The use of composition material based on the polyamide (caprolon) Ertalon 4.6 as an anti-friction material in the sliding units in the aviation industry is considered. Low carbon electrotechnical sheet steel 21864 of different concentrations was used as filler of composite material. The article presents the thermal calculation of plain bearings with polymer insert in different operating modes. It is determined that the addition of a metal filler to polyamide causes a temperature decrease in the friction zone due to the effective heat exchange from the shaft to the bearing housing. The article conducts a study of tribo-technical properties of the proposed composite material on installation PT-4C under sliding conditions according to the scheme “cylinder-plane”, as well as modeling of the support unit in the software complex DS SolidWorks. It has been experimentally determined that the addition of finely dispersed steel filler enhances the antifriction properties of the Ertalon 4.6 polymer and extends the temperature range of the composite insert performance. Increasing the filler concentration to 20% results in a reduction of the friction coefficient by an average of 3.6 times and an increase in the temperature range of composite material use to 100 °C. The load-bearing capacity of the composite material bushing is increased to 25 MPa at a 20% filler concentration respectively.
The practical significance of the work lies in the analysis of the antifriction properties of the polymer with metallic filler in comparison with the polymer without filler, which will prove the effectiveness of the use of such polymers in friction units instead of non-ferrous metals (bronze, babbitt). |
