Commonly materials include: 20CrMnTi, 45#, 40Cr, 20CrMo, 42CrMo, CuSn12, CuAl10Fe3.Cutting, Forging, or Casting:The preparation of materials for ordinary-sized gears is done by cutting cylindrical raw materials with an electric saw. For large-sized (diameters of 2m, 1.8m, 0.8m, etc.) or high-strength requirement gears, forging is commonly used for initial shaping; for more complex-shaped gears, casting processes of Metallurgy Powder may be employed.Termal Refined:Quenching: Gears are first heated to a certain temperature and held for a period to ensure uniform temperature throughout the workpiece. They are then rapidly cooled, usually using oil, water, or air as cooling mediums, significantly increasing hardness and strength.High-Temperature Tempering:Post-quenching, gears become very brittle and are not suitable for direct use. Thus, they undergo high-temperature tempering, being reheated to temperatures typically between 500-650°C, held for a period, and then slowly cooled. This step reduces internal stresses, improves brittleness, and adjusts the material's hardness and toughness, achieving optimal comprehensive mechanical properties.Rough Machining (Initial Processing):In the initial machining phase, the gear blank undergoes a series of mechanical processing methods, including turning and milling, which meticulously shape the raw material closer to its final design specifications. During this crucial step, not only is any excess material carefully removed to minimize waste and reduce the workpiece to near its intended size, but the fundamental outline and basic features of the gear are also precisely established. Heat Treatment:To enhance the gear's hardness and wear resistance, heat treatments such as carburizing quenching, high-frequency quenching, etc., are usually performed. The heat treatment process can significantly improve the gear's mechanical properties. Carburizing involves heating the gear to a high temperature in the presence of a carbon-rich environment, allowing carbon atoms to diffuse into the surface layer of the metal, thereby increasing its carbon content. This process is followed by rapid cooling, or quenching, typically in oil or another suitable medium, which hardens the surface while keeping the core relatively softer and more ductile. This combination enhances the gear's durability and extends its operational life under high-load conditions.High-frequency Qunching, utilizes induction heating to target specific areas of the gear with high-frequency electrical currents. This method heats the surface layer quickly and uniformly, achieving deep and consistent hardening without affecting the material's core properties. It is particularly effective for enhancing wear resistance and fatigue strength in localized regions of the gear that experience the most stress during operation.Precision Machining:After heat treatment, gears undergo further precision processing. These accuracy grades are critical in determining the gear's performance and suitability for various applications.The final stages of precision processing, therefore, play a pivotal role in achieving the desired accuracy grade, ensuring that each gear performs optimally within its intended application. By meticulously controlling factors like tooth profile, pitch, runout, and surface roughness, manufacturers can produce gears that not only meet but exceed the necessary standards for performance and reliability.Inspection:Testing and Quality Control encompass comprehensive evaluation and assurance processes for both semi-finished and finished gear products. This includes not only routine visual inspections and dimensional accuracy checks but also critical assessments post-heat treatment, such as surface hardness testing, core hardness testing, and microstructure analysis. These evaluations are essential to verify the material properties and structural integrity of the gears, ensuring they meet stringent performance criteria.Spec.

The gears will be wrapped in rust proof paper or a film coated with rust proof oil to prevent corrosion. Afterwards, place it in a sturdy cardboard or wooden box and fill it with cushioning material to reduce the impact of vibration and collision. For particularly large or heavy gears, metal frames or trays may be used to reinforce the packaging.The importance of safe packaging lies in its ability to ensure that gears remain intact during transportation and storage. Good packaging can effectively prevent gears from being physically damaged, corroded, and affected by environmental factors such as moisture and dust, thereby ensuring that the quality and performance of gears are not compromised. In addition, appropriate packaging can simplify the logistics process, improve handling efficiency, and reduce overall costs. Therefore, safe packaging is a key step in ensuring the satisfaction of end users with the product.Sample delivery usually by Courier, Small Order by Air, Most shipment by Sea.Company ProfileSince its establishment, EnDao Industry and its cooperative factories have accumulated over 20 years of professional experience.
