Abstract: Based on the available theoretical and half-empirical methods of gerotor design, one opti-mization 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 respec-tively 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 out-let cavity and cavitation phenomenon has not been detected. The optimization satisfies the design re-quirements.
Keywords: inner engaging cycloidal gerotor; inlet and outlet cavities; optimization design; bench test
0引言
内啮合摆线转子泵因其结构紧凑、运转平稳、脉动小、不易产生“气穴”等优点而被广泛用作多种型式发动机的机油泵。其性能好坏直接影响润滑系统工作的优劣。一般内啮合摆线泵的外转子选用标准件，其设计的核心是进出油腔结
构设计。
目前国内针对内啮合摆线转子泵进出油腔的主要研究基于理论及半经验设计，如毛华勇等)建立了进出油腔面积计算式，并分析了实际设计时应考虑的转速、油液黏度和进油方式等影响因素索；屈盛官等[3]从理论上分析了影响转子机油泵容积效率的主要原因，并从选择合适的进油槽尺寸、合适
