摘　　要：通过双定子液压马达结构分析,提出了双定子液压马达差动连接的方法。在此基础上,分析了不同作用数的双定子液压马达差动连接方式,推导出不同差动连接下液压马达输出转速和转矩的表达式;针对双定子液压马达排量比例系数C对其差动连接方式的影响,分别找出了单作用、双作用以及多作用双定子液压马达中会使液压马达差动连接出现重复或死点现象的C的取值,得到了重复组数和死点数,为液压马达差动连接的理论研究提供了一条新途径。From the perspective of differential cylinder, the differential connections of hydraulic motor were studied, and a differential connection method was put forward. Through the analysis of the differential connections of different-acting double-stator motors, the mathematical expressions of the motor＇ s rotational speed and torque were obtained. As for the effect of motor displacement scale factor C on the differential connection, the values of C for the single-acting, double-acting and multi-acting double-stator motor were found out respectively. These can make the motor differential connections turn out the same results or even fail to work. The number of repeated groups and failure points was calculated. This work will offer a new way for the theoretical research of hydraulic motor differential connection.
