Embodiment Construction

[0010] The following describes the present invention in detail with reference to the drawings and embodiments:

[0011] Such as figure 1 with figure 2 As shown, a linear electromechanical static pressure servo mechanism includes a servo electric pump, a booster oil tank 6 and a hydraulic actuator 2. The servo electric pump includes an AC permanent magnet synchronous motor 1 and a bidirectional rotating constant piston pump 3. The AC permanent magnet synchronous motor 1 and the bidirectional rotating constant plunger pump 3 share the same drive shaft 5. The AC permanent magnet synchronous motor transmits the torque to the bidirectional rotating constant plunger pump 3 through the drive shaft 5, and controls the AC magnetic synchronization The rotation speed of the motor 1 controls the rotation speed of the bidirectional rotation constant piston pump 3, and the direction of the output high and low pressure oil of the bidirectional rotation constant piston pump 3 is controlled by c...

Abstract

The invention belongs to a mechanism used for controlling a servo system through a missile thrust vector so as to provide thrust for an electromechanical static pressure servo system on a missile, and specifically relates to a linear electromechanical static pressure servo mechanism. The linear electromechanical static pressure servo mechanism comprises a servo electric pump, a supercharging oil tank and a hydraulic actuator, wherein the servo electric pump comprises an alternating current permanent magnet synchronous motor and a bidirectional rotating constant plunger pump, the alternating current permanent magnet synchronous motor and the bidirectional rotating constant plunger pump share one drive shaft, and the torque is transmitted to the bidirectional rotating constant plunger pump by the alternating current permanent magnet synchronous motor through the drive shaft. The linear electromechanical static pressure servo mechanism has the advantages that the alternating current permanent magnet synchronous motor and the bidirectional rotating constant plunger pump are coaxially connected, so that the servo mechanism has the characteristics of compact structure, small moment of inertia and high dynamic response, the total weight of the electromechanical static pressure servo mechanism is reduced, and the servo mechanism adapts to rigorous weight requirements.

Description

Technical field [0001] The invention belongs to a mechanism used for a missile thrust vector control servo system to realize the thrust provided by the electromechanical static pressure servo system on the missile, and specifically relates to a linear electromechanical static pressure servo mechanism. Background technique [0002] The servo system of the strategic gliding missile has a long working time, the load average power of the servo system is large, the working condition of the servo system changes greatly, the installation space of the servo system is narrow, the weight is demanding, and the temperature is wide. This requires the electromechanical static pressure servo mechanism to have the characteristics of long-term, large capacity and high specific power at the same time, that is, long-term light and miniaturization requirements. At present, the "servo electric pump, booster oil tank and hydraulic actuator" adopts an up-and-down stacking layout that cannot meet the ab...
