gear generator question (interference )

I've used the spur gear generator to design a pair of gears meshing together, and the design went well , giving me a couple of spur gears .
I have zero experience designing gears, and my problem is that I can see that the gears generated do interference each other

Is this normal? is there a factor that I can use for less tight closeness?
here is a picture showing the problem

The gears generated by DAcc in 2009 are for reference - not for manufacture. Gears are normally purchased off the shelf from dedicated manufacturers.

Sir, 

I want to do gear contact stress analysis for that purpose I am using design accelelerator to model spur gears and doing analysis using Ansys. I am agree with your opinion, but is there any other option to avoid interference??

To get more precise toothform shape right click and select export.....

 

Toothform.png  This will allow you to specify clearance as well.

Hi,

I have that exact same problem when i use the DA when i try to create a pair of spur gears, but maybe isn´t there any other option we could use to avoid interference? we could try that, editing the tooth sketch, but is that the only way? i mean, this software is supposed to be one of the bests in this type of designs, i believe so, that´s why i use it, but honestly i´ve not been able to correct that problem.

It is best not to duplicate posts.

A better technique is to simply include reference url

You do not need to edit the sketch.

Simply set up the desired parameters in the dialog box.
