I looked at the force diagram that has been attached but I have my own doubts. A gear has three forces that needs to be equated to its supports.
1)Tangential force: This force acts on the surface of the gear and at the meshing point. This force is always against the direction of rotation of...
Fit is based on the surface area around the material that comes in contact with the mating part. The nearest thing to calculate force for press fit can be made be converting the available area aound the rectangular component and then finding the diameter equivalent in order to use in the Force...
