水潤滑スラスト軸受材料の研究

In some special bearings, there is no utilizable lubricant without water which has the viscosity about one-hundredth of the oil. For the material of water lubricated bearing, it is necessary to find out such material that performs safely and displays a small frictional loss at the boundary lubricating condition. It is the principal object of the present investigation to find out the bearing material usable in the range of the normal to comparative high water temperature. The frictional characteristics, the wearing characteristics, the swelling quality and the thermal expansibility were investigated in the following driving conditions : water temperature rangs from 10 to 90°C, bearing pressure from 2 to 8 kg/cm².
