orthogonal reducer with creo parametric

the gear tooth is an evolving profile to gear and transmit the bike. if you look in the previous posts I attached you a zip file with three gears in step format with the real profile of manufacture. So you're horrified and you know what I'm talking about. . .especially of the fact that the small gear from 11 teeth if it is built "standard", i.e. without making profile correction, is carved at the base and loses a lot of its ability to convey the pair with the big wheel.
 
Unfortunately, I had problems and had to leave everything for almost a month: (I finally start this blessed project. I attach the exit shaft (only part so far modeled). What do you think? Are they on the right path?Immagine.webp
 
As for the teeth, however, the prof said that we can approximate them with trapezoids ..thanks however for the curves :)
 
I'd say we're almost entirely on the first piece, that is, on the tree. lack adequate bevel and fittings. Maybe especially bevelous to slip the gear easily.
then look if there are no other jobs like seeger or threads or similar to do to keep the gear in place.
 
thanks..but in tabs 29 and 28 what are the "diagonal" ones? Isn't it the classic tabs?

is the way to represent the tabs that you see in the section should not have the sampling and therefore, being simple geometries represented by rectangles, in a drawing together they could "spark". bearings can also be represented schematically with diagonals. If you have, you should have, a vademecum will see the representations of what is said
 
Thanks :) But the inner diameter of the crown must be the same diameter as the shaft with which it will have to mate? or are there any tolerances to be respected?
 
for the last question I solved alone.. now I ask you: I have to do the fir 8 as if it were the entrance tree, how would you size it? And why?

how and where do you recommend to smooth and round?
 
hi guys are always me :) thanks to your precious help I arrived in the modeling in the situation I attach you (excluding the box that not yet model). Now I ask you: what and why would you add for bearing mounting? What else is missing (beyond the box)? I thank you in advance hoping you can be once again a great help :)

missing that something that does not move bearings and gears where it serves.
look well the explosive and the various drawings that find the missing pieces.
 
If I were you I would take a look at the discarded jaw pozza vol.3 or the skf training notebooks for how to block axial shift of a tree :)
 
hello to all:) First of all I thank you for the help in the past!! in September I didn't have time to deliver this famous project and so here I am again:) would someone know how to give me some tips on how to make the box?
 
electrowelded in two half then you will have the housings of the bearings means in the case under and above.
everything with sheet of 10 mm thick and where you have the thick shanks bearings to accommodate seals and bearings.
If you are looking for google you will find several photos for inspiration.
then take oil cap, drain cap and level spy... all elesa.
then check for heat exchange and see if you need to change sheet thickness, add fins or fans.
then a fem to see if it bends.
 
Thank you.. but how do you choose a oil? the prof told us to download the model from the site tss elleborg but there are very many components and I do not understand what it does to my case also because they are called in English. Would you know what they call in English what they do for me? and to choose the right measure of what should I take into account? only internal diameter oil = shaft diameter?
 
other questions:
- What's that and what's a rubber hat for?
- What's that, and what's a saddle for?
I guarantee that I have not treated these elements in class. with this I absolutely do not want to criticize the prof but I tried not to pass as the unproven that cares during the lessons and then try to do the miracles x the exam. .
 
Immagine.webpthanks to your generous help I have come here.
do you notice particular errors or notices I could make?
What do I have to add in addition to the semi-casses and rubber caps?
What are they, what are they for, how do they size and where should the rubber caps be placed?
 
Immagine.webpI came here spulciating here and among the old discussions of the forum (fantasy sets).
can we say that in addition to the case only the organs are missing for fixing the input bearings?
I read from the explosive that these organs are straight and seeger ring right? would you explain to me how they act, where to place them and what size to make them?
Thanks again, you guys are saving me with your valuable help both on this discussion and in the previous ones:)
 
Immagine.webpwaiting to figure out how to fix the bearings I made the box. What do you say? too simple?
