| 摘要:在应用现有摆线机油泵进出油腔设计理论与半经验方法基础上,对某型内啮合摆线机油泵的进出油腔提出了改进方案,通过台架试验对机油泵性能进行了试验研究。试验结果表明,进出油腔结构优化后,机油泵的容积效率与总效率分别提升3%和2.9%。应用Pumplinx软件对机油泵进行仿真分析。结果表明,仿真结果与试验数据基本吻合,进、出油腔压力分布均匀,无气蚀,机油泵的优化改进满足设计要求。 |

| Abstract:Based on the available theoretical and half-empirical methods of gerotor design, one optimization scheme of inlet and outlet cavities for a inner engaging cycloidal gerotor has been presented. Experimental investigation has been carried out through bench test, and the results show that 3% and 2.9% increase of the volume efficiency and total efficiency of the gerotor has been achieved respectively through the optimization of inlet and outlet cavities. Then, the numerical investigation of the gerotor has been carried out with the commercial software Pumplinx. The simulation results show a good agreement with the experimental data. The pressure is uniform in most area of the inlet and outlet cavity and cavitation phenomenon has not been detected. The optimization satisfies the design requirements. |
