Now for the third 'virtual rolling motion' we leave the large gear fixed and roll the small gear back towards the top, rolling along the large gear. In the 'x' direction, the top gear is centered between the bottom gears. This gives us the first constraint, which provides heta_2 as a function of r_1, r_2 and heta_1 We remember this position (indicated by the dotted outline), and then for the second motion both gears continue to rotate for a total angle of heta_2. For the first rolling motion, both gears are rotated together through an angle of heta_1. A radial line marks each gear so we can track their angular position. We start with the gears arranged as shown at the top of the figure. Then we search for values of heta_1 that satisfy both constraints. We are given the pitch radii of each gear, r_1 and r_2, and the diametral pitch DP (which must be the same for both gears).

There are two constraints on the system, which can be found by starting with two gears in an initial configuration and then making a sequence of three 'virtual rolling motions'. You will need the zipped code from this page and FDavies's file to run under Octave. If you don't have access to MATLAB, the code should probably work with GNU Octave with minor modification.ДЇDavies posted an Octave-ready version of the script here.

This page has a brief description of how he solved the problem, as well as MATLAB code you can download to generate your own gearing arrangements if you are using this particular mechanism. Matt Moses solved this problem while working on a linear motion mechanism of his own, which uses a similar arrangement of gears. He stated: 'there's probably an ideal solution when solving simultaneously for (a) a rack, with (b) two gears of radius R1, being driven by (c) another larger gear of radius R2 all for a given tooth size.'

Update 1.4: TA-DA: Added internal gear support, and the ability of positioning the first gear. Maximum number of teeth increased to 400. The downloaded DXF file can be opened with AutoCad 2013 or newer versions. The winners are: Opera for the best performance (shame on me, I never use it) and Firefox for the best looking SVG render. Support: about browser compatibility: all new major browsers are supported (i didn't tested IE), but unfortunately Chrome can't render SVG circle correctly. It was a pleasure to code the whole thing, I'm a bit sad it is already done. As it was done, I couldn't stop, and I added more and more features, and finally I got this tool. 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. Gears can be animated with various speed to demonstrate working mechanism.

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. Gear Generator is a tool for creating involute spur gears and download them in DXF or SVG format.
