Timing belt comparison
(OP)
Does anyone have a document or information which compares the benefits of the various toothed belt profiles? (eg HTD, AT, T, RPP, XL, L, H ...) ie. cost versus performance etc. I have access to the usual manufacturers design guides but they don't really give you comparisons they usually guide you towards their latest design.

If the mechanical strength theories & calculations hold true for elastomeric materials, the modern more "rounded" tooth designs would reduce stress concentrations at the tooth roots. Therefore you get longer life before fatigue breakdown.

I looked into this quite a few years ago. My impresson was that the metric HTD (?) series with the rounded teeth, were capable of higher speeds, and the English series belts were stiffer.
At some point, you have to believe the manufacturer's literature. Analyze your requirements and do the calculations.

The rounded profiles also run quieter and give a smoother velocity profile by reducing the "Polygon effect" of small pulleys and so are less prone to belt resonance.

Are you having trouble fitting in parts dimensioned to catalog selections?
