What is the pitch of a worm gear?

The pitch in worm gears is the axial pitch, the pitch always being expressed in the axial plane. When the helix angle exceeds 15º normal pitch may be calculated by multiplying the axial pitch by the cosine of the helix angle. This pitch is measured perpendicular to the sides of the thread.

How do you find the pitch of a worm gear?

Circular pitch (CP) is a direct measurement of the distance from one tooth center to the adjacent tooth center. In a worm drive, it is called axial pitch and can be measured by the formula CP= Π ÷ DP.

What is the formula for the lead of worm?

Worm Gear Formula Table

To Find Rule
Worm Lead Divide 3.1416 by Diametral Pitch and Multiply by Number of Threads in Worm
Co-Tangent of Worm Helix Angle Multiply Worm Pitch Diameter by Diametral Pitch and Divide by Number of Worm Threads
Center Distance Add Worm Pitch Diameter to Worm Gear Pitch Diameter and Divide Sum by 2
