Abstract. The methods for calculating the accuracy of the involute cylindrical gear train (the dead course of the transmission) are considered. Expressions from standards GOST 21098-82 and GOST 1643-81 are analyzed, formulas for calculating the dead run of the gear transmission by the maximum method (in which all parameters take the maximum values) are derived. A formula is given for transferring the magnitude of the dead travel of the transmission from micrometers to angular minutes. Calculation of the dead run of the gear transmission by a probabilistic method (the Monte Carlo method) is performed. An algorithm for calculating the dead path is presented.
