Problems solved by technology
The third stage of my country's Long March 6 rocket, which flew for the first time in September 2015, uses electromechanical servo mechanisms, but the thrust of the engine is small, and the power of the servo mechanisms is low, only tens of watts, which is relatively easy to implement in design
The American Centaur Liquid Hydrogen Liquid Oxygen upper stage single-engine configuration adopts electromechanical servo mechanism, but there is no level test and use report

Embodiment
[0058] This example gives a series of self-locking electromechanical servo mechanisms, such as figure 1 As shown, the servo motor 4 receives the drive signal, the output variable direction, the rotational movement of the transmission speed, the rotational movement, the lead screw 21 and the screw nut 22 convert the rotational motion into a straight movement, and passed through the wire bar 23 Out; the electromagnetic lock 31 locks the transmission shaft 331 in the power-off state to realize the lock of the servo mechanism output position;
[0059] like figure 2 As shown in series, the front-locking electromechanical servo mechanism, the front branch 1 is connected to the actuator assembly 2, and the actuator assembly 2, the actuator assembly 2, the self-locking module 3, the servo motor 4, and the rear branch The ear 5 is connected in series by screws; by adjusting the screw length of the thread between the front raging 1 and the actuator assembly 2, the overall mounting length of...

A tandem self-locking electromechanical servo mechanism adopts a tandem layout, from front to back, coaxially arranged front lugs, actuator assemblies, self-locking modules, servo motors and rear lugs; front lugs and actuation lugs The actuator assembly is connected through the thread set on the front lug, and the actuator assembly, self-locking module, servo motor and rear lug are connected in series coaxially through the screw; the servo motor receives the driving signal and outputs the rotating motion of changing direction and speed. , the actuator assembly converts the rotary motion into linear motion, and measures the displacement parameters, and the self-locking module locks the motor shaft of the servo motor in the power-off state to realize the locking of the output position of the servo mechanism.
Description
Technical field [0001] The present invention relates to a series type self-locking electromechanical servo mechanism for carrying rocket hydrogen liquid oxygen engine thrust vector control. Background technique [0002] The servo is an important equipment or system that carries a rocket for realizing thrust vector control of each sub. The main carrier rockets at home and abroad are used in electro-hydraulic servo mechanisms with servo valves as the core. my country's current main rocket is the third series, two, two and three sub-seizures, which use electro-hydraulic servo institutions, including hydraulic locking mechanisms, implementation, second-level flight segments and three-stage glid sections Engine lock function. With the increase in high-density emission demand in commercial space market and the intensification of market competition, the new launch vehicle focuses on rapid testing and mass production capacity. At present, my country's new generation of medium launch rock...
