| description | Various types of tribotechnical polymeric materials are widely used for metal-polymer (MP) gears to ensure their reliable operation in dry sliding friction conditions. These include polyamides, polyacetals, polyetheretherketones, polyethylene terephthalate, and other polymers. The wear resistance of polyamides (PA6, PA66, PA6+30GF, PA6+30CF, PA6+MoS2, PA6+oil), polyacetals (POM-H, POM+35PTFE, POM+20PTFE, POM+60Bronze, POM+20PTFE+30Bronze; POM+10PTFE+20Bronze, POM+15PTFE+15GF, POM+10PTFE+10GF, POM+10PTFE+20Bronze+10GF, POM+10PTFE+15Bronze+5GF), polyetheretherketones (PEEK, PEEK+30GF), and polyethylene terephthalates (PET, PET+PTFE) on steel has been studied in this work. In order to determine their wear resistance and sliding friction coefficient, the authors’ method of model triboexperimental studies of materials under sliding friction according to the pin-on-disk scheme was used. As a result, their wear resistance indicators were established and used to determine the wear resistance characteristics by the least squares method. They are necessary for the mathematical modeling of the wear kinetics of MP gears using the corresponding author's method. In order to compare the wear resistance of the studied polymeric materials and their compositions over an extended range of specific friction forces, graphical indicators of wear resistance (wear resistance diagrams) were constructed. On the basis of these diagrams, quantitative and qualitative regularities of the tribological behavior of the studied polymers in a tribopair with steel 45 were established. The change in the friction coefficient with increasing contact pressure was also investigated. The qualitative and quantitative parameters of this effect were determined. |
