WebInterference fits are commonly used with aircraft fasteners to improve the fatigue life of a joint. Introducing interference between parts [ edit] These fits, though applicable to shaft and hole assembly, are more often used for bearing-housing or bearing-shaft assembly. Tightness of fit [ edit] WebThe interference therefore varies almost directly with diameter, and the difference between its minimum and maximum value is small to maintain the resulting pressures within reasonable limits. Note: There is no symbol in the standard for the shaft tolerance of FN1. Supplements: ANSI limits and fits calculator .
WebFor 1.0” diameter (nominal) shaft to fit into a hole, specify the shaft and hole tolerance for FN1 fit. Determine the amount of interference. If the OD of the outer member is 1.6”, determine the interfacial pressure and the stresses (use Lamé equation in the class notes) in the members if both members are steel.
