Forces on Rollers 1

[knt823]

Looking for help calculating the forces on the diagram. The large cylinder will be able to rotate both clockwise and counterclockwise. The smaller cylinder will be supported through its center axis. I want to figure out the force that will be on the smaller cylinder.

Is there a second support roller? If not, good luck!

Yes there is a second support roller.

My experiences with roller supports indicate

1. use crowned rollers
2. use as large of support rollers as can fit / and fit your budget
3. depending on materials for the large diameter, use the track factor reductions, and consider hardfacing if there will be many rotations
4. assume symmetry to conduct your analysis, and then it is just a trig problem
5. have a look at the track capacity section of attached
