摘要
外啮合齿轮泵是液压传动系统中的主要元件,广泛应用于航空航天、军工、特种机械等行业,在现代化生产建设中发挥着不可替代的作用。本课题以CB-32型外啮合齿轮泵为例,采用Pro/E与ANSYS软件相结合的方法,对其壳体、轴和啮合齿轮进行了有限元分析,得到应力和应变分布云图,找出应力和应变较大区域。仿真结果表明:轴的应力和应变较大区域在轴的两端,壳体的应力和应变较大区域在壳体的高压腔附近的两个螺纹孔处,啮合齿轮的应力和应变较大区域在相互啮合的一对轮齿的啮合侧的齿根处。依据应力应变云图改变壳体的尺寸,可以对其进行优化设计,进而达到降低齿轮泵的制造成本、节约材料、提高寿命的目的。
External gear pump is the main component of hydraulic transmission system,which is widely used in machinery industry and plays an irreplaceable role in modern production and construction.This paper takes cb-32 external gear pump as an example,uses Pro/E and ANSYS software to analyze the shell,shaft and meshing gear,obtains the stress and strain distribution nephogram,and finds out the larger area of stress and strain.The simulation results show that:the greater stress and strain area of the shaft is at both ends of the shaft,the greater stress and strain area of the shell is at the two threaded holes near the high pressure cavity of the shell,and the greater stress and strain area of the meshing gear is at the root of the meshing side of a pair of meshing teeth.According to the stress and strain nephogram,changing the size of the shell can optimize the design,so as to reduce the manufacturing cost,save materials and improve the service life of the gear pump.
