Customized 35CrMo forged steel segmented large diameter ring gear

1 Overview of segmented ring gear

The segmented ring gearis a transmission component specially designed for large mechanical equipment such as rotary kilns, ball mills, etc. It simplifies the installation and maintenance process by dividing the entire ring gear into several segments. Each segment is independently manufactured with high strength and wear resistance, and can withstand large loads and complex working conditions. This design is not only convenient for transportation and assembly, but also only replaces the damaged part when worn or damaged, reducing maintenance costs and extending the service life of the equipment. In addition, the design of the segmented gear ring optimizes the mechanical transmission efficiency and improves the overall performance of the equipment.

3. Segmented gear ring production process

-Forging

The steel is initially formed by die or free forging to obtain a rough gear ring shape.

– Heat treatment

After preliminary mechanical processing, in order to improve the comprehensive mechanical properties (strength, hardness, toughness) of the material, a quenching and high-temperature tempering quenching treatment is required.

-Machining

Rough turning: Use CNC lathe to perform preliminary turning on the forging to form the basic geometric shape.

Fine turning: Further turning to achieve more precise size and surface finish.

-Inspection and testing

Dimension detection: Use three-coordinate measuring machine, gear measuring instrument and other equipment to check key size and shape tolerance.

Non-destructive testing: Such as magnetic particle testing, ultrasonic testing, etc., to ensure that there are no cracks or other defects inside.

Performance testing: Hardness testing, tensile testing, etc. are carried out as needed to verify the mechanical properties of the material.

– packaging

Assembly: If necessary, assemble the processed segmented gear ring with other components into a complete rotary mechanism.

Packaging: Finally, clean and rust-proof treatment is carried out, and it is protected with appropriate packaging materials for transportation and storage.
