interference on helical wheels

[roberta.f]

Good morning to all, I've been following the forum for a while, but this is the first discussion I open, so I introduce myself briefly:
I am a mechanical engineering student, next to the three-year degree, use solidworks for a couple of years, but exclusively in the field of university projects, so I have no particular technical experience.
I am currently working on the project of a parallel axle reducer with helical wheels. the project is practically ready, but regarding the model on solidworks I still have uncertainties regarding the couplings between the wheels. the constraints I set are the intersection and a gear mate between the pairs of trees, but it is practically impossible to position the wheels so that there is no interference between the teeth. the wheels are taken from the toolbox, so the coupling should be right, but I can't set any tangency that does not create interference. I didn't find any such discussions and the professor didn't help, but it requires that there are no interference. I don't know if there's a solution or you should leave everything as it is.
Thank you so much for your attention!

If the positioning is done by hand, to avoid interference is extremely difficult. obviously sena file is impossible to help you.
However unless you have to do simulations or other analysis these interferences are not important; to understand is the same thing as an interference between the screw is the threaded hole with cosmetic thread

if the positioning and the intersection is correct I do not see the problem, are "false" interference.
I regret the times when the gear was an external diameter, a primitive and the hub with processing. . .

Thank you so much for the answers, I thought it was conceptually not a problem, but I thought I was missing something.

the coupling gears must however start from a position where the components are not in interference. to do so I would try to do a sketch point on the average compartment of both components and then make a tentative bond of coincidence between them.

toolboxes are simplified gears and therefore do not have the profile to evolve. Therefore being so and by far no names (i.e. without game) you can never use the model for a simulation of this type and even for 3d printing.
In addition, I hope you don't have to get into the profile shift, which is actually a common practice, otherwise you can beat everything.
the models you can simply build them with real profile with freecad with workbench fcgear ... all free. otherwise kisssoft and ask for student license.

I had initially tried to impose the tangency between the sides of two teeth, but still remained a slight interference, it could be due to the approximation of the profile, however later I will try so.
