GT2 Timing belt pulley design


Hello how do i design a GT2 timing belt pulley from scratch with the correct tooth / grove profile?

(I already know how to use CAD I’m just wondering about how to dimension the profile given the amount of teeth of the pulley)


Do you an old pulley that you can measure/reverse engineer? There maybe an ISO or ANSI spec available for that specific belt design/profile. However you generally have to buy these spec and they are not the cheapest thing either.


if you have a belt you can use its measurements to dictate the tooth grove profile. just keep in mind that that pulley profiles for the tooth are usually only a few tenths of an inch and generally a bit less than the belt groves are deep.
