I am an engineer working with a planetary gearbox reduction that needs to lie in the 18-20:1 reduction range.
I am limited strictly in the diameter of the part, and will be using two stages in a fixed ring configuration.
I have determined that there are about 8 arrangements that will fit my requirement for a common ring gear.
However, I am having difficulty making an educated choice on what to use.
I'd like to lower noise as much as possible through good contact. The box is loaded on either side of the tooth flank through its motion depending on the point of travel, so even approach and recess are ideal.
These are all formed gears.
My parameters are my tooth numbers. The module floats slightly depending on the ring gear tooth numbers.
I seem to have difficulty keeping the sliding ratio down when I attempt to bring the contact ratios into reasonable ranges.
Given the fixed OD, is it better to go toward a smaller or higher module to improve my operating parameters?
