中文摘要:为进一步提高差速泵性能,提出了一种变性高阶比傅里叶非圆齿轮驱动的六叶片差速泵。建立了变性高阶比傅里叶非圆齿轮传动模型和六叶片差速泵性能指标计算模型,编写差速泵性能分析软件。计算和分析不同阶数比和不同变性系数下的差速泵排量、流量和脉动率等性能,计算结果表明,高阶数比非圆齿轮副有利于提高六叶片差速泵综合性能,变性系数改变有利于降低单泵脉动率。经试验台测试,在相同泵尺寸及管路环境下,变性高阶比差速泵第一叶轮输入轴微应变均值下降35.2%,降低了差速泵流量脉动。而非圆齿轮的不根切最大模数增加27.7%,增强了承载能力。排量变化不大,降低了1.2%。该设计更有利于低脉动、大载荷工况。

Abstract:In order to improve the performance of differential pumps, a six blade differential pump driven by denatured higher order ratio Fourier non-circular gear pairs was proposed. The denatured Fourier non-circular gear transmission model and the performance calculation model of the six blade differential pump were established, and the differential pump performance analysis software was compiled. The differential pump displacement, flow rate and pulsation rate were calculated at different order ratios and different denaturalization coefficients. The results showed that high order ratio was beneficial to improving the performance of six blade differential pump, and the change of denaturation coefficient was beneficial to reducing the pulsation rate of single pump. The performance of the six blade differential pump proposed was better than that driven by the ordinary Fourier non circular gear pairs. In the same pump shell size and pipeline environment, the micro-strain of input shaft of the first impeller of single pump was reduced by 35.2%. It was indicated that the pulsation rate of differential pump would be decreased. The maximum modulus was increased by 27.7%, the displacement of the differential pump was reduced by 1.2%. The design was more conducive to low pulsation and large load conditions.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
