Forging
1. Heating and Temperature Control
·Heat the billet to the precise forging temperature range.
·Strictly control the heating rate and holding time to ensure the billet is fully heated and the temperature is uniform, preparing it adequately for plastic deformation.
2. Multi-process free forging forming
·Bending and elongation: Under a large hydraulic press, the billet is repeatedly subjected to bending and elongation.
·Shaping and final forming: Through processes such as precision pressing and flattening, the outer diameter, inner diameter, height and wall thickness uniformity of the forged billet are made to meet the requirements specified in the drawings.

Rough Turning
Hobbing
Rough turning of the spur gear end face, performing initial face shaping and dimensional control while leaving appropriate allowance for subsequent finishing operations.
Hobbing process of the spur gear, with strict control of tooth profile accuracy and helix angle to ensure proper gear meshing and stable transmission. Cutting parameters, tool condition, and feed are carefully monitored to ensure the gear dimensions and surface quality meet design specifications.

Shrink Fit
The shrink fit process of the gear ring is as follows: By controlling the heating, the size of the gear ring hole undergoes thermal expansion, thereby forming a tight fit with the shaft. 
The heating temperature and assembly position are carefully controlled to ensure accurate axial position and guarantee the integrity of the connection, thus achieving stable operation.

Magnetic Particle Test
Magnetic particle test is conducted on the gear teeth and critical structural areas of the spur gear to identify surface and near-surface defects that may arise during machining or heat treatment.
The inspection provides quality verification for subsequent processes and assembly.

Packaging
To ensure that the product is protected from impact, corrosion, or deformation during long-distance transportation and multiple handling operations, a multi-layer export packaging solution is adopted, as detailed below:
1. Inner Protective Layer
All critical surfaces of the product (such as machined surfaces, mating surfaces, end faces, etc.) are coated with anti-rust oil or suitable protective agents and wrapped with VCI (Volatile Corrosion Inhibitor) paper or other protective materials. This effectively isolates air and moisture, preventing corrosion or damage during transportation and storage.
2. Cushioning and Fixation Layer
Cushioning materials (such as pearl cotton, foam, or rubber pads) are applied around the product to provide full protection. Customized supports or positioning blocks are also used inside the packaging case to prevent rolling or displacement of the product, ensuring stability during transport.
3. Outer Reinforced Packaging
The outer layer uses a reinforced export wooden case or other sturdy packaging with strong structural integrity and high load-bearing capacity, suitable for sea, land, or air transport. Handling marks such as center of gravity, lifting points, moisture protection, and anti-tilt symbols can be applied according to customer requirements, facilitating on-site handling and identification.
4. Customized Packaging Options
Packaging solutions can be customized according to customer requirements, including protection grade, cushioning method, fixing structure, and outer case design, to meet different transportation conditions, destination ports, and project site requirements.
