In this paper, the formula for calculating centrifugal stress of spur gears is deduced. In order to calculate the centrifugal stress, a numerical table of the coefficient A is given. At the same time, the influence of the number of teeth Z on the value of the coefficient A is analyzed. The curve of the value of the coefficient A along with the number of teeth Z is plotted, which provides a theoretical basis for the calculation and design calculation of the gear strength.
