Long Forged Steel Double Helical Herringbone Gear Large Cudtomized Big Roller Module Shaft

Forged shafts are shaft parts made by forging. Forging is a processing method that uses pressure to cause plastic deformation of metal materials to obtain blanks or parts with certain shapes, sizes and properties. For shafts, forging can improve their internal structure and make the metal fiber streamlines along the contour of the shaft, thereby improving the strength, toughness and fatigue resistance of the shaft.

Common materials for forging shafts are carbon steel (such as 45 steel) and alloy steel (such as 40Cr). Carbon steel is relatively cheap, has certain strength and toughness, and is suitable for general-purpose shafts. Alloy steel has better comprehensive properties, such as higher strength, hardness, wear resistance and corrosion resistance, and is suitable for shafts that bear large loads and work in harsh environments, such as crankshafts of automobile engines.
Our company's forging series products include:

Industrial forgings for civil industries such as machine tool manufacturing, agricultural machinery, farm implement manufacturing and bearing industry;
Shaft segments such as main shaft and intermediate shaft for hydro-generators, forgings for thermal power plants such as rotors, impellers, and retaining ring main shafts;
Forgings for metallurgical machinery such as rolls and gear shafts; forgings for kettle ring, cylinder, cylinder, and axle forging machinery.

 

Automobile Industry
The core components of automobile engines, such as crankshafts and half shafts, mostly use forged shafts. The crankshaft is subjected to the complex stress generated by the operation of the engine. The forging process makes it have high strength and fatigue resistance, ensuring the efficient and stable operation of the engine; the half shaft is responsible for accurately transmitting power to the wheels. Forging gives it the ability to resist impact and distortion under various road conditions and driving conditions. Whether it is a sedan, SUV or heavy truck, forged shafts play a decisive role in the power transmission and driving safety of the car.

Mechanical Equipment Manufacturing
In various types of machinery such as machine tools and printing presses, forged shafts are widely used in the main shaft and transmission shaft parts. The machine tool main shaft has extremely high precision requirements. The uniform organizational structure and good mechanical properties of the forged shaft can effectively reduce the vibration during high-speed rotation and ensure the processing accuracy; the mechanical transmission shaft needs to deal with different torque and speed changes in the process of transmitting power. The forged shaft can rely on its excellent strength and toughness to reliably transmit power between components, maintain the smooth operation of the entire mechanical system, and improve production efficiency and product quality.

Aerospace Field
The compressor shaft, turbine shaft and various shaft parts in the aircraft transmission system of aircraft engines are inseparable from the forging process. The aircraft engine shaft works in an extremely harsh environment of high temperature, high pressure and high-speed rotation. The special organizational structure design of the forged shaft can greatly enhance its high temperature creep and fatigue resistance, ensuring the safety and reliability of the engine in long-term flight missions; the aircraft transmission system shaft bears heavy responsibilities in key links such as aircraft flight control and landing gear retraction and extension. The high reliability and high strength of the forged shaft provide a solid guarantee for flight safety, enabling it to adapt to the complex and changeable aerospace working conditions.

Shipbuilding Industry
Ship propulsion shaft systems, such as intermediate shafts and propeller shafts, are typical applications of forged shafts. When the ship is sailing, these shafts need to withstand huge torque, axial thrust and long-term corrosion from seawater. The forged shaft ensures sufficient strength and toughness through optimized metal fiber flow direction and good comprehensive performance. At the same time, with appropriate anti-corrosion measures, it can efficiently transmit the power of the ship's main engine to the propeller, driving the ship to sail stably in the marine environment, which is crucial for the normal operation of large ocean-going ships and various types of ships.

Power Engineering
The generator shaft is a key component in power production equipment, especially in large hydropower and thermal power generators. The generator shaft has to bear multiple loads such as the rotor's deadweight, electromagnetic force, and strong centrifugal force generated by high-speed rotation. The excellent mechanical properties of the forged shaft ensure that it will not deform or fatigue damage during long-term operation, ensuring the stable power generation of the generator, laying the foundation for the continuity and reliability of power supply, and is an indispensable element for the construction and stable operation of the power industry infrastructure.

Railway Transportation
Forged shafts are widely used in the axles of railway locomotives and various shafts in the transmission system. The axles have to bear huge weight loads, impact loads, and stress changes caused by frequent braking and starting during the high-speed driving of the train. Forged axles ensure the safety and stability of train operation with their excellent strength, toughness and fatigue resistance. At the same time, in the power transmission system of railway vehicles, such as the transmission shaft in the gearbox, forged shafts can also reliably transmit power to ensure the efficient and smooth operation of the railway transportation system. Whether it is a passenger train or a freight train, forged shafts are key supporting components.
