Drawing gears
Drawing gears
(OP)
Let me start off by telling you why I write.
I have been a laser technician for a few years now, and have taken a shine to drawing items in auto CAD.
Well, the engineer here was fired and I was tossed into this position. I am starting to sink and need a ton of help.
My question is, " How do you draw a gear in AutoCAD 2000"?
Thanks,
-Tim

You might find someone somewhere has done a LISP routine to generate them quickly though..
I'm sure you know how to generate an involute, but just on the off chance you don't: imagine a piece of string wrapped around your diameter. Pull on the string to unwind it, keeping it taut - the end of the string will be following an involute shape. Just construct a series of points that the end of the string will pass through in autocad, and then join them all up with a spline.

I have a story. I joined a company that had trouble with worm gear mismatch. The worm was not 90 deg to the gear axis. The error was about 10 deg. I found that the gear was drawn incorrectly, and the mfr made gears according to the drawing, not the published gear data. Add a note to the drawing:
(Critical sign) N. Gear tooth details shall be according to the gear data tabulation, not the drawing of the gear.

I hope that you've found the AutoCad forum (Forum555) at this site...
