【 摘 要 】

We propose a technique for calculating the dynamics of the temperature field in a system of polymeric sliding bearings, taking into account the speed of rotating shaft. A numerical algorithm for calculating the thermal processes in sliding bearings on a common shaft is developed by solving a system of two-dimensional and three-dimensional heat equations. We determined the time step, depending on the speed of rotation of the shaft by computational experiments. This allows us to determine the temperature fields with acceptable accuracy for practical use. The test results of sliding bearings made of composite material based on fluoropolymer are presented, which show the adequacy of the proposed mathematical model to the real thermal process.
