ungrained wheels

[CristianT]

as he said @meccanicamg It's a problem that has people who build epicloid ruotisms. I remember studying how to do it at university, but many years have passed and I have to finish urgent work. try to google the theoretical tracing and then return it to your real case.

I've looked everywhere, I'll keep trying.

observing the system well the risk is there... and as said the ideal would be that you only fill it with a wheel above and with a wheel below.

Now the situation is like the figure, I just wanted to figure out what's wrong with me, thank you anyway.

 

[CristianT]

If there is no technical reason why the gears should be all in cascading socket, you can predict the b series on the left on a different plane increasing the thickness of the gears to, so that you only integrate on the right gears (motor side). the rotations and synchronisms of the system do not change and avoid interference problems between the teeth.

the link to the discussion of epicicloidali on the forum are qui....qui....
while the manual khh is qui.
certainly the idea of having double-ended gears and working only one gear with one conduit I would say that is the optimal condition.
we build a patented machine that has practically a system of gears that close on themselves. it is essential to have some gears to today nterasse variable to manage the game of ungracing.
important mixing with related organs.
Surely it will be necessary that all the teeth are rectified and that they have enough game but it is not enough because it is almost impossible that you can get everything in contact....super lappature and very exact geometries.

I will read carefully the links you posted to me, thank you.
I had thought of course for the variable intersection, asking to understand if from a theoretical point of view I miss something.
Unfortunately the situation did not come to create for my "merit" and therefore I find myself looking for solutions.
Thank you.

if c has number of teeth different from to you will have problems of "phase" between the two wheels b and c.
in fact the wheels b are between them in phase thanks to a.
If there is a number of teeth different from then you will not be able to have the right mix because with a primitive of c different from that of a you will not be able to respect the angle step of the wheel c since you have two tangency points and a finite number of teeth to "make us stand".....the only possible solution assigned a module is that c=a.
This problem does not arise with single gear cascading trains but in your case it becomes fundamental.
greetings

the problem came to create by putting a c=a wheel, but you have problems.
Can it be that the problem was a number of teeth of 29? If there was a wheel with a tooth number 28, would you have solved this?
for the rest the situation is like that of figure, I would not have put the wheel c in that position, but patience now.
Thank you.

search for "simultaneos gear meshing", some stuff comes out.

In fact, in my case the condition dictated by khh is not satisfied.
already is a starting point, thank you.

At this point, to make the system work, in my opinion you have to stop the seat of the wheel c, create another seat, so make to work the new wheel c as we said in some previous post. the wheel will have to gear with only one gear of the first group and with only one gear of the second group. Maybe someone has a better idea. . .

I know. the solution is to change the position excluding a scratch or to put a "correct" wheel.
But first I wanted to understand the hippo, I asked.
even if of the condition dictated by khh I did not find trace elsewhere.
If you have other information about the origin of this formula, I would be happy.
Thanks again to everyone.

you can look for on the book written by trivial gearboxes that is called the gearbox manual. is free and is freely online. Take a look at the stuff.

hi mechanics mg there is something that does not return to me already from the first two toothed wheels, to turn in that sense the first wheel b if the m is the drive and turns in anticlockwise the ingrain and makes it rotate in the opposite direction

You're right turning like the black arrow....sorry

from my point of view,
if the wheels that gear between them have the same module, and the interaxes are correct, the theory is respected. At this point I think that if there are any mounting problems, we must investigate the construction, that the problem may be in a wrong execution.
This is obvious, but not obvious.

dissent, look at the theory in post 27.

If it wasn't so any gear would grow....but it's not like that.
Put a z=200 on it, and tell me where it is.
