Abstract
The study of the properties of consistent and liquid oils is currently receiving much attention in tribology. This is because lubrication is one of the most effective ways to improve machine durability. At the same time are practically no mathematical descriptions of the mechanisms of grease lubrication, which is necessary for predicting and calculating the wear of machines. When studying the wear of surfaces under boundary lubrication conditions, it is necessary to know the stiffness characteristics of a thin layer of lubricant under normal and tangential stresses. In this paper, a method is proposed for determining the function of the contact tangential characteristics of a thin oil layer between solid deformable surfaces. A thin layer of grease is placed between two hard discs. By measuring the angle of rotation and the moment on the second disc, the dependence of the moment on the angle of rotation is determined. The contact mechanics of torsion of a thin circular lubricant layer has been developed and relations for determining the parameters of the shear diagram of a thin lubricant layer have been obtained. According to the developed method, the Fiol-3 grease was tested and the parameters of the shear diagram were determined.
