The Ultimate Guide to Forged Shafts
In the modern manufacturing industry, shaft parts are core components for power transmission. They silently bear enormous torque and loads while always outputting power stably, and are undoubtedly key and important parts in many mechanical equipment. So, what is a forged shaft? What unique features does it have? And in which fields is it used? This article will comprehensively explore the performance characteristics, applications, processes, materials and other information of forged shafts supplied by Songjie, providing guarantee for your projects.
I. What is a Forged Shaft?
A forged shaft is a type of shaft component with specific shape, size, and mechanical properties, produced through forging processes (hot forging, cold forging, or warm forging). In machinery, all parts that perform rotational motion are mounted on shafts. Forged shafts are typically used to support rotating components and rotate alongside them, thereby transmitting motion, torque, or bending moment.
II. Characteristics and Performance of Forged Shafts
- Coexistence of high strength and excellent toughness
- Strong load-bearing capacity and good wear resistance
- Precise dimensional control with minimal subsequent machining allowance
- Uniform internal structure and high stability
- Excellent heat treatment response and fatigue resistance
- High reliability and long service life
- High temperature resistance and strong adaptability
- Strong customizability and high material utilization rate
III. Applications of Forged Shafts
Thanks to the performance and functions of forged shaft components, they are widely used in various industries, often including automotive, machinery, energy, shipbuilding, aerospace, and so on.
In these fields, forged shafts are typically applied in scenarios such as gear shafts in automotive transmissions, machine tool spindles, steam turbine spindles, engine crankshafts, turbine shafts, rotor shafts of steam turbines, and hydraulic systems.
IV. Forging Shaft Processes
(1) Forging Process: Generally, our forged shafts can be produced using different forging methods such as free forging and die forging according to customers’ varying requirements. The heated billet is subjected to pressure to be forged into the required shape and size. Free forging offers high flexibility and is suitable for single-piece and small-batch production; die forging, on the other hand, is applicable to mass production and shafts with complex shapes, enabling more precise shaping.
(2) Heat Treatment Process: To further improve the mechanical properties of the shaft and eliminate internal stresses generated during the forging process, heat treatment is required. Processes such as normalizing, annealing, quenching, and tempering are adopted to optimize performance and structure.
(3) Machining: For forged shafts, we can perform machining operations like turning, milling, and grinding to meet the final requirements for dimensional accuracy and surface roughness.
(4) Surface Treatment Process: We provide treatments such as shot peening, plating, and spraying to enhance corrosion resistance and wear resistance.
