Existence of a Tunnelling Component of Electrical Drift Current through a DielectricFilm in High Frequency Knots with a Liquid and BoundaryFriction

Abstract

In particular functioning of high-speed rolling bearings with use of lubricant with rather big viscosity can happen without destructions of a high-resistance lubricant film. At the same time the annex of tribovoltage to rolling bearings leads to emergence of electric current caused in particular by tunneling effect of a charge across a film. Control of technical condition of frictional units has to be exercised according to electric parameters of the lubricant film which is implemented in friction zones. Values of these parameters depend on a condition of a lubricant film, and in particular on her temperature which is caused by degree of wear of details of frictional units which function under the influence of mechanical tension. The model can be used for technical diagnostics, and also for decrease of speed of process of wear. In practice the developed model can be used for those productions, vehicles, control systems where failure of frictional pieces can lead to failure of an expensive production inventory, the emergency cessation of production of goods, accidents of means of transportation of goods and people, loss of management of technical systems and also control systems of human activity.
