摘　　要：为了使定量泵输出多级定流量以及定量马达输出多级定转速和定转矩,在比例型和并联型齿轮多泵/多马达的基础上提出了齿轮型多泵多马达传动理论。基于1-1比例型和3并联型齿轮多泵/多马达设计了2种齿轮型多泵多马达传动系统,并阐述了其工作原理和特点,且对2种齿轮型多泵多马达传动系统在不同工作方式下的输出特性进行了理论分析和拓展,并搭建了齿轮型多泵多马达传动系统试验平台。试验结果表明:齿轮型多泵多马达传动系统在不同工作方式下可输出多级定转速和定转矩,且各级转速和转矩存在一定的比例关系。试验结果与理论分析基本一致,验证了理论分析的正确性,为齿轮型多泵多马达传动系统的设计与研究奠定了基础。In order to make constant displacement pump output of multi flows,and make constant displacement motor output of multi speeds and multi torques,the proportional type and parallel type of gear multi-pump（multi-motor） consisted of several single pumps and motors were designed,a theory of gear multi-pump and multi-motor driving system was presented based on the proportional type and parallel type of gear multi-pump（multi-motor）.The principle of two multi-pump（multi-motor） was introduced,two gear multi-pump and multi-motor driving systems were designed based on 1-1 proportional type and 3parallel type gear multi-pump（multi-motor）, and the principle and characteristics of them were introduced,the output characteristics of the two gear multi-pump and multi-motor driving systems in different working ways were analyzed,and the output characteristics of two gear multi-pump and multimotor driving systems consisted of X-Y proportional and Z parallel gear multi-pump（multi-motor） were expanded,the experimental platform of gear multi-pump and multi-motor driving system was built.The result showed that the driving system can output multi speeds and multi torques,and there was a certain ratio between the speed and torque levels.The experimental result was consistent with the theoretical analysis,which showed the correctness of theoretical analysis.The research provided a basis for design and research on multi-pump and multi-motor driving system.
