Can anybody please help me.I am trying to figure out what the gears is.I have the a pinion right in the centre with one out of the three gears.The internal gear i don"t have and cant get hold of it so here is the measurement i took which is fairly accurate.
pinion:
teeth = 16
OD = 41.3 mm
Root diametre = 32.6 mm
gear
teeth = 31
OD = 73.5mm
root diametre = 64.7mm
so what i tried was mod 2.25 then it works out that the pinion was enlarged and the gear reduced.The thing that i dont understand is the whole depth.It is way to shallow.It looks like a 20degree pressure angle but i have even worked it out in 14.5 and it is still not enough.Maybe it is a stub tooth??i dont know all the formulas ect.Can anybody please help me and try to explain??
