Problems solved by technology
Among the existing 3D modeling software mentioned above, some commercial software lacks the basic standard gear generation module, although the remaining software has a gear modeling module, it can only generate standard gears, and the modified gear digital design module is even blank
In order to complete the modeling of the modified gear, the method of drawing lines one by one in the sketch environment and constraining the tooth profile of the modified gear can only be used, and the law of the modified curve function cannot be accurately controlled, and the modeling effect of the modified gear is very unsatisfactory. Many repetitive operations
Therefore, the existing 3D software is very limited and inefficient in dealing with modified gear modeling, which seriously affects the follow-up gear analysis and gear machining work

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 gear digital modeling method is much convenient to use.
