What if I put a central plug? Like this?View attachment 60321

to look at:
- the thorns, i.e. the trees that carry the satellites, can not be planted in the hammered door for interference if you use the sintered (unconscious). It's gonna take a joke lip. Moreover you could dig a small helix on the long aber that does as a pivot of rotation of the satellites, to maintain the veil of lubricant.- the transmission of central motion does not make much sense with a plug put there so because each hammer holder has the solar integrated and must rotate but everything must be supportive to the stage that closes the tap.
- the ralles of all stages have an external diameter that is not much higher than the diameter greater than the teeth....so it could be subject to breakage and therefore not to transmit the necessary torque....necessary verification torsion of the crown.

without graphic analysis, how does it occur if the envelope tempting is complete or not?
but if it remains cut by electroerosion following this non-grain profile? do the bevels on the inner diameter and download?View attachment 60322How does it work?
I ask you because with internal teeth I don't have much to do except with the basics of the isb or similar.

I did not verify it, but I made it compute to the program of khk, I had doubts, I entered the data and my doubts proved to be founded.

Okay, like I did. on the practical side how would you cut profile if I had to denture it?

 

[PIETRO2002]

The sintered hammer holder may already have the integrated hammer plugs, as well as the integrated sun, and in front of the sun a cylindrical part that leads to centering, for assembly, this cylindrical part, must have a diameter greater than the outer diameter of the sun.

 

[meccanicamg]

certainly all integrated would be comfortable but a mold so costs a lot more and the male/female bounces for the sintered could give resistance problems...type to the base of the pins.

Detach it with traditional methods, i.e. with a rotary knife, it's not possible, as geometrically not feasible.
for a few pieces you could do for wire electroerosion, for large series you could think of a special drawing brow. . How much you cost me!

I agree with you, but maybe those who already have experience might even try!

very clear now. Thank you.

According to last indications and proposals, we have an output torque objective of the 4 stages of 100nm. Therefore, with the reduction reports indicated, we will obtain that the engine in maximum efficiency, with unit yields, can generate the following:
first stage (ok):second stage (ok):third stage (ok ma con b=9mm):fourth stage (ok ma con b=18 mm):a turkey to the bands of the two stages is necessary.
from here you have to start making the following reasons.

 

[PIETRO2002]

to clarify well the discourse of the 4° stage with crown z 51 and satellite z 17,
there are three checks to do:

primary theoretical interference
interference with pinion foot connection profile
Secondary theoretical interference

to avoid such interference a possible solution is, for the wheel to decrease the addendum and increase the dedendum.
for the pinion, increase the addendum and decrease the dedendum.

logically, as a result of these corrections, the sun will also have to be modified in order to have a correct ingration with its satellite.

I do not understand how according to the formula of lewis the teeth of the satellites are less resistant than those of the solar, should not be the opposite? I would understand if the calculations took into account that the solar doesn't have the teeth on the rise, or rather on the one hand it is solid to the carrier, which should give it greater resistance... but I don't think they take into account this.

the stages have all been realized in the same way, why only the last is problematic?
Why should there be interference here? (development method)
I read that the interference is created for the greater if you do not respect a minimum number of teeth, and with 17 I should be out of danger. . Right? (I guess not)

I'd like to send out some drawings next week to make samples and see what's coming out.

 

[Mattymecc]

Hello, about satellites I think they are subject to a larger pair of solar, but I'm not sure. As for the internal toothing of 51 teeth, I'm also sober, can't it be used because there is interference with satellites? Why can't you cut? or for some other reason? and primary and secondary interference and interference with pinion foot fitting profile how are they found? Thank you and excuse the intromission! ! !

I'm reading this very nice exposure and on page 27 starts talking about the correction x (profile shift) which he's talking about. Is it a little difficult to apply it, can someone help me?

 

[Mattymecc]

I studied it a bit and it should be applied when you have to change the whole of a couple of wheels, have you looked at the manual khk gear? is synthetic and very useful at a practical level, presents formulas directly without too many theoretical frills. . .

 

[PIETRO2002]

I recommend the book " practical manual of the gears " of henriot, if you want to really study the gears the two tomes always of henriot.
I don't know how to tell you to turn to someone who already has the skills, otherwise you're going to bang! guaranteed.

 

[Mattymecc]

I thank you for the advice, but to me more than the theory affects the most practical formulas and content to understand if the conditions you have said occur. Thanks again

I think it's important to understand the theory behind those formulas. It's a little like building a home without foundation. . .
complex problems cannot always be simplified. . or better you can do it after solving the complex!

 

[Mattymecc]

You're probably right, but all the theory behind it, in practice jumps out? to fully understand how profile shift works, interference etc... In the dentate wheels I agree that it is necessary to study in detail all the theory, but in the end the formulas are those. . .
a curiosity: all the theory about this topic is done at university? on the internet I did not find many dispenses on this topic. . .
p.s.: I also want not to know if I have the necessary mathematical skills to proceed with a study of this type...

I graduated from the technical institute last century and I learned things about books and working.
do not need complete or derived mathematical capabilities.
