【摘要】 齿轮泵因具有结构简单、成本低、在高粘度下的抽吸性能好等优点 ,所以在轻化工行业高粘度液体的定量输送方面得到了广泛的应用。但是传统的二齿轮式齿轮泵存在较大的不平衡径向力 ,成为制约齿轮泵寿命的主要因素。本文应用行星齿轮传动原理构思出了新型齿轮泵的几种结构 ,提出了按“单位排量时泵的体积最小”作为优化目标的观点 ,并运用 MATL AB优化工具箱对泵的设计参数进行了优化分析 ,可为研究开发适合我国轻化工业生产条件的高粘度齿轮泵提供参考更多还原

【Abstract】 The gear pump, having advantages of simple and cheap configuration, insensible to dirty in the liquids, good sucking ability for heavy liquids, is widely used in transporting high-viscosity liquids in light and chemical industry. However, the heavier unbalanced radial force existed in the traditional two-gear’s gear pump is a chief factor to affect the pump’s service life. New types of gear pump based on planetary mechanism areworked out in this paper, a concept of "minimizing the pump volume per unit displacement" as the optimization function is suggested, and analysed by the optimization toolbox in MATLAB, which is for reference to develop the gear pump suitable for high-viscosity liquids in light and chemical industry.更多还原
