Several characterizations of shaft-hub interference fit and adhesively bonded joints (Hybrid Joints) can be found today in literature, both for static and fatigue applications.

Then clearance-fit joints (clearance 0.04-0.06mm) were studied to evaluate the static performances of the adhesive; the assembly operation was carried out manually with pin and collar at room temperature. Finally the pin and collar have been manually assembled after: (i) heating the collar to 200 (°C) degrees and (ii) cooling the pin to -20 (°C) degrees. These two different assembly operations were performed in order get useful information concerning the adhesive strength depending on different coupling technique.

Abstract

Several characterizations of shaft-hub interference fit and adhesively bonded joints (Hybrid Joints) can be found today in literature, both for static and fatigue applications. However, a lack of information is still present about the influence of the assembly technique on the structural response of the joined parts. This paper aims at providing relevant information and comparisons concerning the coupling static strength (push out force) by performing some tests on pin-and-collar specimens made of steel, in the presence of an anaerobic adhesive (Loctite 638). At first the well-known press-fit assembly technique was analysed both with and without the adhesive; the assembly operation was performed by means of a hydraulic press with pin and collar at room temperature. Then clearance-fit joints (clearance 0.04-0.06mm) were studied to evaluate the static performances of the adhesive; the assembly operation was carried out manually with pin and collar at room temperature. Finally the pin and collar have been manually assembled after: (i) heating the collar to 200 (°C) degrees and (ii) cooling the pin to -20 (°C) degrees. These two different assembly operations were performed in order get useful information concerning the adhesive strength depending on different coupling technique.
