dimensioning epicycloidal reducer

[PIETRO2002]

to be precise, the possible interferences, to which attention should be paid to the internal teeth are four:

1 primary theoretical interference.

2 interference with the pinion foot connection profile.

3 secondary theoretical interference.

4 possible interference due to the cutting process (tool diameter and cutting mode ).

the volume henriot, explains in detail the 4 cases.

excuse me if I interfere; I'm desperately looking on the web an easy way to determine what kind of relationship there is between incoming couple in the solar and outgoing couple... In the end, I would be interested in determining what is the pair of a screwdriver's spindle, known as the input (which should be the pair of a classic rc 775) scooter. the planetary reducer in the screwdrivers should be double if not erro and I think they change things.

1) Have you read the rules? No.
2) have you introduced yourself? No.
3) you are a student and not an over50 so you are born in technology, so use the "search" command
4) We talked a lot about it on the forum, sites where to look and then put our heads on
5) if you want the ready jelly you have wrong place
6) returning to your question poorly mail, do you have to determine the reduction ratio of the reducer? Let me give you a ride out and count how many he's made in....you found the reduction report. or remove it and count your teeth. know how much torque brings an epicycloidal....it did the project, know materials and treatments as well as exact geometry. if instead you agree to have the curves of the original motor mounted and determine the reduction ratio and make the calculation of torque multiplied by the reduction ratio.... is a different thing.

Are you doing a college project? can be interesting things....if you start with the right foot....but you can always fix it.

 

[meccanicamg]

so much to say looking is this....with reduction ratio 14,4.or we go on another opening the link says report 12,6

I press that the uselessness of the "search" button is equivalent to your first part of answer, while the second part does not consider it because written with a syntax and a grammar that far away from the Italian language that we all or at least know.
to answer you: no I did not introduce myself and no I did not read the instructions; It's not like I opened a new post or did who knows what. I continued an open one a short time ago, limiting myself to apologize for being introduced and above all asking (while answering is courtesy). Now since you've made me waste only time reading what you wrote unless you really want to help me understand what I'm asking, I tell you to spare yourself your arrogance for the many things that reserve your life and then to shut up. it is not that if you wrote senior then you can afford to treat people like this; Look at you in the mirror in the morning and before you write some questions if you ever tell her four eyes. Now remove me, I will ask others.
Hello keyboard lion!

Sorry, but where did you learn education? I knocked in a house that isn't yours to ask for help, and then you treat a person that he's given and for so long for this forum!

in the end I would be interested in determining what is the pair of a screwdriver spindle, known the input (which should be the pair of a classic rc 775

the torque supplied by the spindle is equal to the torque of the motor multiplied by the reduction ratio of the two stages of the epicycleidal and multiplied also by an indicative performance of the cinematism of 0.9.
the nominal torque of the engine, the torque blocked and the number of turns according to the power voltage, are generally provided by the engine manufacturer with tables like the one I attach. you must then consider that generally the screwdrivers have the double screwdriver function (speed 100-250 rpm) - drill (speed 1000-1600 rpm) that can be activated by a selector and in both there is also the possibility to change the speed with a potentiometer controlled by the screwdriver button.

Now since you've made me waste only time reading what you wrote unless you really want to help me understand what I'm asking, I tell you to spare yourself your arrogance for the many things that reserve your life and then to shut up. it is not that if you wrote senior then you can afford to treat people like this; Look at you in the mirror in the morning and before you write some questions if you ever tell her four eyes.

I'm sorry, it's not my intention to repress you, but I would just like to point out that your reaction was a bit excessive and in the context of your professional life future attitudes like this could give you closures and failure to cooperate by those who should grow professionally.

I don't know why but you think the forum is a whatsapp chat and who knows why, to sign up there is a simple regulation to read and some don't even deserve to use good education. Why do you need a regulation to understand that you have to submit?

I used google and did a search "epicycloidal gearbox" and I came out different types, from which I discovered that the reduction ratio is worth 12 to 15.

If I know the engine, I know his couple. dixan calculator and I find the couple to the spindle.

for me it was over here, resolved and complete.

You write that you're a student. Good. If you're in high school, it can be. If you're a future engineer... I see you're supposed to be 25 for deduction, I mean, it's not okay with your behavior.
If you give us information about your school preparation, we can calibrate the information to give you.

from my post, I told you that the reduction ratio of a reducer is obtained experimentally by counting how many turn in to make it an outgoing one. If you don't have the construction project in your hand and if you don't remove the reducer, you don't have any other ways. But I see you don't understand this information, because you've been through it.

then I told you that if you know the electrical characteristics of the engine...you write that should be the pair of a classic scooter rc 775, means that you are sufficiently prepared to know plate data, engine curve and maximum torque. If you're not doing a google search and you'll find it, as long as it's not that hard.

torque an output = torque multiplied by the reduction ratio multiplied by the output of the reducer. but I took this for granted because an ing or a peritum knows that the c2=c1*i*k....but maybe you're not a student who followed technical path. If you have followed the linguistics or other non-technical paths, we must explain several things to you at the base (so pair/current/couple/calculum powers/what a reducer needs....).

but you don't tell us and we have to guess.

You need help and you're not able to give the information to those who should give you a hand that you need... not me.

less polemics and more education.
Now in your next post we should see the results numbers of what you asked.

unless we know what you're asking.

if you want to know instead how an epicloidal reducer works is explained on khk gear, but it is written in English. google has the translator if you have any words you don't know.

if you do not like the command look for this forum, you can go to google and type in addition to your search key also the word cad3d.it. This way you can filter images and discussions related to your search.

is at the base of the internet knowing how to search. Actually, when there were books, he learned to search. Now inside the coin....out of can.

I am sorry if I introduce myself, I am looking for information for dimensionalization from 0 of an epicclidal rotism to draft a technical report (work from high schools).
on textbooks these rotisms are just mentioned and their sizing is not reported.
the point is to know if you have sources to consult that you can advise me (I don't want to bother you to explain it to me also because reading previous comments I understand that this is a very vast topic).

 

[PIETRO2002]

As already reported in a previous post of this discussion, a complete book on epicloidal gearboxes is: "planetary gear trains" di arnaudov e karaivanov di taylor&francis group,

I like your approach.
The book that recommended you pietro is a complete book even though I think it might be a bit tiring approach.
definitely it is good that you start by understanding the basics of epicloid systems. for this I recommend you look on the site khk gear the section concerning the epicicloidal reducer, the reduction report, the trains etc.
another book to be used is the niemann volume ii. other book is the free one of the bonfiglioli motor.

for this I provide you with some links, discussions made on the forum that lead to particular sources or reasoning.
qui.qui.qui.qui.

 

[meccanicamg]

the reference to khk gear are at least these two pages:qui e qui.

on behalf of my study group we praise you

hi, I would like to know, since the books of niemann are introvabile, if in the epicloidal rotisms the crown (fix) is to be sized according to some method or to find the number of teeth it is enough to refer to the transmission report; same question for satellite wheels.
Thank you.

Thank you.

the number of teeth is determined by the consistency formulas that are also indicated on khk gear.
solar, satellites and crown cannot have an arbitrary number of teeth.
