Abstract
The authors of the article developed polymer composites based on aromatic polyamides, fluoropolymers, and phenolic resins, which have higher physical and mechanical properties than such construction materials as bronze and babbitt. These details, also have similar properties to carbon steels, and in terms of tribological properties, they are significantly superior to them. Polymer composite materials (PCM) were obtained by standard technology, as well as by combining (in situ) the initial components of polymer compositions. The effectiveness of the use of parts from the developed PCM in friction and sealing units of machines and mechanisms of the chemical and agricultural industry has been confirmed. These are the details: sealing of the cantilever shaft of the anchor stirrer; sliding bearings of the soil copying mechanism of the John Deere 1780 seeding machines and the damping mechanism of the cultivator's arrow paw; guide bushings of the movable traverse of the hydraulic press for polymer processing; overlays on the sliding guides of the moving table of the grinding machine (OШ 143).
