LTZC provides an 8-meter segmented gear ring for Wuhan.

In the advancement of national key projects, every critical link is crucial to the final achievement and breakthrough. Among them, the 8-meter high-precision segmented gear ring provided by Luoyang Special Heavy Bearing Co., Ltd. (LTZC) for Wuhan Heavy Industry, applied to the vertical friction stir welding system, has become a key force promoting the project's progress, demonstrating its excellent manufacturing capabilities.

Technical Highlights of the Project:

High-Precision Gear Ring Supporting the Core Operation of the Welding System

1. High-Precision Manufacturing

LTZC's 8-meter high-precision segmented gear ring achieves top-level industry accuracy. During processing, advanced CNC machining equipment and technologies are used to strictly control dimensional tolerances, ensuring key indicators such as tooth profile accuracy and pitch circle accuracy meet design requirements. Its precision is controlled within an extremely small range. Compared with ordinary gear rings, it can effectively reduce vibration and noise during transmission, improve the stability of equipment operation, and provide a solid foundation for the high-precision operation of the welding system. For example, the control of pitch cumulative error reaches the micron level, far exceeding the standards of similar products.

2. Segmented Design and Technology 

Aiming at the super-large size of 8 meters, an innovative segmented design is adopted. The gear ring is divided into multiple parts for manufacturing, and then assembled through a special splicing process. This design not only solves the challenges of processing and transportation for large gear rings but also uses high-precision positioning and welding technologies during splicing to ensure the strength and accuracy of the splicing points, making the overall performance equivalent to or even superior to that of integrally formed gear rings. The splicing process has undergone multiple tests and optimizations to ensure that the spliced gear ring will not loosen or deform under high-speed operation and complex loads.

3. Material Selection and Treatment

High-quality special steel is selected as the gear ring material, which has high strength, high wear resistance, and good toughness. Before material processing, strict pretreatment is carried out to remove impurities and internal stress, improving material stability. After processing, the gear ring undergoes surface hardening treatment and precision grinding to further enhance the tooth surface hardness and finish, extending the service life of the gear ring and adapting to the long-term, high-intensity working environment of the welding system.

Demonstration of LTZC's Manufacturing Strength

Providing key components for Wuhan Heavy Industry this time fully demonstrates LTZC's strong strength in the field of large-scale and high-precision component manufacturing. From design and R&D to production and manufacturing, and then to quality inspection, LTZC has a complete and mature process flow and technical system, which can meet customers' customized needs for complex components. This not only enhances LTZC's popularity and reputation in the industry but also lays a solid foundation for it to further expand high-end markets and participate in more national key projects.
