The paper presents the results of tribotechnical tests of polyamide PA 6 with additives of molybdenum disulfide and graphite in comparison with nitrile butadiene rubber, BNC rubber. The influence of the surface roughness of a 40X steel counter-tile on the friction coefficients from pressure is considered and the jamming loads from the sliding speed are determined. The tests were carried out on a friction machine with a vertical axis of rotation of the spindle according to the “plane-ring” scheme when the friction pair was lubricated with MGE-10A hydraulic oil. The test loads and sliding speeds were changed stepwise. It has been found that with a decrease in the surface roughness of samples of polymer materials, the friction coefficients decrease. Samples with graphite additives had the best indicators for reducing the coefficient of friction from pressure, followed by samples with molybdenum disulfide and PA 6 without additives. The bully resistance of graphite samples is 2 times higher than that of BNC samples. The samples with molybdenum disulfide were slightly inferior to the samples with graphite, but were better than PA 6.
Key words: polyamide / coefficient of friction / jamming load
