Joining Characteristics of a Tapered Coupling Joint

Abstract

To clarify static and dynamic properties in the circumferential direction of a tapered coupling joint, the relationship between loading torque and relative angle of torsion between a taper shank and a taper socket is determined for Morse tapers #3, #4 and #5. Static properties such as torsional stiffness of a tapered coupling joint and maximum sustainable torque are strongly influenced by the contact state between the taper shank and the taper socket. Dynamic properties such as natural frequency and damping capacity are determined using an impulsive response test of the tapered coupling joint. These properties are also influenced by the contact state between the taper shank and the taper socket.
