摘　　要：卸荷槽的设计是外啮合齿轮泵设计中最重要的部分之一,卸荷槽设计是否合理直接关系到齿轮泵的工作性能和使用寿命。以CBG型齿轮泵为研究对象,运用CFD技术进行流场解析,仿真研究了卸荷槽结构参数和不可控因素对困油压力的影响。结果表明:齿轮泵困油区压力影响因素较多,需要结合卸荷槽结构参数和环境性能参数综合考虑,为卸荷槽的优化设计提供参考。Unloading groove design is one of the most important in the design of gear pump parts,and the design is reasonable or not directly related to the working performance and the service life of the gear pump.Based on the research of CBG type gear pump as an object,using CFD technology flow field analysis,the effects were researched of unloading groove structure parameters and the uncontrollable factors on trapped oil pressure.The results show that more different unloading groove structure parameters are gotten for the influence of trapped oil pressure,combined consideration is in need of the unloading groove structure parameters and environmental performance parameters,which provide theoretic basis for the optimization design of the structure of the unloading groove.
