The "Hardcore" Role of Mechanical Shaft Forgings in the Mechanical Field
In the field of mechanical manufacturing, various equipment and components are of vital importance. Among them, mechanical shaft forgings, like the “skeletal joints” of the human body, silently support the stable operation of various types of equipment and occupy a core position. So, what are the specific applications of these shaft forgings in the mechanical field? And what unique advantages do they possess? Next, we will delve into the specific applications and advantages of the mechanical shafts supplied by Songjie when adopted by customers.
I. Heavy Machinery and Equipment
In heavy-duty equipment such as excavators, cranes, and concrete pump trucks, mechanical shaft forgings serve as the core components for transmitting power and bearing loads. Boasting advantages of high strength, high toughness, and lightweight, they become the key to supporting the stable operation of the equipment, ensuring the durability of the equipment, and enhancing the overall mechanical performance and work efficiency.
1.1 Slewing Bearing Shaft of Excavator
This type of mechanical shaft forging is the core transmission component that connects the upper body and lower chassis of an excavator. It supports the weight of the upper body and enables 360° rotation to adjust the working direction, serving as a key component for the excavator to achieve flexible steering and bear operational loads.
Moreover, our slewing bearing shaft is endowed with high strength, fatigue resistance, and wear resistance through forging processes (multi-directional die forging forming). This allows it to work stably for a long time under complex and variable heavy-load working conditions, easily coping with the huge loads and frequent impacts during excavator operations. It acts as a core guarantee for heavy-duty excavators to achieve efficient and safe operations while extending their service life.
1.2 Drive Axle Half-Shaft of Loader
This shaft is a critical transmission component connecting the drive axle differential and the wheels, responsible for transmitting powerful torque. Any failure such as breakage could lead to catastrophic consequences. Its primary functions are to transfer power from the engine to the wheels, while simultaneously bearing the weight of the vehicle body and the impact loads during operation.
At Songjie, we typically produce this forging using forging processes (mainly die forging or open die forging). This enables the shaft forging to possess excellent strength (high torque transmission capacity), fatigue resistance, and toughness, allowing it to stably transmit torque and ensure the normal operation of the loader. It can be said that without mechanical shaft forgings, many large-scale construction machinery would be like losing their “backbone” and would be completely unable to accomplish those high-difficulty operational tasks.
1.3 Boom Shaft of Excavator
Generally, our customers require that the customized boom shafts be made of high-strength alloy steel materials to meet the demands for high strength, high reliability, high wear resistance, and impact resistance. This shaft is a key hinge shaft connecting the boom and the turntable, supporting the self-weight of the boom and the huge loads during operation, while providing a rotating fulcrum for the pitching movement of the boom.
In excavator equipment, such mechanical shaft forgings can withstand large loads and impact forces, feature high dimensional stability, and are compatible with high-precision articulation, ensuring the flexibility and stability of the boom during operation.
II. Machine Tool Equipment
Machine tool equipment has extremely high requirements for the precision of components, which must possess extremely high strength, rotational accuracy, and shock resistance, among other properties. In this regard, mechanical shaft forgings can be described as the “king of precision,” playing a crucial role and thus becoming the preferred choice for various machine tools (especially heavy-duty machine tools and precision machine tools).
2.1 Spindle of CNC Lathe
The spindle of a lathe is used to transmit power, support and drive the rotation of workpieces or tools, and directly affects the precision, stability, and surface quality of machined parts.
At Songjie, we manufacture mechanical shaft forgings through precision forging combined with ion nitriding technology, which enables excellent control over dimensional accuracy and form accuracy. This ensures the stability of the CNC lathe spindle during high-speed rotation, reduces vibration and runout, and thus allows the machined parts to meet higher precision standards.
2.2 Transmission Shaft of Machine Tool
The transmission shaft of a machine tool is mainly used to connect different components and transmit power in the machine tool’s gearbox and feed system, ensuring the stable operation of the machine tool.
This mechanical shaft forging is capable of bearing torque and a certain radial load, and boasts advantages such as high strength, high precision, high surface quality, and high material utilization rate. It ensures the long-term stable operation of machine tool equipment and significantly extends its service life.
Conclusion
Beyond the above, the specific applications of the mechanical shaft forgings procured by our customers also include the worktable drive shaft of milling machines, transmission gear shafts in gearboxes, crankshafts of presses, gear shafts, press crankshafts, gearbox output shafts, etc. All these play important roles in improving the quality and efficiency of mechanical processing. Moreover, at Songjie, our shaft forgings are also highly favored in multiple application scenarios within the automotive sector, providing high-quality material guarantees for various fields and standing as irreplaceable core forgings.
