The present work aims at defining the anaerobic adhesive residual strength in press-fit and adhesively bonded cylindrical joints, loaded with a tension tension fatigue cycle. The final purpose is to evaluate the possibility to reduce the interference level by taking advantage of the adhesive strength. The tested specimens are some shaft hub cylindrical joints made of different materials in contact: the hubs are always made of steel alloy while the shafts are made both of steel alloy and of aluminium alloy. Firstly some coupling and decoupling tests have been performed to evaluate the static strength of the joints, calculated as the addition of the interference contribution and the adhesive contribution. Then the fatigue tests have been performed to evaluate the adhesive residual strength after 106 tension tension fatigue cycles. The fatigue cycles have been differentiated and related to the static strength of the joint.

Abstract
The present work aims at defining the anaerobic adhesive residual strength in press-fit and adhesively bonded cylindrical joints, loaded with a tension tension fatigue cycle. The final purpose is to evaluate the possibility to reduce the interference level by taking advantage of the adhesive strength. The tested specimens are some shaft hub cylindrical joints made of different materials in contact: the hubs are always made of steel alloy while the shafts are made both of steel alloy and of aluminium alloy. Firstly some coupling and decoupling tests have been performed to evaluate the static strength of the joints, calculated as the addition of the interference contribution and the adhesive contribution. Then the fatigue tests have been performed to evaluate the adhesive residual strength after 106 tension tension fatigue cycles. The fatigue cycles have been differentiated and related to the static strength of the joint.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
