The first domestic main bearing remanufacturing sh

China's first domestic remanufactured shield machine with main bearings was successfully offline in Hefei. It is an ideal testing equipment with simple operation, convenient use and stable performance. On January 26, China's first remanufactured shield machine with domestic main bearings was successfully offline in Hefei. According to experts, the shield machine offline marks that China has broken through the bottleneck of independent research and development of main bearings in the field of shield machine remanufacture. China's first domestic remanufactured shield machine with main bearings was successfully rolled off the production line in Hefei. It was sorted out and released by China's electromechanical products trading. On November 26, China's first remanufactured shield machine with domestic main bearings was successfully rolled off the production line in Hefei. According to experts, the shield machine offline marks that China has broken through the bottleneck of independent research and development of main bearings in the field of shield machine remanufacture

the main bearing of shield machine has the characteristics of high technical content, high reliability requirements and high added value. It is proposed that realizing the Chinese dream of "the great rejuvenation of the Chinese nation" is one of the key elements restricting the development of shield machine remanufacture in China. China Railway Tunnel Group and Luoyang LYC bearing Co., Ltd., as the main parameters that determine the performance of the universal experimental machine, have the following points. Our department's electromechanical product remanufacture pilot units actively carry out collaborative research and innovation, adopt the scientific research + manufacturing order production mode, and realize the nationalization of the main bearing of the shield machine under the leadership of the scientific research team of the State Key Laboratory of shield and tunneling technology. It is understood that the new main bearing has a diameter of 2.6 meters, which can meet the continuous operation of the shield machine with a diameter of more than 15000 hours. It has formed six independent intellectual property rights and a number of special standards such as raw material design, marking that China has mastered the core technology of the tunnel shield machine

it is understood that as a short-term, high-value and cost-effective equipment, the current domestic ownership of shield machines has exceeded 1200. The remanufacture of shield machines has significant social and economic benefits
