial intelligence monitoring of the production process can greatly improve the company's ability to monitor and control product quality, reduce product defect rate and improve production efficiency. Some enterprises use artificial intelligence to conduct a comprehensive quality inspection of the production process, which can increase the profits of hundreds of millions of yuan each year.
The development of artificial intelligence will change the pattern of international division of labor in manufacturing. Artificial intelligence will reshape the global manufacturing value chain and form a new international division of labor system, which will have a major impact on the traditional international division of manufacturing. On the one hand, artificial intelligence adds new links to the traditional value chain. This link has become a new commanding height in the value chain. Developed countries are trying to seize this commanding height to strengthen their manufacturing industry's dominance of global division of labor. On the other hand, artificial intelligence has also changed the traditional value chain form, and the labor cost advantage of developing countries will continue to weaken. Like other developing countries, China's manufacturing industry still has labor cost advantages in competition with developed countries, but more applications of artificial intelligence will weaken this advantage. At the same time, China's labor costs continue to rise, and labor costs have become high. The bottleneck of manufacturing development in coastal developed areas, and the application of artificial intelligence can alleviate this pressure. From this perspective, China's accelerated application of artificial intelligence in manufacturing will have a more complex impact.
It is worth noting that artificial intelligence has different effects on different industries in the manufacturing industry. For labor-intensive industries such as home appliances and consumer electronics, the role of artificial intelligence is mainly reflected in reducing the number of employees and improving product quality. For industries driven by technological innovations such as biomedicine and aerospace, artificial intelligence is in data mining. High efficiency in analysis and other aspects will change the traditional technology research and development model; for process industries such as metallurgy and chemical industry, artificial intelligence can help achieve low-cost customized production; for clothing, food and other industries, artificial intelligence can Help companies accurately predict market trends and develop rapid response capabilities.
Seize the development opportunities and enhance the competitiveness of manufacturing
Make full use of advantages, formulate development routes, and focus on key breakthroughs
First, make full use of the comprehensive advantages and implement the reverse integration strategy. China has advantages in realizing artificial intelligence application scenario optimization and commercial layout in the manufacturing process. It should make full use of these advantages to further integrate and utilize global innovation resources, especially artificial intelligence basic technology, core technology and innovative resources in key components and equipment fields. . Encourage leading manufacturing enterprises to rely on the advantages of applied technology, huge domestic market and strong capital power to strengthen R&D cooperation with leading international enterprises in core technologies and key technologies, and integrate local innovations in developed countries as much as possible. The network gradually accumulates capabilities. China's leading manufacturing enterprises should be encouraged to jointly establish artificial intelligence research and development institutions overseas, strengthen scientific and technological cooperation and information exchange, and make full use of innovative resources such as international technology, capital and talents to enhance research and development capabilities in core technologies and key technology fields.
The second is to compile a strategic (route) map of manufacturing artificial intelligence technology, and regularly revised to help the public to timely and accurately grasp the development trend of artificial intelligence technology and industry. It is necessary to pay more attention to the process of formulating the technical strategy map and judging the development trend. In this process, we must not only form a consensus on the development trend of artificial intelligence technology, but also form knowledge exchange and interaction between academic and industrial circles. Relevant parties will conduct in-depth exchanges and discussions on the development direction of artificial intelligence technology and possible breakthroughs, promote knowledge integration, expansion and deepening, and lay the foundation for technological innovation and application development.
The third is to strengthen the role of artificial intelligence in promoting the transformation and upgrading of manufacturing. In the new round of international division of labor, China needs to carefully select the key areas and directions for the development of artificial intelligence, and strive to create features and force the high-end links. It should be noted that the manufacturing industry is a country with strong international competitiveness. We should carefully grasp the investment focus of artificial intelligence and firmly grasp the strategic opportunities for the development of artificial intelligence applications in the advantageous manufacturing field. At the same time, it is also necessary to make effective efforts in the fields of image and speech recognition.
The fourth is to attach importance to social issues such as law and ethics that arise in the development of artificial intelligence. With the development of artificial intelligence, it is necessary to establish an appropriate and effective mechanism as soon as possible to accurately assess the ethical, legal and social impacts brought about by the development of artificial intelligence. Relevant institutions, such as artificial intelligence committees, should be established to oversee evolving scientific and technological practices. This body needs to include a wide range of experts, practitioners, non-government representatives, etc., while establishing clear rules to ensure transparency in the decision-making process. Build a structurally sound responsibility system.
The Tapered Roller Bearing belongs to the separation type bearing, and the inner and outer rings of the bearing have a conical raceway. This type of bearing is divided into single, double and four row tapered Roller Bearing according to the number of the roller. The single row Tapered Roller bearing can bear the radial load and the single direction axial load. When a bearing is subjected to a radial load, an axial force will be produced, so another bearing that can withstand the axial force of the opposite direction is needed to balance it.
There is a single row tapered roller bearing outer ring, the inner ring and a conical roller by maintaining a basket frame into the inner module. The outer ring can be separated from the inner ring assembly. According to the standard of the ISO tapered roller bearing dimension, any standard type tapered roller bearing outer ring or inner ring assembly should be able to achieve international interchangeability with the same type of outer ring or inner ring assembly. For example, the outer ring of the same type should conform to the ISO492 (GB307) rule besides the external dimension and tolerance. The conical angle of the inner ring assembly and the diameter of the component cone must also comply with the relevant provisions of the interchangeability.
Usually, the conical angle of the outer raceway of the single row tapered roller bearing is between 10 degrees ~19 degrees, and it can simultaneously bear the joint action of axial load and radial load. The larger the cone angle, the greater the ability to bear the axial load. The bearing of the big cone angle, the postposition code plus the B, the cone angle between 25 degrees ~29 degrees, can bear a large axial load. In addition, the single row tapered roller bearing can adjust the size of the clearance during the installation process.
The outer ring (or inner ring) of a double row tapered roller bearing is a whole. The two inner ring (or outer ring) has similar small end faces, and the middle has a spacer. The clearance is adjusted by the thickness of the spacer, and the pre interference of double row tapered roller bearings can also be adjusted by the thickness of the spacer.
The performance of the four row tapered roller bearing is basically the same as that of the double row tapered roller bearing, but the radial load of the double row tapered roller bearing is greater than that of the double row tapered roller bearing, and the limit speed is slightly lower, which is mainly used for heavy machinery.
Multi seal double, four row tapered roller bearings, ZWZ provides long life, multi seal double, four row tapered roller bearings. The new design of the bearing is personalized and the traditional design method of the fully sealed bearing is changed. A new seal structure combined with seal and dust-proof is adopted to improve the sealing effect and improve the sealing performance. Compared with open structure bearings, the life of multi seal double and four row tapered roller bearings increased by 20% to 40%, and the consumption of lubricants was reduced by 80%.
Tapered roller bearings are widely used in automobile, rolling mill, mine, metallurgy, plastic machinery and other industries.
