exercise - drawing of machines (reducer)

Tell me if the mating with the scene is fine
to the right the channel I made it finish first

 

[meccanicamg]

in the exit shaft I put the braces on the right of the wheel and on the left I have to put a radial bearing to compensate for the spins
is it correct?

to prevent that I still do not have the right knowledge to choose the bearings.

that I remember the exit tree is up and down no right and left

and on the other side what is there? You can't do a groove with a cylindrical part of the same diameter on one side... The wheel must be threaded.

then high I put a conical roller bearing
down one ball and double effect braces

check that the double brace can hold radial load, otherwise both bearings should be revised. look on skf!!

Guy sewing!

ah you put the short spacer sticking to the c...lo :finger: Okay.

I didn't understand that.
and however the double-acting braces cannot hold radial load.

is Italian. If it's a biaxial brace, I don't know how much it is to keep radial. if the tree you keep driving it only behind with a conical and front only axial you have that the tree runs out on the first half of a tree

correct me if I'm wrong!

 

[meccanicamg]

Okay, but then you don't need the tilted roller bearing anymore. There's that thing that costs a patrimony and it just doesn't help.

ahahahh and what do I put in his place?
another radial ball?

Don't you think it's better?

and then the trick lies in balancing the axial and radial forces or according to the function that the shaft will have to perform, are the suitable bearings chosen?(from the point of view of the loads).

Don't you think it's better?

I say yes!

bearings that are on the exit shaft do not necessarily have to be different. for example I put two simple radial ball bearings, so much the whole axial load is "absorbed" by the braid.

and you didn't lock the outer ball bearing tracks, with the right case? ?

No, only the inner ring of the bearings blocked. external ones are naturally in their home, but they are not blocked axially.

 

[meccanicamg]

No, only the inner ring of the bearings blocked. external ones are naturally in their home, but they are not blocked axially.

if it were not so during the thermal expansion of the shaft, this stretches and goes to axially preload the radial bearings bringing them early to the end of their life. only the biaxial bearing must bear such load.

Tell me what brake this reducer is and where am I wrong? ?
Thank you.
