I'd like to change this so that it no longer needs convertcp() which I see as a Gear (number_of_teeth = 10, circular_pitch = convertcp (5), flat = true) Perimeter between teeth) of 5 and 10 teeth: This for a 2D gear with a circular pitch (distance along the pitch circle's I've provided a function for this called convertcp(). (something to do with radians that I don't quite understand, but have worked outĪ formula to convert circular pitch from length units to whatever gear() Like some have noticed, circular_pitch in the gear module uses broken units Get Doxygen documentation on the entire library, but first comes tidying up the Hmm, a couple of the descriptions are a bit off, and I'm hoping to eventually > Or, maybe even better as Doug suggested it could be added to the > gear scripts are likely the most used part of MCAD. > This page is really in need of some love and it looks like the > I'd like to ask if it could be added to the MCAD page on the Wiki.

Library is fantastic, but for someone with no engineering background theĬalling parameters are cryptic. PolyGearAll.I am a hobbyist wanting to print gears for gizmos.

It serves as documentation for the computations implemented in PolyGearBase.scad 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 PolyGearUtils.scad - collection of more and less trivial complementary functions PolyGearBase.scad - computation of the gear profile and some meshing functions PolyGear.scad - main file, the one that you should read and use in your project

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.
