JOINING CHARACTERISTICS OF A TAPERED COUPLING JOINT

To clarify static and dynamic properties in the circumferential direct ion of a tapered coupling joint, the relationship between loading torq ue and relative angle of torsion between a taper shank and a taper soc ket is determined for Morse tapers # 3, # 4 and # 5. Static properties such as torsional stiffness of a tapered coupling joint and maximum s ustainable torque are strongly influenced by the contact state between the taper shank and the taper socket. Dynamic properties such as natu ral frequency and damping capacity are determined using an impulsive r esponse test of the tapered coupling joint. These properties are also influenced by the contact state between the taper shank and the taper socket.
