size reducer case

[febro6]

hello to everyone, I sized a reducer and found everything I need, I just miss the size of the external case and I don't even know where to start.
Can you tell me a way to solve it?
Thank you.

Hi.
First of all, what do you mean, I found everything I need?
I imagine the kinematic chain that will have to "do the reduction of motion, and therefore you have minimal dimensions.
you definitely have the type and size of the supports (cuscinets), you decided how this reducer should be produced (set of single piece plates or a fusion for large series) and then define a bit the layout of what you need.
you will need a system to adjust mounting the bearings in place (bar flanges) etc.
depends on me how complex you want to build it and then from them you start to attack piece by piece.
do the checks once you have proportioned the whole, check the finished elements for the thermal check structure to assess whether the transmission oil is properly cooled.
I suggest you make a simple pattern of the transmission you have to wreck, look at the old posts and you will see that here you will find valid tips.
ps if I can, detailed questions correspond detailed answers

Good job
Michael

with "I found everything I needed" I meant exactly what you wrote (the cinematic chain, bearings, force, iningombri.. ).
I needed to know what theory to use to size the reducer box.
cmq I tried to use the theory of the plates stuck on the contour, I got an indicative thickness and now I verify it to the finite elements.
thanks for the answer

Good day
