technical drawing exercises

[gspshep01]

Hello everyone, my name is christian and I am a student of industrial engineering and I am preparing the technical drawing exam, I wanted to ask, being new of the forum, if you could give me a hand to understand if I can correctly interpret assiemi and extract the specific component, since the exam is precisely on this, I would start with a simple reducer of parallel axes, I would make the distinct components and I would like if you could correct me some error of interpretation.
I would like to say that mine is a relatively short examination as the duration of the course being 6 cfu so many arguments have been dealt with without dwelling too much, which in my opinion leaves too much room for interpretation on the study to be done.

thanks in advance

such reductions have already been treated abundantly and I do not exclude that the same as you have attached, with relative distinction, be already present in the forum

(ii) dentate ? why is there a tear and is not dissected normally?

because the trees and the wheels are not separated; the 4 is dissected otherwise it would not have been understood that it was separated from the tree

8) do not understand whether it refers to the plate or that black tract that could be a thickness?

gasket

10)ring? I think it serves as a seal?

gasket

13)spessor?

gasket

15)ring

gasket: equals position 10

16)distantial?

si

26) cylindrical rod that acts as a pin?

centering plug for precision coupling of the two semicarcases

27)can be an element that serves to insert lubricant?

oil cap

28)

oil level control cap

29) screw with seal?

oil discharge cap

Esercitazione di costruzione di macchine - riduttore

Ciao a tutti, per il corso di costruzione c'è stato assegnato il dimensionamento di un riduttore (come tradizione), è quasi giunta la data di consegna. Ho preparato un disegno dell'assieme ma ho dei dubbi e ho pensato di "condividerli": 1) Vorrei aggiungere delle spine di centraggio, dove le...

Riduttore ad assi parallelo distinta componenti

mi servirebbe la distinta dei componenti

in the last link I put, where the reducer is exactly the same with the same bubble. the positions 8 and 11 are indicated peelable thickness, but to me it convinces little; I don't think it makes sense to use a thickness in that situation where the bearing is stuck, and it must be blocked, from the flange collar, more likely to be, in my opinion, a flat seal

thanks to the help, I will listen to the advice and I will look in the forum before creating new discussions

another beautiful pdf with the representation and conventions of the gears (I save this myself) and that corrects my cow of point 3.
the trees do not dissect and therefore to highlight unseen parts the tear section is used; the dentate wheels are separated like any wheel, excluding the teeth that must always be represented nothttps://www.unisalento.it/documents/20152/200588/trasmissioni+meccaniche.pdf

thank you for the help and availability, could you please explain to me why the pinnacle was cut off? Is it because it's like a tree?

the pinion is an integral part of the tree and as such should be considered; so to show the mounting with the coupled wheel you have to do a tear section

Thank you very much and good day

I am doing this exercise and I was trying as last time to write the distinct components but I was doubtful, first of all I cannot understand the function of the piece, the distinct one:
1)external body
2)perone
(3)vite
4)close ring
5) headless screws
6) headless screw 2
7)Norship?

I thought that this threaded pin could be inserted from the bottom and locked first with a headless screw in the indentation, then screwed on the top that I called the closing ring, but I don't understand what the 6 component needs to be a locked screw on a seal?

Thanks for the help and good evening

 

[gspshep01]

Could the 5 be an antisvitation?

 

[MassiVonWeizen]

small correction before looking at it with calm:
those that call screws without head are defined grains; your term is not wrong, but with the other it is easier to find matches and norms.
the 3 is not correct to define it screw as the fact that it has a threaded part does not indicate it as such; would be more correct to call it support (tailed swallow)
of course the name that is given to the components are indicative and call them in one way or another similar changes little; in the mounting design must be indicated drawing number and quantity

 

[MassiVonWeizen]

position 7 is not a garrison, but an anti-slip (or equivalent) gommino that allows the friction of the wreath with the support. Now that you know this try to imagine what happens when you rotate the wreath

 

[MassiVonWeizen]

errata corrige: the seat of the support is not a tail of swallow, but a simple v

particular 6 is a flat grain in accordance with turned section ....serve to block the rotation of the threaded wreath. Also in front of the grain there is a small bronze pastel to not affect the fillet.

flat grain turned to normal, particular 5 serves as anti rotation of the central handgun. ..behind in a quarry.

@gspshep01, but do your exercises just give names to the pallinated elements?

 

[gspshep01]

thanks to all of the answers, as soon as I reopen the pc I try to respond better, my exercises are in extracting the component and making a sketch quoted, but for now I am trying to get used to the eye to immediately recognize the component so as to understand at least what I am drawing
