Question

a shaft in hole assembly uses the tolerance symbol of 90H7/s6 for a medium drive fit. the tolerance for IT7 is 0.035 mm and that for IT6 is 0.022mm. the deviation letter of s suggests a 0.071 fundamental deviation. design the maximum acceptable shaft dismeter

Answer 1

90 H7/S6 Basic size 90mm Hole tolerance, 177 = 0.035 mm Shaft tolerance = 0.022mm, FD = 0.071 Acceptable shaft size = 90 + 0.022 + 0.071 Acceprable shaft size = 90.093 mm
