STRENGTH OF CYLINDER JOINT ADHESIVELY BONDED BY COUPLING

A method of joining two metal cylindrical shafts with adhesive couplin g is proposed. Two cylindrical shafts with the same diameter are conne cted by bonding through a cylindrical coupling with epoxy resin. The s trength of the shaft joint under tensile loading and torsional loading is investigated analytically and experimentally. The stress and strai n distributions of the shaft joint is analyzed by the finite element m ethod. The analyzed strain distributions in the joint are compared wit h experimental values. The joint strength is predicted by applying the strength laws of shafts, coupling, adhesive layer and adhesive interf ace between shaft and adhesive coupling. The effects of the coupling d imension on the joint strength are examined. It is shown that the adhe sive shaft joint can transfer the load by which the cylindrical shafts are plastically deformed.
