Transferability of the scuffing load capacity of gear oils determined on spur gears to hypoid gears

Abstract The scuffing load carrying capacity is a decisive design criterion in the development of gears. In addition to gear geometry, entire tribological system gearbox must also be taken into account. Besides loads and speeds occuring during operation gears, lubricant used its additives have significant influence on capacity. particular, hypoid gears show an unfavorable combination high sliding velocities contact stresses tooth with regard failure mode scuffing. To ensure safe operation, highly additivated oils are generally transmissions. Since it not possible determine basis physical or chemical oil data alone, experimental test methods necessary. Due oils, limits many reached. order testing as close their application new was developed. However, since spur can carried out more quickly less resource effort, applicability S‑A10/16.6R/90 investigated. comparability two transferability determined evaluated scope this paper.
