Investigation on Dynamic Oil-film-formation and Pitting in Spur Gear : 2nd Report. Quantitative Evaluation of the State of Local Oil-film-formation

抄録

For the sake of quantitative evaluation of the local state of oil-film-formation in spur gears, the authors tried to analyze statistically the voltage between meshing teeth which was measured by electrical resistance method, using an analog-digital converter and an electronic computer. The local state of oil-film-formation at every meshing position on the line of action or no a pair of gears was evaluated as the distribution of the voltages between meshing teeth. It is shown that the local state of oil-film-formation in gears is affected significantly by the dynamic load and the surface defect of gear teeth. These analyses will be useful for elucidation of the mechanism of pitting in gears.
