Wheel toothed

hello !!!
I’m confused by a model I thought simple, but, mmm, it’s not so simple (for me!): a wheel toothed, but the teeth are, at the beginning, at the same thickness than the cylinder of the wheel, but they become narrower at the “end”… oh, and I need to bevel the whole wheel, after… I’ve tried dofferent things, but without success!!! thank you for your advice!!!
