Selecting pitch of gears for a spur gear train
Selecting pitch of gears for a spur gear train
(OP)
I am designing a simple spur gear train. Goal is max output torque & high efficiency. OD of gears is pretty much fixed.
Could someone please suggest what would be the optimum pitch which I could consider? I am thinking 12 or 16 dp. However, I am not sure how much of a friction loss there will be with coarse pitch gears.
What are the other advantages and disadvantages of using coarse gears over fine pith gears other than noise?
Any feedback is highly appreciated.
Thank you.

If you are going to use coarse gears, the surface endurance is going to be reduced because your effective contact surface is going to be smaller. Problems as pitting appear before in coarse teeth than in finer ones (the engagement ratio is going to be smaller).

As the others have pointed out, the teeth must also be strong (large) enough to stand up to bending stresses.
