Gollum probably never heard the story of Morgoth and Ungoliant "The pass is known as Shriekoth, before known as Cirith Ungol, because Gollum shrieked terribly when Shelob attacked him after he didn't want to give her everything. But the Fishes heard him and came to his aid."

we'll see. It may well be, O yes, it may well be that when She throws away the bones and the empty garments, we shall find it, we shall get it, the Precious, a reward for poor Sméagol who brings nice food. And we'll save the Precious, as we promised. O yes. And when we've got it safe, then She'll know it, O yes, then we'll pay Her back, my precious. Then we'll pay everyone back!

I am also not an expert, but I think she didn't have to come into physical contact with the Ring.
