Abstract. A probabilistic approach is applied to determining the accuracy of a gear using the example of tangential composite deviation. Using this approach at the design stage of the mechanism increases the accuracy of predicting the gear quality characteristics. The definition of the tangential composite deviation according to GOST 1643-81 is described, and a formula for calculating the tangential composite deviation function is derived with the account for amplitudes and initial phases of its constituent terms. For probabilistic calculation of the tangential composite deviation, the method of statistical tests – the Monte Carlo method is used. The experiment results are compared with the calculation of the tangential composite Использование стандартов при оценках кинематической погрешности зубчатых передач 561 ИЗВ. ВУЗОВ.

Conclusions are drawn about inaccuracies in the notes in GOST 1643 and the possibilities of using the standard.
