Spiral Angle (β): Typically ranges between 25° to 40° for smooth operation and noise reduction.
Shaft Angle (Σ): Commonly 90°, but can be adjusted based on design requirements.
Gear Material: Alloy steels (e.g., 20CrMnTi) are often used, with carburizing heat treatment for enhanced hardness and wear resistance.
Accuracy Grade: Determined by standards such as AGMA (American Gear Manufacturers Association) based on application needs.
