WebAug 21, 2024 · In addition to the experimental data generated for PEEK, literature values of the flank load carrying capacity for oil-lubricated PA66 acc. to VDI 2736 are also plotted. The PA66 S‑N-curve is plotted for a safety factor of S H = 1.0 and a flank temperature of ϑ flank = 90 ℃. The PEEK and PA66 fatigue data have approximately the same gradient. Webfactor (function of the crowning and the deformation of the shafts) must obviously be recalculated. For the calculation of surface durabil-ity, two separate calculations are made, one for each flank, each for the number of hours actually occurring on that flank, as shown from the spectrum. The flank safety is the lowest of those calculated.
