I implemented an online lantern gear builder to complement my other online gear generators.

The gear meshing with the lantern gear is created by tracking how the lantern gear pins cut into the disk of the matching gear. As an example, the image on the right shows the path of one lantern pin moving clockwise into the 3 o’clock position. The same circles, pinned to the matching gear, create the shape of a half tooth as the matching gear turns counterclockwise at a speed defined by the gear ratio. (I use the same mechanism for the involute spur gear builder).

The complete list of gear builders is:

  1. I see we have similar interests. I was rethinking my lantern gears, which have worn after 6 years of operation, and encountered your gear generator. Thanks! In the clock you see below, I decided that only one tooth needed to be engaged at a time. This means that you only need the bottom mm or so of the wheel gear bearing surface. Because the surface is so short I figured that a flat profile was sufficient. The clock seems to work just fine, except for wear. I would be interested to hear your thoughts.

  2. Hi! Just wanted to say thanks, I’m a student and was curious about these gears, couldn’t find much info out there. I used your program to 3D a simple 1:3 gear ratio toy with them. Thanks for the tool!
