About this product

Product information from the supplier.

Our Large-Module Gear Ring Blanks are high-precision forged components specifically engineered for the most demanding heavy-duty applications. Designed for seamless integration into mining machinery, rotary equipment, and industrial drive systems, these blanks provide the critical foundation for large-diameter gear rings where structural integrity and load-bearing capacity are non-negotiable.

By focusing on a controlled forging route, we ensure a sound internal structure and minimized deformation, providing optimal stock for tooth machining. Whether supplied as raw forged rings or rough-machined blanks, our products enable customers to execute gear cutting and heat treatment according to their specific technical standards, ensuring maximum stability during the final hobbing and milling processes.

Frequently Asked Questions

Q: What are the primary advantages of using forged gear ring blanks over cast ones?

Forged blanks offer superior mechanical properties, including higher fatigue strength and a denser internal structure with continuous grain flow, which is critical for large-module gears in heavy industrial use.

Q: Can you provide customized heat treatment for the ring blanks?

Yes, we can arrange normalizing, quenching, and tempering based on your specific technical requirements to ensure the material responds correctly to subsequent gear cutting.

Q: What ultrasonic testing standards do you follow for these forgings?

Our inspection processes typically adhere to ASME A388 or EN 10228-3 standards to ensure the full volume of the forging is free from critical internal defects.

Q: What is the maximum diameter and weight you can produce for gear rings?

We can produce gear ring blanks with outside diameters up to 8000mm and individual unit weights reaching up to 30 tons.

Q: Do you provide rough machining services?

Yes, we offer rough turning and machining of the OD, ID, and face surfaces to provide a precise blank that simplifies your final gear cutting process.

Q: Which materials are most recommended for mining rotary kiln gears?

Depending on the load and wear, materials like 42CrMo4, 34CrNiMo6, or 18CrNiMo7-6 are highly recommended due to their excellent hardenability and toughness.
