The invention discloses an electrically-driven marine pitch-adjustable propeller propelling device. The electrically-driven marine pitch-adjustable propeller propelling device comprises two pitch-variable mechanisms, a rear hub body, blades, a front hub body, a propeller shaft flange, a transmission shaft and a guide piston, one side surface of the rear hub body is connected with one side of the front hub body, two variable-pitch mechanisms are symmetrically arranged in a cavity formed between the rear hub body and the front hub body, the two variable-pitch mechanisms are connected through a mounting plate, paddles are mounted on the side wall of the joint of the rear hub body and the front hub body, and the other side of the front hub body is connected with one side of the transmission shaft group; a servo motor is installed in an inner cavity of the transmission shaft, and an output shaft of the servo motor is connected with one end of a transmission trapezoid lead screw. According to the design, the electric cylinder is adopted for driving the variable pitch, accurate control and quick response of the pitch can be achieved, and meanwhile when a fault occurs, for example, the variable pitch thrust exceeds a preset set value, overload protection can be achieved, and an alarm signal can be output.

    一种电动驱动的船用调距型螺旋桨推进装置,所述电动驱动的船用调距型螺旋桨推进装置包括两个变距机构、后毂体、桨叶、前毂体、桨轴法兰、传动轴与导向活塞;所述后毂体的一侧面与前毂体的一侧连接,后毂体与前毂体之间形成的空腔内对称设置有两个变距机构,两个变距机构之间通过安装板连接,后毂体与前毂体连接处的侧围上安装有桨叶,前毂体的另一侧与传动轴组的一侧连接;所述传动轴的内腔安装有伺服电机,伺服电机的输出轴与传动梯形丝杆的一端连接。本设计采用电动缸驱动变距能够实现螺距精确控制和快速响应,同时当出现故障时,如变距推力超过预计设定值,还可以实现过载保护并输出报警信号。
