Abstract

The influence of tip interference on scoring load capacity was studied using gears having tooth profile wear due to scoring on the approach side. The results were compared with those obtained with gears having no profile wear from viewpoints of scoring load and scoring temperature, taking the lubrication state on the working flank into consideration. The tip interference on the approach side should be reduced because, unlike on the recess side, it diminishes the scoring load capacity. In the mixed lubrication state, the bulk temperature on the working flank is suitable for an index in calculating the scoring load capacity of a spur gear pair. The scoring temperature on the recess side can be estimated well by the bulk temperature on the outer surface of the cylinder just before seizure in two-cylinder tests, provided that the specific sliding and the sliding velocity at the end of gear meshing are taken into account.
