数控交流永磁伺服变速变量斜盘式轴向柱塞液压电机泵
摘要：
一种数控交流永磁伺服变速变量斜盘式轴向柱塞液压电机泵，是由吸油口端盖、排油口端盖分别安装在定子两端，吸油口端盖、排油口端盖和定子上均有流道形成通路，转子安装在定子内，转子由转子铁芯、永磁体、泵套、缸体、右轴键套和左轴键套组成，转子铁芯上嵌有四块永磁体，泵套套装在转子铁芯的内部，并由吸油口端盖、排油口端盖上的轴承支撑，右轴键套安装在泵套的内部，左轴键套安装在缸体的外部，左轴键套上的矩形齿与右轴键套上的矩形齿相啮合；缸体与左轴键套安装在一起；缸体有七个柱塞与回程盘上的滑靴铰接，滑靴放入回程盘上的7个孔中，并通过内套、钢球、回程盘和回程弹簧将滑靴紧紧压在斜盘上，斜盘安装在吸油口端盖上；转速输出轴一端由排油口端盖上的轴承支撑，另一端插入缸体内部的花型槽中与缸体中心相连接，转速输出轴上设有内孔，其内安装套杯，套杯内安装可移动的内套，内套通过钢球和回程盘接触，在套杯和内套之间安装回程弹簧，钢球顶住回程盘将滑靴压到斜盘上；配流盘安装在排油口端盖上。
摘要（英）：

Provided is a numerical control alternating current permanent magnet servo variable speed variable quantity awry plate type axial plunger hydraulic motor pump, which includes an oil suction port end cover, an oil drain port end cover, a stator, a rotor, a rotating speed output shaft, a backflow disk and a tilting tray, wherein the oil suction port end cover and the oil drain port end cover are respectively installed at two ends of the stator, runners are respectively arranged on the oil suction port end cover, the oil drain port end cover and the stator to form passages, the rotor is installed in the stator, and the rotor is composed of a rotor core, permanent magnets, a pump sleeve, a cylinder, a right shaft key sleeve and a left shaft key sleeve. One end of the rotating speed output shaft is supported by a bearing on the oil drain port end cover, the other end is inserted into a pattern groove in a cylinder and connected to the center of the cylinder. The tilting tray is installed and fixed on the oil suction port end cover; and a thrust plate is installed on the oil drain port end cover. Through tightness fusion of the rotor part of the alternating current permanent magnet servo motor and the cylinder structure of the axial plunger pump, the numerical control of the motor pump can be realized and the numerical control alternating current permanent magnet servo variable speed variable quantity awry plate type axial plunger hydraulic motor pump can be widely applied to the civil and military industry fields.
