“…Pitting/spalling type behaviour was observed after approximately 500,000 cycles, consistent across five repeats. A similar investigation into the raceway fatigue failure mechanism has recently been carried out by Song et al, 17 following on from the development of a rig to investigate tripod type CVJs. A test rig is developed which represents a reduced ball type joint, with the number of balls reduced from six to four, and the outer raceway fixed onto the test rig.…”

Constant Velocity Joint (CVJ) mechanisms enable torque transmission between two shafts at a fixed or variable angle. Cross groove CVJs are typically used in high performance automotive applications due to their versatility and light weight. Critical failure modes, such as pitting or abrasive wear, occur due to the harsh tribological conditions at ball reversals. In this research, an existing mathematical model is developed further for the case of cross groove CVJs including an accurate contact mechanics model. The developed model is validated against a published data set from literature. Surface topography of worn raceways are experimentally measured and the results from the developed model are corroborated with the measured surface parameters. This improved model shows the correlations between predicted contact force variation and wear scar depths during ball reversals, hitherto not reported in the literature.

“…A detailed tribological model would provide a more informed understanding of the contact friction and its effects. For investigation of fatigue failure modes observed in the substrate material 3,16,17 it would be essential to determine the subsurface stress distribution as a result of the normal and shear (traction) forces in the contacts.…”
