Abstract
The fatigue-resistant spindle end of the invention is an elongated body having an axis of rotation. The spindle end comprises a drive engaging portion at one end, a male tool engaging tang at the other end, and a torque transfer section disposed therebetween. The torque transfer section includes a cylindrical journal portion and a frustoconical transition portion. The transition portion retains the geometric characteristics of both the tang and the cylindrical journal portion and blends those geometric characteristics so as to eliminate sharp discontinuities which may function as stress concentrators. In one embodiment of the invention, a stop barrel is also included to prevent a socket or other tool from engaging the transition portion.
