Investigation of journal slide bearings under the angle of their functioning

Paper presents the structure and principle of operation of a stand for measurements of influence of the lubrication method and process on functioning of journal slide bearings in their various technical states. Measurements performed on the stand make it possible to take advantage of the new method of evaluating the influence of physical and chemical properties of lubricating oil on the coefficient of friction in the mixed friction conditions. On the basis of the presented investigation results pertaining to journal slide bearings loaded with a constant-direction force during fast increasing and decreasing of loads within an assumed time interval, the Author has come to a conclusion that relation between physical and chemical properties of lubricating substance and properties of bearing metal can be determined by means of the operation indicator.
