Scufng load capacity Safety factor against scufng according to [ BLOK3 ]: Safety factor scuffing BSoil Bioil4:3 where: ilocal contact temperature according to Eq. (4. at point oil lubricating oil temperature before contact entry approximate scufng temperature according to Table 4.4 Safety factor against scufng by the integral temperature method is calculated according to Table 4.6 Local treatment of micro-pitting resistance is theoretically possible, and is also useful, due to the dependence of load capacity with speed conditions and local tooth ank contact pressure. At present, however, no studies backed by experimental testresults are available to verify local load capacity.
