Fig. 34 Wear of universal-joint slip spline shaft of 1141 steel. Wear was measured as backlash on a 300 mm (12 in.) radius under a torque load of 9.5 N · m (7 lb · ft). Sleeve yokes of 1140 steel were quenched and tempered to a hardness of 241 to 285 HB. Shafts were heat treated to 228 or 340 More

Fig. 375 Reversed torsional fatigue fracture of splined shaft due to overtempering. The SAE 4150 part was oil quenched and tempered to 34 HRC throughout—a hardness too soft for the application. Note the “starry” pattern characteristic of multiple fatigue cracks. 3.5× (D. Roche and H.H More

Fig. 515 Surface of torsional-fatigue fracture in a splined shaft of AISI 8620 steel that was carburized and case hardened. Multiple fatigue cracks evidently formed at the roots of the splines and then joined to penetrate much of the case before final fast fracture occurred. 2× More

Fig. 528 Longitudinal section through a spline of the shaft in Fig. 525 , showing inclusions, banding, and some free ferrite. The cause of the fracture was improper design; corners at bases of splines had adequate radii for most of the spline length, but these radii were reduced, forming More
