Product Description
Enhance the reliability and torque transmission of your heavy industrial machinery with our premium Cement Rotary Kiln Girth Gear. Also known as a Split Ring Gear or Segmented Girth Gear, this critical transmission component is engineered for extreme durability in high-load environments.
Manufactured by Luoyang Yile Machinery, our girth gears are precision-cast and machined to meet the rigorous demands of cement plants, mining operations, and chemical processing facilities. Whether you require a replacement half-ring gear for an existing rotary kiln or a custom-designed large diameter bull gear for a new ball mill, we deliver OEM-quality solutions tailored to your technical drawings.
Heavy-Duty Construction: Cast from high-grade Carbon Steel (ZG45) or Alloy Steel (42CrMo) to withstand massive torque and continuous vibration.
Precision Segmented Design: Available as half-ring gears (2 segments) or multi-segment designs (4+ pieces) for easier transportation and on-site assembly of large-diameter kilns.
Advanced Heat Treatment: Subjected to Normalizing, Tempering, and Quenching processes to achieve optimal hardness (HB210-260) and wear resistance, significantly extending service life.
Superior Gear Geometry: Precision hobbing ensures accurate tooth profiles (Module 10-60) for smooth engagement with pinion gears, reducing noise and mechanical wear.
Strict Quality Control: Every gear undergoes rigorous inspection, including Ultrasonic Testing (UT), Magnetic Particle Testing (MT), and dimensional verification before shipment.
