GT2 Timing belt pulley design


#1

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)


#2

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.


#3

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.
