Problem Encountered; need advise

Harold:

  Im of the opinion your fine. As long as the tooth space is larger , the teeth of the wheel will fit.
The teeth dont have to hit both sides, youll be turning in one direction only, right? you could is essence cut each tooth in half
and use only the ide facing the direction of rotation. In fact cutting edge gears are now doing that and calling then asymetric
tooth forms.
  I think the drawing you have will work fine, as I said, Im not sure you have a full concept of just how much wiggle room you have on
a low speed , relatively low torque gear. So long as it fits on the shaft and its teeth fit reasonably into the wheels spaces..youll be fine..

worst case..it will wear a bit faster than otherwise..

Hi Harold:

  As you shift a gear positive, the spaces shrink between the teeth, the theory being the spaces on the other will be enlarged.

What you need is the width at the pitch line on the other gear, no other measurement is real important. If the width on the mating gears pitchline is X, then if yours is <=X your gear will work. If you have the capability to shift the center distance then you wont have any trouble no matter what you do, if you profile shift your gear outwards by .6 as John did, that implies only that you need to shift the center away from the original mate by the same shift if you dont intend to recut that one.

Ok Art, I think I am beginning to understand. When I read one of your earlier posts, I somehow got it in my mind that the new pinion gear had to be equal to or have less distance at the pitch line than the older pinion gear. Since reading your statement again, the space to which you were referring was space on the mating gear’s pitch circle. I haven’t even begun to attempt calculating the pitch circle diameter of the big wheel. However, since I have the motor mounted on a sliding plate, I can either move the motor closer or further away when meshing the gears. According to your statement, if I understood it correctly, I should have no problems because I can move the entire motor closer or further away as necessary when meshing the gears. Did I read that correctly?

Yes, exactly. It sounds to me like your calculations so far are good, so you should be close enough that
sliding back and forth will get you in mesh, your pressure angle may not match up exactly, but you have no real load
and no high speeds, so Ill bet it works fine.

Thank you very much for hanging in there with me. Very much appreciated.
