摘要  针对采用传统经验公式分析计算齿轮泵齿轮接触强度存在计算过程相当复杂、繁琐,误差较大的问题.在分析齿轮受力情况基础上,采用有限元法对直线共轭内啮合齿轮泵齿轮接触强度进行计算,并与经验公式计算的接触强度进行比较分析.结果表明,两种方法计算结果基本吻合,证实了采用有限元法分析计算的可行性与优越性,为直线共轭内啮合齿轮泵齿轮的设计、选材提供了一种新的方法,具有一定的工程应用价值.

Abstract:  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.
Key wordsstraight conjugate internal gear pump   contact intensity   free meshing   finite element analysis   penalty functional method
