Sprocket Add-In
Use the Sprocket Add-In to create the geometry for a sprocket. You can customize the result by choosing parameters such as the number of teeth, the roller diameter, and the pitch.
The following chart lists dimensions for standard chains used with sprockets:

Number of teeth
The number of teeth in the gear. Causes the outside diameter, root diameter, fillet radius, roll diameter and roll measurement to be recomputed.
Pitch
The distance between the center points of adjacent roller arcs, as shown with the red line in the image below.
All teeth
Specifies that the Add-In should create the geometry for the complete sprocket.
Roller diameter
Specifies the diameter of the roller's arc.
Tip fillet radius
Radius of the fillet connecting the top land to the involute.
One tooth
Specifies that the Add-In should create geometry for only a single sprocket tooth.
