Anywho, I've searched far and wide for another similar program but have come up with nothing. I understand how to make a standard spur type gear, but there are some that I can't grasp. I'm looking at miter and bevel gears out of the Small Parts Inc catalog and pulling other bits of information out of my Machinery's Handbook to try and make the gears on AutoCAD but it is a real pain.

Anyone know of an easier way to make gears?

I talked with some people about this question and what we decided is this:

Take the pitch diameter, and create a model of the gear (hub, bore, whatnot) but instead of teeth just make a cylinder with a diameter equal to the pitch diameter.

Inventor doesn't care about the difference. It is surely loads easier on your system (especially when you are placing/moving them . . . this can take some time on a middling machine).

So my advice is to just model the gears minus the teeth (using, again, the pitch diameter).

Re: 2D/3D Gear Design

The point is that I want the teeth to be shown.

Re: 2D/3D Gear Design

Perhaps putting a bitmap on the cylinder would suffice?

Perhaps you could find what you are looking for at www.cadregister.com

Ok, this is possible.

First, you need to find dimensions for each individual tooth (i.e. how far below the pitch diameter is the trough, how far above is the peak, what shape is it, etc.) and draw one tooth, then use circular pattern to draw all the teeth (after you extrude the first makes it easier) and viola.

But, you were asking about angle gears, weren't you.

In the FIRST CAD library thread there is a link to another collection of inventor files, and they have some angle gears there. Check them out.

As I said, I'm using AutoCAD not Inventor. I want to know how to create the gear, of any size from the info given. there are no iParts for AutoCAD that I know of.

I have the following information for each gear:
Diametrical Pitch
Number of Teeth
Pitch Diameter
Face
Bore
Mounting Distances
"D" (Base of Hub to Plane)
Hub Diameter
Hub Projection

Re: 2D/3D Gear Design

is this what you are looking for?

most of these can be changed to any size gear by just changing a few numbers.
