you are right there is no difference, part of my question was asking if I do a tooth correction will it still mesh with the old gears. since this is the case I will more than likely have to create a new set of gears specifically for this machine in which case I will just adjust the tooth angle.
because we have a lot of machines out in the field with this gear set-up and there is actually (4) gears in the system so if we changed the angle if any machines went down we would have to replace all the gears.
if we end up making a specific set of gears for this machine I will just change the...
So I have a set of gears
teeth:76
MOD: 3
Pressure Angle: 20 deg
pitch dia: 9.444
tooth angle: 18.1* (LH/RH)
gear lash: .003-.003
pin dia: .204
Over pins: 9.7269/9.7244
these are in a very old machine and the center distance is measuring: 9.460
we have a lot of other machines out there where...
I am working on designing a gearbox I am trying to determine what the optimal helix angle I need is and what the optimal face length should be.
besides noise reduction what advantage/disadvantage is there with increasing the helix angle? between say 15deg-20deg. is there an optimal face length...
