steel choice for toothed wheels and transmission shafts

[svitowski]

good morning, I should make the choice of the material for couplings of dense wheels and the respective trees on which they are mounted. After calculations I obtained maximum wear stress values of 1200 n/mm^2 for the first coupling and 1268 n/mm^2 for the second. with regard to minimum brinell hardness the values are 490 and 517. I had thought about the use of a 34crnimo6 steel hardened to the flame or induction, how would it be optimal or there would be other steels more suitable to the case in question?

for toothed wheels I recommend a type cementing steel 18niculum5 (or similar), while for the trees you could use a rectified steel like what you mentioned in your post (34crnimo6) or 39nicrmo3 or similar materials.

thanks, however two wheels are made of piece on the trees so I am bound to choose the same steel for both wheels and for the trees, so do I recommend to choose a cementing steel like what you indicated?

is a topic already discussed in the forum, did you do a research?

I found a similar discussion and chose steel using tables that had been forwarded to it, but I wanted to have a confirmation regarding the choice

first I would say that in addition to looking for the various posts where I reported the tables of iso 6336-5 you will have to choose what standard to use because depending on it, you will use this table or other tables and the relative coefficients to use.
If you use iso6336 then you can easily calculate the characteristics with the table and from there choose the material.qui.qui.qui.
above all qui.

and then looking.... There's more.

All right, thank you very much
