Precision Gear Manufacturing for Aerospace Applications

Why Precision gears matter in Aerospace industry?

In aerospace systems, gears are integral to a wide range of functions. They are used to control mechanical power transfer, adjust speeds, and convert rotational motion for various applications. Whether in jet engines, flight control systems, landing gear or even avionics, gears must perform flawlessly under extreme conditions, including high pressures, temperatures and vibrations.

The challenges of Aerospace Gear manufacturing

• Tight tolerances: Aerospace gears must meet tight tolerances to ensure smooth operation and avoid issues such as gear meshing, backlash, or excessive wear.
• Material selection: Materials must be chosen carefully to offer the right balance of strength, durability, weight, and resistance to environmental factors like heat, wear, and corrosion.
• Complex geometries:Gears used in aerospace applications often require complex geometries. Advanced manufacturing techniques are required to produce these intricate shapes with precision and consistency.
• Quality Control: Every gear must be inspected and tested to ensure it meets the highest standards of precision, durability, and performance.
