The invention relates to a swing type electric steering engine, and belongs to the technical field of ship design and manufacturing. The electric steering engine is arranged in a box body and comprises a servo motor, a driving gear, a driven gear, a lead screw pair, a rack and a rocker arm gear; a driving gear is arranged on the servo motor, and the driving gear is in meshed connection with a driven gear; a lead screw shaft of a lead screw pair is arranged on the axis of the driven gear in a penetrating mode, a rack moving along a straight line is arranged on a nut of the lead screw pair, and the rack is connected with the tooth face of the rocker arm gear in a meshed mode. The rocker arm gear further comprises an output shaft, and the axial direction of the output shaft is perpendicular to the length direction of a lead screw shaft of the lead screw pair. Through the design that the steering engine installation space and the working space coincide, the problem that an existing electric steering engine needs a large space during installation and use is solved, and the steering engine is simple in structure. The electric steering engine provided by the invention is suitable for back-and-forth swing output under the condition of a narrow installation working space, and the operation field of equipment is expanded.

    本发明涉及一种摆动式电动舵机,属于船舶设计制造技术领域。电动舵机设于一箱体中,包括伺服电机、主动齿轮、从动齿轮、丝杠副、齿条和摇臂齿轮;伺服电机上设有一主动齿轮,主动齿轮与一从动齿轮啮合连接;从动齿轮的轴心上穿设有一丝杠副的丝杠轴,丝杠副的螺母上设有沿直线移动的齿条,齿条与摇臂齿轮的齿面啮合连接;摇臂齿轮还包括输出轴,输出轴的轴向与丝杠副的丝杠轴的长度方向垂直。本发明通过将舵机安装空间和工作空间重合的设计,解决了现有电动舵机在安装使用时需要较大空间的问题,且舵机结构简单。本发明提供的电动舵机适用于狭小安装工作空间条件下的往返摆动输出,扩展了设备的作业领域。
