I've been casually following this thread, so I prefix this comment with "if a comment from me isn't really isn't welcome, that's OK". The thing that comes to mind for me, if I want to combine some idea of "three" with the idea of a gear is the rotor of a Wankel engine. Those of you who don't know what this looks like might want to do a search on "Wankel rotor", and see images like the one in http://www.brandsoftheworld.com/logo/mazda-wankel-rotary One might want to stylize this a bit by simplifying it and putting a T in the middle. Further, for those who are troubled about religious connections, to the best of my knowledge there is no religion which worships Wankel engines ;-) And if someone is worried about copyright/patent issues, the similar Reuleaux triangle (still with a gear inside) might look as good.
