Abstract. Contact stresses in thin-layer metal-polymer sliding bearings are investigated experimentally. A method for evaluating stresses using capacitive sensors based on Dacron film with a double-sided metallized coating is proposed. Radial contact stresses and their distribution in thin-layer polyamide plain bearings with different mounting gaps and coating thicknesses are estimated. The experimental results shows that the maximum contact stresses depend to a large extent on the structural dimensions of the sliding bearings: the gap size and the coating thickness.
Keywords: contact voltage capacitive sensor, a metal substrate, a Dacron film, a thin layer of polyamide coating
