I have a situation where a timing belt follows a serpentine path with toothed pulleys, and also plain rollers on the smooth side of the belts. To calculate the belt length passing over the plain rollers I need to know how far the pitch line is from the smooth side of the belt. For the FHT-1 1 mm pitch belts that I have been using so far I have an accurate profile that shows the pitch line.
Now I am going to be working with Gates GT2/GT3 2mm pitch belts. I have found a few profile diangrams on the internet, some of which indicate the pitch line. BUT there are significant differences between them! So not so helpful. There are other companies with very similar belts with names like 2GT and 3GT which is compounding the confusion. The Gates website and design guide do not show profiles.
Is there a resource that has 'official' tooth profiles of timing belts? Or even just an official profile of the GT2/GT3 2mm pitch belts? Any leads greatly appreciated.
