| Abstract: | The straight conjugate internal gear pairs were studied, their meshing characteristics were analyzed and an integrated design method of their rotors was obtained. The selection and calculation of basic parameters were introduced, and the basic parameters and formulas were analyzed. The flow calculation equations were derived by integrating the gear pump design method with the working principle. The tooth profile equations were obtained according to the Willis theorem and the basic method of tooth profile design. Using an actual design example, the basic parameters and tooth profile equations were obtained, the rotor graphs were plotted, and the rationality and the validity of equations were verified. |
