Full recess planetary gear set
Full recess planetary gear set
(OP)
Hello all,
I have read lots of informations on books and on internet on simple planetary gears set, and I don't understand the "design rule" on the approach and recess action.
In the standard AGMA 6023 B06, I can read that the approach action has to be equal to the recess action in all meshes in order to be the most efficient, And in this forum, I found some topics on Full recess action in planetary gears.
Someone can explain to me what is the most efficient rule that I have to follow?
For info I am designing an epicyclic gear set with
ratio : 4.3
sun gear : 18
planetary : 21
ring : 60
modulus : 0.6
Input : sun
Output : planet carrier
input speed : 15000 RPM
input torque : 0.1Nm
thank you for your help

and 25 percent short on the ring gear. The center distances are not
standard. Experiment with other percentage to see different results.

I'm not sure to understand your post, Are you talking about the percentage of the recess length in each meshes?
RE: Full recess planetary gear set
Some folks do not modify the planets and simply modify the sun and ring using the
long and short addendum on the two respectively. You can use higher percentages but make certain you do not have a pointed tooth on the sun. This limits the percentage amount that you can apply.

I will try your ideas and i will let you know the results.
the last test with 50%/50% appraoch/recess at each meshes work quite well
