Based on the analysis of the gear′s force,the finite element method was applied to calculate the tangency intensity of the straight conjugate internal gear pump′s gear,and the result was compared with that calculated from empirical fomulas.The comparison shows that the calculation results of the two methods agree well thus it proves the feasibility and superiority of finite element analysis in the design and material selection of the conjugate internal gear pump.
