Making a Spiral Bevel Gear 

Spiral bevel gears are a type of gear that features a spiral cut tooth shape, which allows for smoother and quieter operation compared to traditional straight-cut gears. They are commonly used in applications where high speed and low noise are required, such as in:
- Automotive differentials
- Aerospace applications
- Industrial power transmission systems
- Robotics
Spiral bevel gears have several advantages, including:
- Increased tooth contact ratio, which reduces noise and vibration
- Improved efficiency and reduced friction
- Ability to handle high speeds and loads
- Compact design, making them ideal for applications where space is limited.
