It serves as documentation for the computations implemented in PolyGearBase. Shortcuts.scad - a slightly enhanced version of the excellent shortcuts library by ParkinbotĪ copy of the nice open access paper which I use for the generation of the involute profiles. Linspace.scad - lightweight library for producing range of points A library for the parametric creation of gear racks, spur-, ring-, bevel- and worm gears, as well as of assemblies. PolyGearUtils.scad - collection of more and less trivial complementary functions PolyGearBase.scad - computation of the gear profile and some meshing functions Profile shifting To cut a gear with profile shift x the tool is moved at a radius. PolyGear.scad - main file, the one that you should read and use in your project l gear cutting with free profile shift openscad library 3d models. I would expect that the comments in the code and the demo example should suffice as user documentation, but if I collect some good questions I may compile a FAQ. Do not expect lightening holes or other gimmicks, but comprehensive and efficient control over your gear teeth. My aim has been overcoming these limitations. I wrote this library because I was unsatisfied with the existing ones:īeing, to my taste, either too hampered, fragile or computational expensive. The gear is constructed in an extremely efficient way, by triangulating a minimalist vertex cloud with a single polyhedron. The library allows full control of the involute tooth profile, including pressure angle, backlash, variable helix angle, addendum, dedendum and profile shifting.īeing able to vary the helix angle allows for instantaneous generation and switch between herringbone, zerol, spiral and customized profiles all constructed as a single and smooth polyhedron even for small facet number. “PolyGear is a powerful OpenSCAD library for the generation of spur and bevel gears as a single polyhedron.
