improve in technical design

[Oscarinho]

Good morning, I wanted to ask if you would recommend me books, websites or even videos to improve in technical design.
I wanted to deepen the part of the reading of the drawing, and go to learn how to improve it.
I am already watching many videos on youtube to deepen the world of mechanics (e.g. tooth wheels, bearings etc.), but I struggle to find mechanical designs medium or more difficult.
Thank you if you can give me some inspiration, thank you.

for drawings there is material in resources, for books there are dozens of discussions with suggestions and indications.

Bye!
then I suggest you download from google the industrial technical drawing slides of alessandro carandina.
then on the forum site there are several resources, for example try to search: links to drawings for exercise.
regarding books I possess the trilogy of mechanical drawing of pozza, manfè & discarded and the vademecum for designers and technicians of baldassini. are great books however consider that even for free you can find on the web slides and more than complete dispenses.
As far as the exercises rejuvenate, I recommend that you learn well the basic standards of the mechanical design (although at first they seem abstract are really fundamental) and the operation of the components and systems of sealing/fixing/connection main among which:
- bearings with their mountings & blockings (I suggest you also consult the skf bearing manual)
- toothed wheels
- pulleys and belts
- axes and trees
- gearboxes
- tabs, keystrokes & profiles
- screws, pins, thorns
- springs
- welding
- joints
- brakes & clutches
- triggers.
- sealing elements ( here is an interesting video

)
- other things that I don't think of now
As for complex assemblies it is not easy to find many, there are many axiemes of gearboxes on the web but for other material you have to spray many texts both of mechanical design and also machine constructions!

Thank you very kind
from today I put myself to work
Good day

Sorry the question: Do you want to make technical drawing (yet) with 2d software or own 3d software?

I ask this question because the methodologies are a different one.

hi, I mainly use autocad and inventor (self-taught), but I have to make most of the free hand drawings on paper.
what I wanted to ask was not this, but how to have a better knowledge of the elements such as bearings etc. and maybe to change components to improve the structure.
How did you tell me?

then your problem is not how to improve the designer but how to become a designer.
I recommend the three volumes of niemann. you need to know how to calculate the various elements and how they work, how long they last, whether it is better this or that.

also this resource can be useful.

on the internet there are also video lessons of materials such as machine construction, applied mechanics, drawing etc etc., not only at university level that perhaps are too complex, but also at technical institute level since some professors, during the lockdown, recorded their videos and then put on the net.

I'll send you some overalls I saved on the pc

an excellent exercise that you could do is to make the drafting of the basic or bill of material in English (also simplified given the educational purpose) of some simple complexes like those reducing 01 and 02. then make a list of both commercial components (closes, seals, screws etc.) and those made ad hoc like trees, dentate wheels etc.
of these components also tries to understand why they were chosen: for example if I have axial loads that bearings can I use? or if you see a conical wheel you wonder what kind of efforts you charge on the tree? make a choice of the catalog tab by inventing data as a shaft diameter (e.g. 20 mm), a power to transmit (5 kw) and a certain angle speed (1500 rpm).
for the most articulate complexes instead tries to understand their functioning and to recognize as many elements as possible and maybe make drawings of some of these components. for example try to draw a tree, a helical spring with all the quotas and info necessary for its manufacture

and there are examples in the forum

Good afternoon, I apologize if I didn't respond but I didn't get notifications! !
thank you all for the good advice
I have already started from Friday to see videos on youtube and find some book/pdf present on the internet.
in these evenings I also begin with the complexes
Thanks again and good evening
