歯車潤滑の基礎研究 : 第6報, 歯車潤滑における不連続現象の基礎的解析

One of the most characteristic properties in the gear lubrication is the variation of lubricating condition on the gear-tooth surface with movement of mating point. In order to investigate the transitional behaviour of lubricating oil-film caused by the variation of lubricating condition, discontinuous phenomena in the gear lubrication are theoretically and experimentally analyzed. The hydro-dynamic squeeze-effect of lubricating oil-film is theoretically analyzed, and the variations of the pressure distribution, the minimum thickness and the load carrying capacity of lubricating oil-film are derived. With the roller testing apparatus, which gives discontinuous contact and load with rotation of test-rollers, the variation of oil-film thickness caused by the variation of lubricating condition is measured. These results give some good suggestions to the analysis on the transitional phenomena of lubricating oil-film on the gear-tooth surface.
