In this study, the reverse engineering method of planetary-gear reducer for track vehicles is investigated. A important factor in this study (Reverse engineering method of a planetary-gear reducer) is shift-coefficient and backlash. Therefore, a backlash was defined by gear class 4 of the KS(Korean Industrial Standard) and tolerance of base tangent length was defined by backlash. Center-distance of sun-gear, planet-gear, planet-gear and ring-gear is used to get sum of the shift-coefficient. The sum of the shift-coefficient is divided into gears properly. Shift-coefficient and backlash is applied to planetary-gear reducer degisn. A calculated gears tooth is checked by application program for a planetary gear.
