thanks Bestwrench I agree with your observations everything on the assembly has been checked for shear, bending, tear-out and bearing. this shaft was a little bit of a concern since i am designing to API 8c spec and factor of safety needs to be 2.9 and if i was to consider bending on the...
Bob i agree with you on the axial load part but i will have to disagree with you on "It doesn't matter if there is radial clearance between the bolt and the end plate, bosses or block" if you draw a deflection curve of the shaft you will see that minimizing deflection will minimize stress basic...
Tmoose thx for the input but i dont need help calculating the bending stress I am debating whether bending exists by modeling the shaft as simply supported. this question should be possible to answer without dimensions. also as for changing the design not practical.. the geometry must look like...
There is no doubt in my mind that the shaft sees bending but the question is how much! The reason I beleive that shear would be the design constraint is because in order for the shaft to bend the block, bosses and plates would also need to bend due to the tights tolerances and taking those...
Im hoping someone can help me with a design im currently working on.
I am designing a shaft to take 200 Tons (400Kips) now the dilemna is that do i consider the shaft to be in pure shear or do i treat it as simply supported or maybe fixed-fixed end condition?
my initial calcs considered...
