Key Features & Technical Specifications
- Surface Induction Hardening: The tooth surface is hardened to 58-62 HRC, providing excellent wear resistance while maintaining a tough core for shock absorption.
- High-Strength Alloy Steel: Manufactured from premium alloy steel (e.g., 42CrMo, 35CrMo) with strict quality control to ensure uniformity and reliability.
- Precision Machining: CNC machining ensures accurate tooth profile, smooth operation, and low noise during rotation.
- Customizable Dimensions: Gear module, number of teeth, bore diameter, and overall dimensions can be customized to match your existing rotary kiln specifications.
- Heat Treatment Process: The induction hardening process is precisely controlled to achieve the required hardness depth and pattern, minimizing distortion.
- Rigorous Testing: Each girth gear undergoes ultrasonic testing, magnetic particle inspection, and hardness verification to ensure defect-free quality.
- Long Service Life: Designed for continuous operation in cement plants, with a lifespan significantly longer than traditional through-hardened gears.
- Easy Installation: The gear is machined with accurate mounting holes and keyways, simplifying assembly on the kiln shell.
