High-Precision Helical Gear Customization for 270L Internal Mixers

Overview:

Internal mixers operate under immense pressure and intermittent shock loads. For this project, we manufactured a set of helical gears for a 270L internal mixer, with a total quantity of 12 units, focusing on extending service life and ensuring stable power transmission through advanced material selection, precision hobbing, and carburizing & grinding processes.

Technical Specifications:

  • Gear Type: Helical Gear (Designed for smoother engagement and higher load capacity)

  • Module: M8, M9, M12 (Multi-module design to adapt to different transmission requirements)

  • Material:20CrMnTi (High-quality alloy steel with excellent carburizing performance and mechanical properties)

  • Quantity: 12 Units

  • Processing: Precision Gear Hobbing (Ensuring accurate tooth profile and stable gear meshing)

  • Heat Treatment: Quenching & Tempering (Guaranteeing excellent core toughness and overall structural stability)

  • Tooth Surface Treatment: Carburizing & Gear Grinding (Achieving high surface hardness and precise tooth contact)

  • Accuracy Class: DIN 7 (Master-level precision for high-speed, heavy-load stability)

The Engineering Advantage:

  • Superior Material Strength: By using 20CrMnTi alloy steel, combined with carburizing treatment, these gears possess excellent wear resistance and fatigue strength, fully adapting to the rigorous working cycles of internal mixers.

  • DIN 7 Grinding Precision: Our state-of-the-art gear grinding technology ensures DIN 7 accuracy, which significantly minimizes vibration, reduces heat generation, and prevents premature gear failure.

  • Optimized Heat Treatment & Tooth Surface Process: Quenching & tempering treatment ensures the gear core toughness, while carburizing & grinding enhances the tooth surface hardness, forming a perfect combination of toughness and wear resistance to cope with the high-pressure and impact environment of internal mixers.

Result:

These 12 custom helical gears provided the client with a reliable power transmission solution, significantly improving the operational stability and service life of their 270L internal mixer, and reducing maintenance costs and downtime caused by gear failure.
