Parameters Explanation
Module (m)
The module is the ratio of the pitch diameter to the number of teeth. It determines the size of the gear teeth.
Pressure Angle (α)
The angle between the line of action and the tangent to the pitch circle. Standard values are 20° or 25°.
Number of Teeth (z)
The total number of teeth on the gear. This affects the gear ratio and overall size.
Addendum (ha)
The radial distance from the pitch circle to the top of the tooth.
Addendum Coefficient (ha*)
A standard value (typically 1.0) used in calculating addendum.
Clearance Coefficient (c*)
A standard value (typically 0.25) used in calculating dedendum.
Modification Coefficient (x)
Used for modified gears; affects tooth thickness and profile shift.
Gear Speed (RPM)
Rotational speed of the gear in revolutions per minute.
