Are these fits sufficient to manufacture and assemble this spherical joint with its bracket? Is there any mistakes in the fits
I have chosen both H7/k6 and H7/g6
Accepted answer
in my opinion the part 1 is overdimensioned
the diameter 36.10 and the width 20 of the part and the dimension 6 with their general tolerances (which are missing) conflict with the diameter tolerances for dia 42 and dia 30.06 - some of them should be changed to reference dimensions.
Also dia 36.1 should be marked S dia 36 (S..spherical) and placed at section B-B.
Section A-A is unnecessary
Part 2 similar

Agree with AnMay. But I would comment further: What would seem to matter most on these parts is the spherical diameters. That‘s what needs to be specifically dimensioned and toleranced. And like AnMay said, those dimensions need to be placed on a view that shows the profile of that sphere. The length of the parts has no implied tolerance. Although some shops have tolerance standards that aren’t always listed on the prints. Even so, in spite of the tight tolerance given on the diameter at the ends of the spherical section, a length variation reflected against that tight tolerance would result in significant diametrical variation of the actual sphere. Well outside the limits of the fits you quoted. Yes it’s over dimensioned but you don’t even have the dimensions done in a way that effectively control the significant aspects of the part.
With all that said. The parts could be manufactured, but it would be impossible to assemble them together.
Is that true? or another modification is needed?
