Several years ago, I realized that I didn't understand gear geometry, so I pulled out my old edition of and made an that could generate a few different kinds of gears with a few different options. Works okay in most cases, but I'm wondering how others do it. I'm aware of some professional tools, but are there other tricks?
Involute curves in feature-based CAD sketches? What about and gears, which don't lend themselves so easily to planar sketches?I haven't used my generator for anything serious, but have had a bit of fun.
The beautiful thing with Fusion 360 is that you can simply delete geometry you don’t want by clicking on it and hitting delete. Fusion 360 will delete the part and automatically heal the body. One tip to note is that if there is a fillet or chamfer you’ll want to delete that feature first. For modeling a TRUE Involute Spur Gear in Solidworks This template is built with some 'IF' 'THEN' statements So it is a bit more Robust than my previous postings This is with the Gullet of the first tooth cut on the 'Y' axis Note: use the updated file: 'Robust Involute Spur Gear Generator - Better 02.SLDPRT'.
The main 3D modelling software I use these days is Alibre Design, a low cost but very feature rich and easy to learn an use product. This software in some areas even out performs many of its much more expensive rivals. In the past, I generated gears using an old version of Solid Edge ( V12 ), as it had an excellent tool for this. I could export gear as a stp file or as my Alibre Design software can open Soild Edge files directly I could just open them.
The only problem is they are just dumb solids. I joined Alibre Design forum, should have done this years ago, and discovered a free add on python scripting tool.
This tool has built in functions for generating gear profiles, though I am uncertain of how close to a true involute tooth is produced. But as I am not using this to directly machine gears it does not matter. I have gears made by a specialist gear manufacturer with good gear making machines and skilled men operation them, i just supply a specification. Here is a link to Alibre Design Group on GrabCad.
I have a post on this forum as regards to generating gears with this tool. As i am new to this tool I have, at this stage, developed a script to generate plain spur gears from required module and number of teeth. I am also working on scripts to generate helical and bevel gears.
Hey all,I have access to a lasercutter, and one thing I'd like to play around with is to create some lasercut gears. Does anyone know of any good/easy software i could use to generate basic gears in DXF or other vector format for use in a lasercutter?also, i dont know much about gears, but i basically want two meshing circular gears. I'm not sure about the ratio, but i think 2:1 would be a good start. What is the best type of gear to use? I dont want to get too complex.
Simple and robust is the idea here =)what is a good minimum size i should keep in mind as well? Hey ZachI don't really know of any of the parameters that would be good to use for gear from the laser cutter, but I have been working in Autodesk Inventor 10 recently. If you can get your hands on the trial version, I think you'll be amazed at how easy it is to create any DXF file. All of the gear create menus etc.
Are completely intuitive.Just as a side note to prove my point. All of the kids in my highshcool pre-engineering class had to learn how to use the software in order to pass, so I think you will be able to as well. Hope that that endorsement helps!Jay.
