For K H V involute planetary gear reducer with small tooth number difference,the optimum design mathematical model is set up,the software system for auto design and drawing of reducer with small tooth number difference is developed.In order to enhance pass rate of products,binding conditions under such circumstances that internal gear is machining by new and old cutters are considered synthetically.In addition,CAD is utilized during verifying intensity and life span of main transmitted components of reducer with small tooth number difference.By testing weak parts some parameters are adjusted,in order to fast and accurately determine specification and version of standardized components, and main size of other transmitted components. This paper set up the database of series plans of reducer with small tooth number difference.By analyzing correlative theory and calculating,the simulation software of internal gear pair meshing is developed.
