Hello guys, can anyone help me to solve my problem in spiral bevel gear simulation, I have got the results but the results are not in accordance with the theory, it could be that I am wrong in the input on ansys, please help me, guys, if it works, I will give you a reward, thank you,

What theory did you use and what did it show?
What results did you get from Ansys?

[dhebynanda97]

Can we discuss with WA bro??

[peteroznewman]

No bro, we discuss it right here.

[dhebynanda97]

okay bro, so this is related to my final project problem, I solved a problem related to the broken teeth in the spiral bevel gear, here I see the tension in the gear which will later be related to the result of broken teeth in the gear, can you help me bro??

[peteroznewman]

Okay, since you have solved a problem related to the broken teeth in the spiral bevel gear, reply with details how you solved that problem. What were the results?

[dhebynanda97]

I'm looking for the maximum stress that occurs in the gear teeth, but the results I get are not in accordance with the formula I used as validation, am I wrong in inputting what is on ansys or what, that's my problem bro, can you help me bro?

[peteroznewman]

It's hard to help you if you don't provide any details.
Show the formula you used as validation and the result you got.
Show the model you used and the results you got.

sorry bro, I just opened the discussion forum bro, here I try to detail my simulation, please help me bro, thank you,

[peteroznewman]

Thanks for the photos bro.

See how they don't model a complete 360 degree piece of the gear, but maybe only a 30 degree slice. Pay attention to the size of the elements, see how small they are at the contact point. This is where you need to go to get a better agreement between your model and the hand calculation.

hello bro,, thank you for the solution you gave bro, after I saw and understood the solution you gave, I didn't find the same thing related to the problem I was experiencing, now I want to ask about the boundary conditions and contacts that I input in my simulation whether is it right or what bro?? thanks bro,

Hallo Bro,,, After I saw the post from 3enrique, how do I change the results obtained to be clearer like this bro? thanks bro

[peteroznewman]

Don't model a complete 360 degree piece of the gear, but maybe only a 30 degree slice. Don't use any contacts. In CAD, unite the disk with the teeth, unite the shaft with the teeth. Then you will have only 2 bodies to mesh. Pay attention to the size of the elements, see how small they are at the contact point.

ok thanks broo, After I saw the post from 3enrique, how do I change the results obtained to be clearer like this bro? thanks bro
