A small doubt on gears

I have this doubt on spur gears
Is it necessary that the pitch circles of the two mating gears need to be tangential? or will a small gap of 0.3mm matter?

I think a gap that large will cause slip. Thus I should think they need to be tangential. Hoping for someone to come in and confirm that though.

I'm not sure if this is what you're talking about, but you can read about extended center distance.

A small doubt on gears

I think he is talking about circular pitch. In which case I would think this has to be tangential.

I am trying to find some engineers who might know the exact answer.

I always thought that the pitch circle was tangential by definition. Isn't it defined by the line of action?

Or are you talking about pitch as in teeth/length?
