Anyone have recommendation on the best way to design spur gears in solid Edge 2D?

Re: 2d gear design?

What do you mean? To draw a single tooth profile or the whole gear?

Re: 2d gear design?


Hi,
I've tried to respond to this a couple of times but I must be doing something wrong.
I'll try again...
What I need to do is to draw a single tooth. I can then duplicate it for as many
teeth as I need.
I need to design a gear tooth with an involute profile. The best I can tell, with
other programs it is possible to enter equations and have the program plot the profile.
The other option I can think of is to enter equations into a spreadsheet and calculate
the points in radial coordinates and enter each point on the profile.
How can I do this in SE 2D?

Mike,
Dimensions may be driven by formulas. There is a help topic that may help
explain this usage. Dimensions are added to the variable table as they are
added. You may drive the value of dimensions by defining formulas for them.
Try this for a simple example.
With Maintain Relationships turned on, draw a rectangle.
Place dimensions for the width and height of the rectangle.
You want to define the height to be 2X the width.
Double click on the height dimension.
You will see a ribbon bar displayed with a Formula field.
Click on the width dimension.
The name of the dimension will be added to the Formula.
In the field, key in '* 2' after the name of the width dimension.
This will define the height as 2 times the width. the height dimension will
become a driven dimension.
Change the value of the width and the height will change along with it.
You can also go to Tools-Variables and see all the variables in the
document.
You can define your own formulas and use those as input to dimensions.
Hopefully this is what you are looking for.

Thanks, Rick,
I'll work on that. I think I can do what I want with that.
