Characteristics
Aviation gears need to withstand high loads and torques while maintaining their integrity. They are designed to be extremely rugged and durable to ensure reliable performance in extreme conditions. Aviation gear is typically made from lightweight materials such as titanium or high-strength aluminum alloys to minimize weight while maintaining strength. Aerospace gears are designed to minimize noise and vibration through advanced tooth profiles, optimized gear mesh, and the use of noise-dampening materials.

Mainly engaged in the design, processing and sales of high-precision, high-strength, small-module spiral bevel gears, high-reduction ratio hypoid gears, and cylindrical gears.
Processing Features:
1. DH precision manufacturing: Spiral bevel gears require precision manufacturing processes due to their complex tooth geometry. Gear teeth are typically produced using specialized cutting tools, the accuracy of the cutting process directly affects the performance and durability of the gear. We have multiple CNC 7-axis 5-linkage spiral bevel gear grinding machines and gear milling machines, which can process high-reduction ratio hypoid gears and end-face arc tooth couplings.
2. Gear grinding: After the initial cutting process, spiral bevel gears often need to be ground. Grinding helps improve gear tooth surface finish, accuracy, and tooth-to-tooth contact. Ensure correct gear meshing to reduce noise and vibration during operation.
3. Heat treatment: Heat treatment is an essential step in processing spiral bevel gears. It involves heating the gear to a specific temperature and then quenching it to achieve the required hardness and strength. Heat treatment helps improve gear durability and wear resistance.
4. Inspection and Quality Control: Due to the critical nature of spiral bevel gears, strict inspection and quality control procedures are adopted during their manufacturing process. In order to ensure the dimensional accuracy and tooth profile consistency of the gears, we use various measurement methods, such as three-dimensional coordinate measuring machines (CMM), and we use the high-precision gear measurement center to complete the gear pitch accuracy detection, tooth profile error detection and reverse correction of tooth profile errors.
