This paper aims the development of the calculation technique of gear wheels tooth pair stiffness in one-pair gearing by the finite elements method and its application for an estimation of tumbling mills open tooth gearings stiffness. The calculation of stress state was carried out by the finite elements method. At the first stage the analytical model of a gearing was formed. Based on the key geometrical parameters and drawings the three-dimensional geometrical model of the tooth gearing was designed. The physical properties of the constructional materials were set. The geometrical model split into finite elements. The current situation in the field of the tooth gearings stiffness calculation was investigated. The special attention was paid to shortcomings of the existing standards with reference to the large-sized tooth gearings. The authors sowed the advantages of the finite elements method use for calculation of the tooth gearing elements strain state. The algorithm and a calculation technique of the tooth gearings stiffness by means of the finite elements method was presented.
