Gear Generator

Postby Kitecraft » Tue Dec 23, 2014 9:50 pm

I wiped up a gear generator based on the MCAD 'involute_gears.scad' libarary
Hopefully, this makes creating gears very easy since all you have to do is plug in some numbers and press F6.

Options include:
- recessed sides (single or double sided)
- gear hub (single or double sided)
- set screw in the gear hub
- relief holes

Example to make a gear with recess sides, double-hubbed with set screw and relief holes (see attached image):
gear (circular_pitch = 88,
number_of_teeth = 64,
gear_thickness = 7,
bore_diameter = 3,
recess_thickness = 2,
recess_diameter = 28,
recess_double_side = true, //default false
hub_thickness = 6,
hub_diameter=5,
double_hub = true, //default false
hub_set_screw_diameter=1.5,
num_relief_circles=5,
relief_circles_diameter=5
);

You should also check out http://www.gearotic.com - Art's gear software is just amazing. It's from the same person that wrote the Mach3 machine control software.

I use gearotic to cut metal gears on my Tormach Mill. I have cut and hobbed a lot of gears and this software generates a gear that is as accurate as I can measure. It is based upon a process called gear shaving and generates a geometrically perfect gear tooth.

If Art developed a slicing program, I'd be standing in line with money in hand. Ditto if he developed a plug in for Mach 3 or 4 to run a delta printer directly from a pc.

I would have to agree on that. All my experiences with Art's work have been excellent!

I run Mach 3 on my Tormach. I am currently running some plaques of running horses cut in raised relief in wood. These are cut from an .stl file also.

With a 1/16" ball nose end mill the CNC code for the 15 x 4-1/4" plaques is 1.4 Million Lines long, Mach 3 runs it flawlessly.
