摘　　要：针对一款变速箱的双联内啮合齿轮泵在实际运行过程中存在的泵容积效率低的问题,该文从泵的结构上进行了原因分析,在此基础上,通过增加后端盖、紧固螺钉等措施对泵进行了结构优化设计,同时对优化前、后的双联内啮合齿轮泵进行了试验对比测试,测试结果表明,优化后的双联内啮合齿轮泵的容积效率明显高于优化前的,说明此次结构优化设计改进能够减小泵的泄露,提高泵的容积效率,保证其工作的良好性能。In response to the problem of low pump volume efficiency in the actual operation of the dual internal meshing gear pump for a gearbox,the cause analysis is conducted on the pump structure.Based on this,the pump structure is optimized by adding rear end covers,fastening screws,and other measures;at the same time,comparative tests are conducted on the dual internal meshing gear pump before and after optimization.The test results show that the volumetric efficiency of the optimized dual internal meshing gear pump is significantly higher than that before optimization,indicating that the structural optimization design improvement can reduce pump leakage,thereby improving the volumetric efficiency of the pump and ensuring its good performance.
