... Abstract A heavy duty facing lathe failed when the tool post caught one of the jaws on the rotating chuck, causing the spline shaft that drives the main spindle to fracture. A detailed analysis of the fracture surfaces (including fractography, metallography, and analytical stress calculations...

... revealed finely spaced striations on the crack surfaces, supporting a diagnosis of fatigue cracking. Crack initiation in the pulverizer shafts started as a result of fretting fatigue. Greater attention to lubrication was suggested, combined with asking the manufacturer to consider nitriding the splined...

... Abstract This paper presents a failure analysis of a reverse shaft in the transmission system of an all-terrain vehicle (ATV). The reverse shaft with splines fractured into two pieces during operation. Visual examination of the fractured surface clearly showed cracks initiated from the roots of...

...-power microscope examination of the spline of the shaft showed evidence of fretting wear debris; similar wear was observed on the splines of the mating bevel gear. It was concluded that the splines had failed by severe fretting wear. Fretting damage was also observed on the shaft face adjacent to the...

... and applies to all three regions of crack growth. Industrial fan shafts are typically forged from medium-carbon steels. Primary fatigue stresses are generated from gravity bending and are fully reversed during each revolution at rates of 900 to 1800 revolutions per minute or 15 to 30 Hz. The...

... relatively deep and narrow. A thin, circular shaft in torsion may buckle into a helical configuration when a critical moment is exceeded. Creep or distortion from other causes may change the dimensions of a structure so that it becomes susceptible to buckling. Further details can be found in references such...
