Gear
Generator
* Shift + Enter: modifies the Diametral pitch
Gear Generator is unitless: if you wish it's inches, cm or millimeters. DXF opened in AutoCAD will have the same value for D/P as it is set above. Gears in SVG are measured in pixels, which is the value multiplied with the scale (Pixel per Unit) as it is displayed on the right side.
Gear Generator is a tool for creating involute spur gears and download them in DXF or 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.
Support: abel@iparigrafika.huNotes 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.
The downloaded DXF file can be opened with AutoCad 2013 or newer versions.
Update 1.5: Fixed DXF resolution issue. Maximum number of teeth increased to 400.
Update 1.4: TA-DA: Added internal gear support, and the ability of positioning the first gear.
Update 1.3: Fixed DXF file format.
