How to Set up a Gear FEA Analysis in ANSYS using Joints and Remote Displacements

I think the reason for obtaining low stress values is that the contact forces (resulting from the contact stress) are not meant to overcome any opposing force from the slave gear. The boundary conditions given would result in free motion of the slave gear while being pushed at the point of contact by the master gear.
I would model this problem with Cylindrical Supports at the center of each shaft, Remote Displacement at the center of the master gear (to rotate it by 12 degrees), and a moment of arbitrary value at the center of the slave gear (representing the opposing moment which might be a result of misalignments or friction between shaft and gear).
I have not tried this idea out, but I think it would result in more realistic stress values.

Please sir send me the 3d model

Great 👏👏sir
Can you please tell which material is used for gear as well pinion.

how to rotate the gears from 0 to say 20 degree in analysis and plot the graph between angle of rotation and mesh stiffness?

How can we determined angular displacements i. e. if one gear is rotated by 1 degree than due to deformation the other gear rotated by greater than 1 degree. Angular deformation = theta2-theta1 where theta1 is input gear rotation angle and theta2 is output gear rotation

Hey can you plss upload your solidworks file
Or can you plss make a video on how to make a gear on solid works
