Parameters

Module (m):

The basic unit of gear size, representing the ratio of pitch diameter to number of teeth. Standard values: 0.5, 0.8, 1, 1.25, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, 20, 25, 32, 40, 50 mm.

Number of Teeth (z):

The total number of teeth on the gear. Must be a positive integer.

Pressure Angle (α):

The angle between the line of action and the tangent to the pitch circle. Standard values: 20° or 25°.

Profile Shift Coefficient (x):

The amount of profile shift applied to the gear teeth. Typical range: -0.5 to +0.5.

Addendum Coefficient (ha*):

Standard value is 1.0 for normal gears.

Dedendum Coefficient (hf*):

Standard value is 1.25 for normal gears.

Span Measurement Teeth (k):

The number of teeth spanned when measuring the span (normal chordal) thickness of a gear tooth.

Helix Angle (β):

The angle between the tooth flank and the gear axis on the pitch cylinder. For helical gears.
