Gears.jl

This package models basic spur gears, including:

• functions for calculating involute tooth profiles
• working with gear parameters and handbook equations
• gear standards
• plotting and other geometric outputs

As these encompass a lot of terrain, the aim is not to be comprehensive but immediately useful, supporting quick prototyping of gears especially through 3D printing.

Examples

Plot a gear profile

using UnitTypes
using GLMakie
g = GearANSI( PitchDiameter(Inch(2.9167)), 70, Degree(20) ) 
fig = Gears.InvoluteTooth.plotInvoluteConstruction(g)
fig = Gears.InvoluteTooth.plotGearTeeth(g, fig)
display(fig)

Write gear profile points to a file

using UnitTypes
g = GearANSI( PitchDiameter(Inch(2.9167)), 70, Degree(20) ) 
Gears.InvoluteTooth.writeToothProfilePoints(g, fileName= "testProfilePoints.txt")
