Normal Module (mn): The basic size unit of the gear in the normal plane (mm).
Pressure Angle (αn): The pressure angle in the normal plane (degrees).
Number of Teeth (z): The total number of teeth on the gear.
Helix Angle (β): The angle between the gear axis and the helix line (degrees).
Helix Direction: The direction of the helix (Left/Right).
Normal Addendum Coefficient (ha*): Coefficient for calculating addendum.
Clearance Coefficient (c*): Coefficient for calculating clearance.
Shaft Angle (Σ): The angle between the axes of the two gears (for the pair).
Gear Ratio (i): The ratio of the number of teeth (for the pair).
Standard Center Distance (a): The distance between the axes of the two gears (for the pair).
