Non-circular Gears & Uncommon Planetary Gears

We tend to think of gears as circular wheels with teeth. While this is the most common form, some gears do not have proper teeth. As the video shows here, gears do not even need to be circular in shape. These unconventional gears defy our notions about gear shapes, and are surprisingly beautiful to watch in motion.

You can learn more about gear design from the Handbook of Practical Gear Design or hundreds of other books on mechanical gears.

To the engineering-types out there: are their particularly good books on gear design? Let me know or post them in the comments here. Thanks! -Dug North

I don't know about books but your request just jogged a memory - if you are not already, then you probably should be made aware of Matthias Wandel's wooden engineering exploits. http://woodgears.ca/ there's a page off there on making wooden gears.

sweavo,

I did short blog post about the interactive gear template generator.

It may be time of a follow-up post. Thanks for the reminder!

Best,
