Belt Drive Design Problem

192 hasn't had a problem with this on the 5mm pitch drive belts that share a pulley. However on the prototypes of the 2013 gearbox the higher tension 3mm pitch belts would drift more and rub. This was made worse by their arrangement where they crossed over each other. We saw the sides of the belts wearing down so we added a flange on the final version to prevent the rubbing. Should be noted no damage was done to the tensile members and only to the rubber backing.
