Let's break this down;
I posted in haste and used the term 'the bit the chain goes round'. This was not as specific as it could have been, but was not incorrect.
Several people posted that being able to name the part would help in getting an answer. I accept that and learn that next time I will try to post more precise information. It's gone, it's past, it's done with..so why do we keep revisiting this. I made a mistake and have learned from it, why keep beating me over the head with it?
Despite the failings of my description I actually got an excellent answer from pierce to that point so it did not impede the advice I got at all:

That Sheldon Brown site has pages on both of these types.
People have pointed me in the direction of a couple of website's with lots of information on them and I have accepted that I should read them and in fact have made a start on it. Your posts seem to be implying that I do not accept that I should read anything, but that could not be further from the truth. I just feel that the act of actually doing will re-enforce my learning in what is largely a practical skill.

Like Gerv said I just wanted a bit of helpful encouragement, but in part what I seem to be getting is an elitist attitude that there is no way that I could even begin to learn and should just give up now, which is only serving to dampen my enthusiasm.
