drawing. extraction of the particular tree

[Domenapoletano]

Good evening, guys.
in this exercise, in disegmenting the tree, do I have to draw it including of threaded shank at the ends?

I thought that there must be codons to allow the screwing of the two dice...

Or is it enough that you draw the tree with its quarries? in practice draw only the part of the tree that is inside the organ (up to the two fields of the belt 16 and 8)

Do you think it is necessary that you draw also the sticks?

Thank you.

Imagine disassembling that mechanism and extracting materially the tree you need to draw...the shanks are part of the tree or are they distinct details? Of course the codons are part of all the effects of the tree, so they must be drawn.

tabs (and non-key) are usually unified elements and are not part of the tree, so they should not be drawn, while the venues should be drawn.

Thank you nino, you were very clear... That's right. how does a small tongue stand out from a key, starting from the design?
the stick is like a tab, only that has one face tilted from one end to the other.

Obviously it also changes their operation because their installation is different and the key also prevents the translation.

but from the design?
Thank you.

the tongue has air in its upper face to the wall of the hub.
Keys have air on the sides.

both are unified and by trade so they should not be drawn.

not always; what differentiates them and the type of assembly.

please next time attach the correctly rotated design so you can read it without having to download it.

about tabs and keystrokes, some pdf:This isThis isif you do a targeted research (learn to do research with logical operators) you find so much material in the forum

in truth even on every dignified technical drawing book are explained. once the internet did not exist, it was used what is called "book" and "manual of the designer".
