Analysis and Design of Interference Fit Connection Assembly for Engineering Applications

Abstract

Abstract. This work focuses on practical solution to designing interference fit joint. For this, based on a series of analytical expressions, we studied structural effects on performances of shaft-hub interference fit assembly when the interference range remains unchanged. The results suggest that the contact stress gets lower with thinner hub and increasing fit diameter. Furthermore, the hub thickness has little effect on the strength of hub. Thicker hub shows larger contact stiffness while enhancing fit diameter can reduce contact stiffness. Too large radius of rounded edge has little effect on stress concentration of the assembly. The study provides a rapid and effective method of interference connection design for engineering.

Elastic-Plastic Stresses in Shrink Fit with A Solid Shaft

“…Most of the literature is interested in the stresses in the plastic domain of another geometries, for instance, Burenin et al [3] presented a problem of a shrink fit of a clutch on a shaft, that takes into account the dependence of the yield material strength on the temperature. An interference fit assembly of a solid shaft and a hub was modelled when interference range remains constant in the work of Shun Wang et al [4], to investigate how the structure of the assembly influences its contact stress, contact stiffness, and stress concentration. The last research viewed is the recently published work of Laghzale and Bouzid [5].…”
