Abstract. The paper presents the model of friction machine and its approbation in the friction geometry of thrust cylinder rotating on its axis against the flat counterbody. The paper also presents the principles of the registration of the friction torque by using strain gauge and calculation of friction coefficient in the fric-tion geometry used in the machine. The operability and accuracy of friction coefficient measurements by using the instrument is illustrated by the friction experiments with the symmetric and asymmetric friction pairs of organic and inorganic materials (polymers, crystals, metals).
Keywords: friction machine, thrust cylinder, strain gauge, friction moment, friction coefficient, polymer, metal, crystal
