epicyclidal reducer

1590681492095.webpthere will certainly be around gears with b/m ratio greater than 20, but I think it is something definitely esoteric... If you have some examples of gears with the band so extreme, I would be curious to see it.
 
in many particular applications, paper sector and also in other sectors they make sprockets with 2 to 4 module with 50/50 teeth and the widths of these teeth are really very wide.
It's not that weird. the important is used adequate bearings and that the shaft is very rigid.
 
from the book theory/calculum/design - new techniques There is a beautiful table ....and I also found directions for speed above 3000rpm, so b/m greater than 40.

sorry if I interrupt but as we have the solar to with z=14 and m=1,25 then primitive diameter 17,5mm, which diameter will have its tree since we still have 4000rpm and 36nm that is not little..... Is a tree so small enough?? ? ?
Thank you.
 
solar gear must be integral to the input shaft; 36nm are manageable for that size.

take a round larger than the gear head diameter and return the bearings' jokes and the transmission hub. then put the piece on the toothpick and cut the teeth from the trunk.
the diameter just by side will be something smaller than the bottom diameter of the gear.

It will look like this:Screenshot_20200529_162119.webpthen maybe you can use a "millerighe" instead of a tab.

Thank you very much.
 
but I have a doubt, the sun from z14, module 1.25, width 50 mm, resists to 36 nm at 4000 rpm?

I would do:

propeller 15°
band 30 mm
module 1.75

In this way, I realize that you are not in the outer diameter imposed by 100 mm, but if we do not want to break the reducer shortly.. :

we can not exceed 100 external diameter.
also module 1.5 is too much.
