The invention belongs to the technical field of aviation electric actuators, and particularly relates to an angle-adjustable angular displacement actuator, the output of a direct current motor is finally converted into the rotation of an output shaft through straight tooth speed reduction, a screw rod pair, a gear and a rack, a screw rod nut of the screw rod pair is fixedly connected with the rack, and the rack is matched with the gear of the output shaft, and the adjusting device is used for adjusting the deflection angle of the output shaft and outputting a limiting protection function. The actuator is compact in structure, small in size, light in weight, large in output torque, high in bending moment resistance and capable of overcoming the defects of transmission of a multi-stage straight tooth harmonic reducer.

    本发明属于航空电动作动器技术领域,具体涉及一种角度可调节的角位移作动器,本发明将直流电机的输出经直齿减速、丝杆副和齿轮齿条最终转换为输出轴的旋转,所述丝杆副的丝杆螺母与齿条固连,所述齿条与输出轴的齿轮配合,所述调节装置用于调节输出轴的偏转角度及输出限位保护的功能。本发明结构紧凑、体积小、重量轻、输出力矩大、抗弯矩能力强,可弥补多级直齿和谐波减速器传动的不足。
