Gear Generator is a tool for creating involute spur gears and download them in SVG format. In addition it let you compose full gear layouts with connetcted gears to design multiple gears system with control of the input/output ratio and rotation speed. Gears can be animated with various speed to demonstrate working mechanism.

Why this tool was created? Just for fun. I'm working on a hobby project, a scale construction machine, which needed some spur gears, and i quickly made a simple spur gear creator script in Javascript with SVG output. As it was done, i couldn't stop, and i added more and more features, and finally i got this tool. It was a pleasure to code the whole thing, i'm a bit sad it is already done, so if you have any idea, what would be a helpful feature, just let me know by sending an e-mail UPD: Thanks for all the great ideas you've sent me, i just need to focus on Print-Charts these days to make some money to keep GG alive as a free tool.

Notes about browser compatibility: all new major browsers are supported (i didn't tested IE), but unfortunately Chrome can't render SVG circle correctly. The winners are: Opera for the best performance (shame on me, i never use it) and Firefox for the best looking SVG render.
