Executive Vice President of the All-China Federation of Industry and Commerce, Hardware Association of Shenyang Federation of Industry and Commerce, Chairman of Shenyang Oriental Tianhe Hardware & Electrical Equipment Co., Ltd. Lu Shijia recently wrote an article in the Industrial and Commercial Times about how to speed up the development of hardware and electromechanical industry and equipment manufacturing industry Docking, the full text is as follows:
Of the 1.2 billion people in China, there is a relative shortage of per capita resources, which is not half or even 1/3 of the world average. The rapid economic growth is at the expense of waste of resources, energy waste, and environmental pollution. It is an extensive economic growth model. Among them, the hardware and electrical machinery industry and manufacturing industry are the most important, and they are based on a large amount of manpower, material resources, and financial resources. This is also one of the reasons why China's hardware, machinery and electronic products frequently encounter foreign trade barriers. The development of China's hardware industry needs and the practical experience of the developed country industry in the development of dovetail service, change the status of China's hardware industry to achieve sustainable economic development and the construction of a conservation-oriented society, you need to actively integrate industry resources and accelerate the hardware and electronic machinery industry. Docking of equipment manufacturing industry, integration of hardware industry chain.
Hardware is a metal product used in production and life. Gold, silver, copper, iron, aluminum, tin and other products are called hardware products. Hardware company operating product points: architectural hardware, daily hardware, decorative hardware, hardware tools, fire equipment, sundries and so on. Electromechanical products include tools, machine tool equipment, general equipment, instruments, electrical appliances, mining equipment, power transmission and power station equipment, pneumatic and hydraulic components, automated engineering control transmissions, and so on.
Equipment manufacturing industry is a manufacturing industry that provides production and technical equipment for national economy and national defense construction; it is the foundation of manufacturing industry and the foundation of other industries. It will determine a country’s economic strength, national defense strength, comprehensive national strength, and global economy. Competition and cooperation.
In the developed countries' equipment manufacturing industry, the United States accounted for 37.5% of the total GNP, leading by aircraft and integrated circuits; Japan accounted for 38.8%, mainly electrical machinery; Germany accounted for 40.9%, mainly transport machinery; It accounted for 31.8%, mainly for aircraft shipbuilding; China accounted for 12.7% of the medium- and low-end equipment. How to speed up the connection between the hardware, machinery and electronics industries and the equipment manufacturing industry, personally think that the following aspects should be strengthened:
1. Cultivate and build a group of large enterprise groups with strong international competitiveness. Break down industry, regional and ownership boundaries, key regions, key industries, key enterprises, and key products to achieve independent innovation. According to the characteristics of the product and process of the industry to implement strategic restructuring.
2. Capital-linked, market-oriented, building a conservation-oriented national economic system and achieving scale operations. We need to work hard to reduce costs in accordance with the requirements of both internal and external requirements. The rate of autonomy of parts and components must be changed to be large, comprehensive, small, and all-round, and the full play of existing production capabilities. In order to form a economies of scale, market-oriented product structure and strategic adjustment of the machinery industry will be promoted, and the obsolete technology, waste of resources, and severely polluted processes will be resolutely eliminated. U.S. investment in technological transformation accounts for 69% of fixed asset investment, while in China, it is only 25%. In 25%, it is used to protect large-scale and outgrowth, accounting for 35%, and investment in installation engineering accounts for 44%. It is actually used to update technology. Only 8.3% of the equipment, which is 10,000 yuan in technological transformation funds used to update equipment is only 205 yuan.
3. Establish a batch of supporting enterprises and logistics enterprises with strong professional cooperation capabilities and build a group of specialized small-scale enterprises to form the coordinated development pattern of large, medium and small-sized machinery industries. To strengthen the independent development and technological innovation in an important position, so that enterprises become the real subject of technological development and technological innovation. "Made in China" has been changed to "Created in China". At the same time, it has increased R&D centers to develop one generation and one generation.
4. The key development market has large capacity, high technology content, long industrial chain, and obvious driving role. It has strategic areas such as software industry, e-commerce, digital products, new displays, microelectronics, optoelectronic materials, and nano-industry digital systems. equipment.
5. Transform the traditional production materials market with new formats, especially the hardware and electrical machinery market. Upgrading modernization is a general trend. In the face of competition and challenges after China's accession to the WTO, and opening up new space for development, the key lies in the comprehensive transformation and innovation of corporate systems, market management, market players, and market reputation.
The current domestic market presents a pattern of low-end melee and high-end fall. The law of market competition is from price war to technical warfare, talent warfare, brand warfare, and finally service warfare. How to regulate the market, upgrade the market, promote the domestic and international well-known brands, re-plan the layout of the hardware and electrical machinery business network and domestic and international famous brands, and re-establish a large-scale, reputable, powerful, and interdependent economic complex. Improve the overall management level and upgrade the market. Expansion of the chain to form a network of standardized management, change a single trading relationship extends to the agency system, chain system, e-commerce, the implementation of brand strategy, set quality, display, price, technology, logistics and other multi-functional integrated services in one, make full use of Advanced management systems such as informatization and e-commerce are in line with modern internationalization. The circulation service not only has commodity nature, it is not only a special form of the transfer value of the commodity to realize its value, but also has the productivity, which can generate doubled value and effect. Further, the circulation service has a certain sense of capitality, so the hardware and electromechanical supermarket should indicate that Greater capital efficiency.
As an emerging logistics model, industrial products supermarkets currently have no experience to learn from, and they need constant improvement and development. They need the support and love of the government. They also need the cooperation and support of new and old friends.

Roller bearing, one of the two members of the class of rolling, or so-called antifriction, bearings (the other member of the class is the Ball Bearing). Like a ball bearing, a roller bearing has two grooved tracks, or races, but the balls are replaced by rollers. The rollers may be cylinders or truncated cones. Only radial loads (i.e., loads perpendicular to the axis of rotation) can be carried when the rollers are cylindrical, but with conical rollers both radial and thrust, or axial, loads (i.e., ones parallel to the axis of rotation) can be carried. A needle bearing has cylindrical rollers that are relatively slender and completely fill the space between the races; in many cases the inner race is dispensed with. Because there is line contact between a roller and the races, while in a ball bearing there is point contact, in a given space a roller bearing can carry a greater radial load than a ball bearing.
Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing. They are usually located at the ends of the turbine and compressor shafts and are often mounted in a housing, but separated from it by a layer of pressurized oil known as a squeeze film damper.
In many cases, instead of having a separate inner race for roller bearings, the [inner race" is an integral part of the shaft or stub shaft. This reduces complexity, weight, and build-up of concentricity tolerances. Overall, this is cost effective, but the cost of replacement or repair is likely to be higher than for separate inner races.
