The "Development and Research of Large-scale, High-precision, High-speed and Heavy-Duty Arc Cone Gears" undertaken by Zhuzhou Wold Special Gear Co., Ltd. has passed the scientific and technological achievements appraisal organized by the Science and Technology Department of Hunan Province. Talking about this result, as an expert enjoying special allowance from the State Council, Wang Shengtang, deputy chairman and secretary general of the Gear Professional Association, was very excited about his heart and said to reporters in a row that this was a major breakthrough in the field of basic equipment for China’s major equipment. It once again broke the foreign monopoly on China’s technology.
It is understood that the independent research and development of large-scale equipment in China has always been constrained by key components, especially large-scale high-precision spiral cones that are needed in China's automobile equipment, mining equipment, metallurgical equipment, petroleum equipment, building materials equipment, power generation and shipbuilding equipment and other fields. Gears have long relied on imports, and only a few countries in the world can produce them. The maximum diameter of the spiral bevel gear passed through the appraisal and mass production has reached 1100mm, the maximum modulus is 24mm, the maximum tooth width is 190mm, and the maximum positioning diameter of the bevel gear shaft is 200mm. It is the largest size grinder in the world. Spiral bevel gears. The appraisal committee believes that the successful development of this product has filled the domestic gap, broke the monopoly of foreign products, and effectively relieved the bottlenecks of key parts and components in major equipment areas.
Zeng Yong, a professor at Central South University, is a well-known gear expert in China. He is familiar with the production capacity of large-size, high-precision, high-speed and heavy-duty spiral bevel gears in the world. He said that the maximum diameter of the outer diameter of the US equipment processing is only 800mm, and the German equipment has reached 1000mm. After China is the United States and Germany, the third can produce CNC spiral bevel gear milling machines, gear grinding machines, and grinding machines. The country of the equipment. The maximum outer diameter of the product manufactured by Volvo using the domestically produced YK22100 spiral bevel gear milling machine and gear grinding machine has reached 1100mm, and the diameter of the positioning shaft of the drive shaft of foreign equipment can only reach 100mm, Wald has reached 200mm, The product accuracy can reach 5-6 grades. This is a major breakthrough, and it is also the largest processing capability of China's large-size spiral bevel gears that can be obtained at home.
As a user of large-scale, high-precision, high-speed and heavy-duty arc bevel gears, Cao Yun, deputy director of technical center of CSSC Chongqing Gearbox Co., Ltd., told reporters that with the development of economy, mining, cement, steel rolling and other industries The bigger and bigger the production line has given birth to the large-scale reducer market in China. Heavy gear is one of the largest industrial heavy-duty reducer manufacturers in China. The company's vertical mill decelerator designed and manufactured in recent years is a patented product that solves special requirements such as cement milling, power plant grinding, and steel slag slag grinding. High-precision, high-strength, large-size, hard-toothed spiral bevel gears are high-tech core parts that meet the specific requirements of this product, but due to foreign technology monopoly and other reasons, heavy tooth company vertical mill has been used since the production of this part Has been dependent on imports, and resources are very tight. In the impression of Cao Yun, Heavy Gear has been rushing to find a supplier of large-scale high-grade spiral bevel gears for nearly 20 years. They traveled throughout the Americas, Europe, and Japan, used products from several countries, had long lead times, and were expensive. Afterwards, the products of a Nordic company were selected. The shipping time after packing was nearly two months, and the shipping cost for a pair of gears was 20,000 Euros. He was pleased to say that this is a good idea. Resources can be obtained at home, bottlenecks in parts can be effectively mitigated, the cost of mainframe products can be greatly reduced, and the market competitiveness of heavy tooth companies will also increase.
While experts and users affirmed the great significance of this achievement, they also praised Zhuzhou Walled Special Gear Co., Ltd., which was established less than two years ago, for achieving such a performance. He Zongjian, vice chairman of Zhuzhou Wold Special Gear Co., Ltd., told the reporter that the company's name “Wald†is a transliteration of the English “worldâ€. It clearly shows the ambitious goal of “to be a world-class companyâ€; at the same time, “ "Wo" means "I" and "I" means "you". I hope that the company can develop harmoniously with its users and its peers. Waldell positioned its business operations as the development, design, production, sales, and technical consulting services of special gears. In the first phase, it invested 15 million yuan and built a complete CNC high-precision spiral bevel gear production line with a diameter of 1100 mm. The company adopts innovative ways of production, learning, research, and use, and forms an alliance of innovation with key users and equipment manufacturing companies such as Central South University and Heavy Gear Company, from the aspects of design and development, equipment manufacturing, product processing, and use effects. One-stop joint research, so that the domestic production of heavy spiral bevel gear in the specifications, quality, quantity, a rapid breakthrough. For example, in the development of 1100mm gear, the company boldly broke the theoretical constraint of the two spiral bevel gears, and on the basis of not changing the installation size and ensuring the strength of the original gear, the tooth system will be made from the traditional circular arc shrink tooth system or cycloid. The tooth is replaced by a circular arc height tooth, and boldly innovates in the gear specification and processing technology, so that the geometric accuracy of the product has reached 5-6, the production cycle has been shortened from the original 16 months to 3 months, and the world has been realized. Breakthrough in sex.
On April 15th this year, Volvo Corporation sent the first batch of large spiral bevel gear products to Chongqing. After being inspected by Chongqing Gearbox Co., Ltd., all performance indicators were all qualified and could completely replace imports. They quickly signed with heavy gear. More than 800 million supply contracts. In addition to heavy teeth, Volvo's products are now in line with the main reducer used in the petroleum, building materials, power, mining, steel and other industries. The monthly output has exceeded 20 sets. Around Voldor's production of special gears, some social resources take the initiative to serve them. Waldder also actively outsources the heat treatment and other processes to professional companies, allowing them to obtain greater production capacity with little or no investment. . He Zongjian said that this clustered and professional development model enabled Wal-Mart to win more time and manpower and material resources to focus on the innovation of key technologies and the enhancement of core capabilities. Based on the processing capability of the 1100mm heavy-duty spiral bevel gear, the company plans to build a high-precision spiral cone wheel production line with a diameter of 1600mm. After the completion of the project, the company will become the largest hard-surface high-precision large-scale spiral bevel gear professional production company in China and even in the world.
