Shape-correction gear digital modeling method based on power function

The invention relates to a shape-correction gear digital modeling method based on a power function. The shape-correction gear digital modeling method includes the following steps that proper shape-correction gear design parameters and shape-correction parameters are selected according to working conditions; a shape-correction curve power function rule is selected, and relevant unknown coefficients in the shape-correction curve power function rule are derived; based on a secondary development platform of three-dimensional modeling software, an input interface is set up, the shape-correction gear design parameters and the shape-correction parameters are input, and digital modeling of a three-dimensional shape-correction gear is finished. According to the shape-correction gear digital modeling method based on the power function, a digital model of the shape-correction gear can be fast generated as long as the gear design parameters and the shape-correction parameters are input by a user, and the shape-correction
