Super large integral bearing forgings are rolled off the line at Iraette
On July 29, 2021, the ultra-large monolithic bearing forgings with a diameter of 11.5 meters provided by Iraite for Luo Shaft successfully rolled off the production line, and passed the certification of CCS by China Classification Society and user acceptance.The forgings have broken the world record of super large integral bearing forgings.In the manufacturing industry, bearings are indispensable wherever rotation is needed, from the small parts of bicycles to the current Tiangong space station.Therefore, bearings are called "the heart of mechanical equipment", which directly determines the operation performance, service life and safety and reliability of equipment.With the continuous breakthrough of manufacturing technology in China, equipment accessories are developing towards large-scale and high-end.And bearing belongs to mechanical products, is not to take advantage of the basic parts, so the factors that affect the performance of bearing in addition to dimensional accuracy, as well as the material and processing technology used in the production process of its body.In recent years, Iraeta has been maintaining a good cooperative relationship with Luo Axis, and has carried out a number of fruitful cooperation.In the future, we will deepen cooperation, explore cooperation projects in more areas, identify areas of convergence and realize complementarity.
In the past, such large bearing forgings are mostly welded in sections, which not only has a long processing cycle and high cost, but also has weak material structure and performance at the weld position.This time, the bearing forgings provided by Iraette for the luo shaft adopted the whole rolling process. On the one hand, it can make its internal organization more compact and streamline more complete, and also make the performance potential of the metal materials get full play, so as to effectively improve the service life and mechanical properties of the workpiece;On the other hand, it can greatly shorten the delivery time and effectively assist customers to achieve early production.
At present, Iraette continues to deepen the cooperation with academician Li Yiyi team of institute of Metals, Chinese Academy of Sciences and other scientific research institutions, committed to promoting the development and application of various advanced technologies and materials.Cao Xuzhong, executive president of Iraett, said: The bottom line of the bearing forgings fills the domestic gap in the field and increases the design thinking space for designers.
