These settings determine the distance between teeth (Circuilar Pitch) and the sharpness of the gears teeth (Pressure Angle).Gears from this set, printed from ABS on an up3D printer, have been tested thoughtfully, but Id wager that they would also work well for laser cutting.History Back in the day I had a some Lego Technics that came with a set of plastic gears that I absolutely loved to fiddle with.I spent hours building little contraptions only to tear them apart and build something else.
Eventually I left the legos behind and moved on to building things from scratch materials, but I never really had a way to make gears myself and ended up just buying motors with gears already attached. Fourteen-years later 3D printing becomes something that you can do at home, and with it came the ability to just print out my own gears. Remembering my Lego set, I headed out with the goal of creating my own version that could be mixed and matched for whatever thingamajig I was was working on. It took a lot of software hopping and a lot of test printing, but eventually I was able to make a set of gears tuned for the up3D. ![]() The gears are made to the absolute smallest size that I was able to print f while still getting something that actually works. The rest of this Instructable will explain how to generate vector gears, make them into 3D solids, and ultimately, design gear boxes around them. I must warn you, this method is more convoluted than ideal as it uses a total of four programs to get from vector to dwg, but the end result is worth it in my opinion. Its worth noting that Autodesk Inventor (not Inventor Fusion) can generate 3D gears all by itself. I would have just used that but, well, it had lots of options that I didnt understand. Although I like to pretend, I am not a professional engineer and the finer points of gear design are lost on me. For the purpose of these instructions we are not going to worry about all of the variables, as they would likely just hinder the creative process. Cutting these corners will result in a less than optimal gear, but you know, whatever, they work. To use the gears presented here you only need to concern yourself with a few things. The chart above lists the center distances for all of the gear pairs that can be made with the set, by referencing this chart you can easily connect gears to each other and design supports. There is a PDF version of these charts attached to this page. 3D Gear Software Download Add TipAttachments Gear Set 1 - Specs.pdf Download Add Tip Ask Question Comment Download Step 2: Auto-Generated Vector Gears. 3D Gear Software Generator At WoodgearsI know of two ways to automatically generate vector gear outlines: with inscape (which is what will be used in this Instructable), and the gear template generator at woodgears.ca. To use woodgear.ca templates youll need to save the page as a pdf, then it can be opened in Illustrator. For the most part, I picked this tecnique up from this Make blog that explains a bit more about gear specs. Creating Gears with Inkscape. Set the number of teeth you want, set the circuilar pitch to 5.3 pixels, and set the pressure angle to 20 degrees.
