Gear grinding bearing of spiral bevel gears
Gear grinding bearing of spiral bevel gears We have learned, our country independent research and development of large equipment has been the restriction of the key components, especially our country automobile equipment, mining equipment, metallurgical equipment, oil equipment, building materials equipment, power generation and ship equipment in areas such as the large size and high precision spiral bevel gears have long been dependent on imports, only a few countries in the world capable of producing. Gear grinding bearing of spiral bevel gears This time through the identification and has the biggest outside the batch production of spiral bevel gear circle diameter of 1100 mm, the modulus maximum 24 mm, tooth width 190 mm, maximum bevel gear shaft positioning largest diameter is 200 mm, is currently the world's largest specifications of gear grinding spiral bevel gears. Appraisal committee believe that the success of the product, to fill the domestic blank, broke the monopoly of foreign products, effectively relieve the restricts the bottleneck of major equipment in key parts and components. The equipment processing outside diameter to 800 mm, only one of the biggest German equipment to 1000 mm, is our country after the United States, Germany, the third can produce CNC spiral bevel gear gear milling machine, grinding machine, lapping machine series of high-grade equipment. Wall to domestic YK22100 CNC spiral bevel gear milling tooth machine and gear grinding machine production products maximum diameter up to 1100 mm, and foreign equipment processing driving wheel positioning shaft can reach 100 mm diameter, wall needs up to 200 mm, the product accuracy can reach level 5 ~ 6, this is a breakthrough, is currently China's large size and high precision at home can get the biggest processing capacity of spiral bevel gears. As the large size and high precision high speed heavy users of circular arc spiral bevel gear, the Chinese heavy industry of chongqing gearbox co., LTD. Technology center, deputy director of the standing Cao Yun tells a reporter, along with the development of the economy, mining, cement, steel rolling industries such as the production line to develop, which has given rise to large reducer market in our country. Heavy tooth is one of the largest industrial heavy deceleration mechanism to build enterprise, the company in recent years, the design of vertical mill production reducer is to solve the cement grinding, power plant coal, steel slag, slag grinding powder and other special requirements of patent products. High precision, high strength, large size, hard tooth surface of spiral bevel gears is adapt to the specific requirements of the product high technology core components, but due to reasons such as foreign technology monopoly, heavy vertical mill tooth company since put into production using this widget has been dependent on imports, and resources is quite nervous. In the impression of Cao Yun, heavy gear company over the past 20 years has been looking for a supplier of large size high-grade spiral bevel gears in time. They went around the americas, Europe and Japan, with several countries products, general order cycle is long, expensive. Then choose a Nordic enterprise products, packing the maritime transport time after nearly two months, a pair of gears freight will be less than 20000 euros. Gear grinding bearing of spiral bevel gears This, he said happily, under the good, at home can get resources, components can effectively alleviate the bottleneck, the host can be greatly reduced the cost of the product, the heavy gear company's market competitiveness will be improved.
