Abstract. Assembling of small-gear cylindrical gears is considered from the point of view of the require-ment to minimize the kinematic error in accordance with State Standards 9178-81 and 1643-81. A meth-od is proposed for calculating and minimizing the kinematic error of gears consisting of wheels with po-sition errors equal to the maximum permissible values specified by the GOST. Estimates of the kinemat-ic error are presented, recommendations for choosing the relative position of the gears in the process of gear assembly are formulated. The cases of assembly with multiple and non-multiple gear ratios are considered separately.
Keywords: kinematic error, GOST 9178-81, GOST 1643-81, exhibition effect, minimization, initial phases of harmonic components, degree of accuracy
