Fatigue testing of taper press fits bonded with anaerobic adhesives

摘要

This article compares the static strength and the fatigue strength (under repeated stress)of axially loaded taper press fits,either dry or bonded with an anaerobic adhesive.A general increase of both static and fatigue strength with the contact pressure is observed,the strength buildup being greater for the dry joints than for the bonded ones.No significant difference between the static and the fatigue strength is measured for the dry joints.For the bonded joints,the fatigue strength decay is nearly independent (in absolute terms)of the assembly contact pressure.
