Pitch helix

Pitch helix

The pitch helix is the intersection of the tooth surface and the pitch cylinder of a helical gear or cylindrical worm.1

Base Helix

The base helix of a helical, involute gear or involute worm lies on its base cylinder.

Base Helix Angle

Base helix angle is the helix angle on the base cylinder of involute helical teeth or threads.

Base Lead Angle

Base lead angle is the lead angle on the base cylinder. It is the complement of the base helix angle.

Outside Helix

The outside (tip or addendum) helix is the intersection of the tooth surface and the outside cylinder of a helical gear or cylindrical worm.

Outside Helix Angle

Outside helix angle is the helix angle on the outside cylinder.

Outside Lead Angle

Outside lead angle is the lead angle on the outside cylinder. It is the complement of the outside helix angle.

Normal Helix

A normal helix is a helix on the pitch cylinder, normal to the pitch helix.
