I was confused by this so I asked an expert...

"If the large tooth number is evenly divisible by the small tooth number, then the same teeth will always contact each other. So if one tooth gets
slightly damaged, it will continuously wear on the same mating teeth and wear out sooner. If the numbers are not evenly divisible, then the damaged tooth will mate with every other tooth after a certain number of revolutions. Thus the wear will be spread out across the entire gear. So, it does not really have to be odd and even - just not evenly divisible. However, in our applications, this is irrelevant because we do not expect the gear mates to last for many years of constant use. A much bigger consideration is to properly design the gears for size and materials based on the loads required to be carried.

Is this what the criteria for the odd ratio is meant to achive?
