CALCOLO NUMERICO E SPERIMENTALE DEI MOMENTI DI SBLOCCAGGIO IN ACCOPPIAMENTI CONICI MISTI PER INTERFERENZA ED INCOLLAGGIO

Object of this work is to continue a research started last year and concerning the evaluation of the releasing moments in conic couplings realized with the simultaneous presence of interference and anaerobic adhesive. All the test specimens and the equipment tools were designed and realized in the laboratory of the DIEM. This equipment allows both the careful definition of the friction coefficient between the surfaces and the effect produced by the addition of anaerobic glue on the realising moment of the joint. First of all some insertion and releasing tests were performed with the purpose to define exactly the value of the first friction coefficient between the male and the female of the joint. Then a set of releasing tests has been performed over some mixed compression and adhesive coupling (glued with the anaerobic LOCTITE 638 adhesive) in order to evaluate the
