Henan San Kuang Machinery Technology Co., Ltd., a professional manufacturer established in 2022 with a factory of 10,000-30,000 square meters, proudly presents our Rotary Kiln Girth Gear designed for high-performance cement plant clinker production. This gear ensures exceptional wear resistance and strict compliance with international standards, delivering reliable operation under extreme thermal and mechanical loads. Our advanced manufacturing process and rigorous quality control guarantee that each girth gear meets the demanding requirements of modern cement plants, reducing downtime and maintenance costs.
Our rotary kiln girth gear is engineered with precision to ensure smooth power transmission between the kiln shell and the drive system. It is manufactured from high-grade alloy steel such as 42CrMo or 35CrMo, offering excellent strength and toughness. The gear undergoes a comprehensive heat treatment process (including quenching and tempering) to achieve optimal hardness and wear resistance, extending its service life even in continuous high-temperature environments.
Key Features & Technical Specifications
- High Wear Resistance: Surface hardness up to HB 260-320, with optional carburizing or nitriding for enhanced durability.
- Customizable Dimensions: Diameter ranges from 2000mm to 8000mm, module from 20 to 50, and tooth count tailored to your kiln specifications.
- Precision Machining: CNC gear hobbing and grinding ensure accuracy of DIN 6-7 grade, minimizing vibration and noise.
- Rigid Structure: Forged or cast segments (depending on size) are bolted together to form a complete ring, with easy installation and maintenance.
- Standard Compliance: Designed to meet ISO, DIN, and GB standards for girth gears in heavy industries.
- Anti-Corrosion Protection: Phosphate coating or anti-rust paint applied for long-term storage and outdoor operation.
