The invention provides a screw pitch feedback device for a ship lateral thruster, and relates to the technical field of thrusters, the screw pitch feedback device comprises a base, a transition sleeve is arranged in the middle of the bottom end of the base, and the transition sleeve is used for installing the base on a gear box body; a feedback shaft is rotatably installed in the middle of the inner side of the transition sleeve, the top of the feedback shaft is connected with an angle sensor, and the bottom of the feedback shaft is connected with a feedback rod. A mounting seat is arranged at the top of the base, the top of the feedback shaft penetrates through and extends out of the mounting seat, and the angle sensor is mounted in the middle of the inner side of the mounting seat; a dial is arranged at the top of the base and located at the bottom of the mounting base. According to the device, when the feedback shaft rotates, the angle sensor and the scale pointer can be synchronously driven to rotate, then a stroke mechanical signal and an electric signal are generated in real time, and therefore the output signal change of the feedback element is achieved; the accuracy of signal feedback is enhanced, and the situation of misoperation caused by failure of one feedback signal is effectively prevented.

    本申请提供了一种用于船舶侧向推进器的螺距反馈装置,涉及推进器技术领域,包括底座,底座的底端中部设置有过渡套,过渡套用于将底座安装在齿轮箱体上;过渡套的内侧中部转动安装有反馈轴,反馈轴的顶部连接有角度传感器,反馈轴的底部连接有反馈杆;底座的顶部设置有安装座,反馈轴的顶部穿过安装座且伸出,角度传感器安装在安装座的内侧中部;底座的顶部设置有刻度盘,刻度盘位于安装座的底部。本发明装置在反馈轴转动时,可同步带动角度传感器和刻度指针进行转动,进而实时产生行程机械信号及电气信号,从而实现反馈元件的输出信号变化;增强信号反馈的精准度,同时还有效防止一个反馈信号失效时造成操作失误的情况发生。
