Does anybody have a cad drawing of the GT profile belt? I asked this earlier in this thread as to the mesh of the two belts and the reason for choosing a trapazoidal profile versus the superior (especially in terms of backlash and power transmission) curvelinear profiles like GT.
The reason I'm trying to find an accurate profile drawing is to sketch the involute (is that the correct term?) of the belt teeth as they pull out of the "rack". This would depend on the diameter of the last idler which looks small in the original design and gives me some concern regarding backbending of the belt.
The main advantage that I can see with a T profile belt is that if will self mesh while a GT type does not (I believe) thus requireing the rack to be either machined or possibly epoxy cast using the belt as a mold.
Neat idea of turning the drive belt inside out BTW. I really like the whole concept of this flexible rack and pinion design.
Cheers
