Abstract

The article deals with the tribological processes which accompany the changes in the solid and liquid phases of the polymer plate materials in order to reduce the energy loading of the metal and polymer pair sections of the drilling rig drawworks belt and drum brakes. Electrically and thermally stimulated depolarization and polarization processes in the surface coatings of the metal and polymer pair frictional elements that are installed into the drawworks brake drums were analyzed in detail in the article. The analysis of the processes that happen to the polymer material components when the electrical fields change and elements of the metal and polymer friction pair sections of the drawworks belt and drum brake interact was conducted. Reduction of the energy loading of the metal and polymer friction pairs of the developed belt and drum brake design at different modes of loading was achieved. It made it possible to utilize frictional brake plates at face temperatures that are lower than the acceptable ones for their materials. It allowed not only to reduce the friction force but also to stabilize the deterioration and friction characteristics of the friction nodes of the belt and drum brake. The interrelation of the polymerization processes of the metal and polymer friction pairs of the drilling rig drawworks belt and drum brakes with the field density that is generated on the microelevation spots of the friction pairs was studied.
