On October 14, 2015, Kunming Yunnan Yunnei Power Co., Ltd. workshop, the production line is in full swing ... In January-August, Yunnei Power accumulated sales of all types of diesel engines 137,499 units, in the context of falling sales in the industry , Yunnei still grew 6.11%.
Yunnei Advanced Technology to Build Strong Enterprise Flexibility Mechanism
In August 2014, Yunnan proposed to focus on cultivating and developing large-scale biological, large-scale energy, large-scale manufacturing, large-scale tourism, and large-scale service of five trillion yuan of "big industry." In the transformation and upgrading of industrial structure, major projects must be grasped and brought to the forefront to drive the extension of the industrial chain. As the first batch of innovative enterprises and high-tech enterprises in Yunnan Province, the strategic development of Yunnei Dynamics has become a vane indicator of Yunnan's industrial development performance.
It is hard to imagine that the current total assets of RMB 6.8 billion and the leading enterprises in the Chinese automobile engine industry have just been lost to the market in the early 80s of the last century. How does Yunnei achieve its own breakthrough? Looking back over more than 50 years of development history, Yang Yongzhong, general manager of the company, said: “To understand the current market and predict the future market, Yunnei can accurately and in advance position the market and improve the product market. Share."
In the 1990s, Yunnei Power seized the opportunity of the light-duty diesel vehicle market to trial-produce a prototype of the 4100QB diesel engine to form a fist product. Since 2006, Yunnei has begun researching DEV Series IV diesel engines. At present, D19, D20 and other products have been successfully carried on various models of many large-scale enterprises such as Beiqi Foton, Jianghuai Co., Ltd., and FAW-GM and have initially established a core market framework. After the implementation of the National IV Standard in 2015, Yunnei’s market share rapidly increased by 2%, and the installed capacity of the 22 major automobile plants increased by 10.46%.
Technological innovation is the foundation of an enterprise. Yunnei Power has built a “four-in-one†research and development base for Kunming Technology Center, Eastern Technology Center, Chengdu Gas Development Center, and Shandong Technology Center. In 2012, the D19TCI Euro V engine was successfully exported to the United Kingdom with MG6 cars, creating a new era in the export of China's own brand diesel engines to Europe.
Institutional innovation allows companies to rejuvenate. In 2014, Kunming Yunnei Dongdong Technology Center was registered in Wuxi. The establishment of the Eastern Technology Center took full advantage of the concentration of talents in the “Yangtze River Delta†region and the concentration of automobile and engine parts companies, breaking the single-system R&D structure.
In 2013, the Yunnan Provincial Party Committee and Provincial Government issued the "Opinions on Accelerating the Implementation of Innovation-Driven Development Strategies," and issued 30 policies to encourage and support technological innovation and entrepreneurship, and encourage various types of innovation entities to strengthen scientific and technological innovation.
Science and technology support the industry, innovation leads the development. By the end of 2014, Yunnan had identified 782 high-tech enterprises, selected 284 innovative pilot companies, promoted the establishment of a number of strategic alliances for industrial technology innovation, and selected 48 pilot provincial-level coalitions.
Their rollers and the outer wheels are arranged in a right angle intersecting intersecting. They can bear the load from all directions at the same time (such as axial, thrust or momentum hormones, etc.). Because of the linear contact between the roller and the track surface, the possibility of the axis to bear the load and the elastic deformation is very small. This type of bearing is widely used in industrial robots, working machines and medical facilities. It needs high rigidity, high speed and high speed to ensure precise occasions.
In cross roller bearings, cylindrical rollers are perpendicular to each other through spacer retainers on the top, so 1 cross roller bearings can bear all loads of radial load, axial load and torque load. Ring size is the minimum limit of miniaturization, especially very thin type is small size close to the limit, and has high rigidity, so the most suitable for use in industrial robot joint or rotating parts, machining center machine rotary table, hand rotating parts, precision rotary table, medical machine, metering device, IC manufacturing equipment etc.
1. Excellent rotation accuracy
The inner structure of the Cross Roller Bearing is arranged in 90 degrees perpendicular to each other by the roller.
The roller is equipped with a spacer or isolation block between the rollers to prevent the rolling of the rollers from being examined each other. In addition, the phenomenon of roller contact or locking will not occur. At the same time, because the inner and outer ring is a segmented structure, the clearance can be adjusted, even if the preload is applied, high accuracy rotation motion can also be achieved.
2. Simplification of operation and installation
The outer ring or inner ring, which is divided into 2 parts, is fixed together after loading the roller and the holder, so the operation is very simple.
3. Bear large axial and radial load
The roller is arranged vertically through the spacer retainer on a 90 degree V groove rolling surface.
4. Greatly save the installation space
The size of the inner and outer ring cross Roller Bearing is miniature minimal, especially ultra-thin structure is small size close to the limit, and has high rigidity, so the most suitable for industrial robot joints or rotating parts, machining center of the rotary table, the robot rotating parts, precision rotary table, medical instrument IC, measuring equipment, manufacturing device widely used.
5. high speed ability
6. reducing shaft length and machining cost, thermal expansion leads to a limited change in geometric size.
7. the nylon separator is used, the moment of inertia is low, the starting torque is low, and the angle degree is easy to control.
8. optimization of pretightening force, large rigidity, high precision of guiding roller
9. carbon steel provides excellent impact resistance and surface abrasion resistance
10. simple but fully lubricated
