A dual reverse propeller device (100) for a ship is provided with: an outer shaft (12) to which a front propeller (1) is attached; an inner shaft (14) to which the rear propeller (2) is attached; a dual reverse thrust bearing (40) that transmits the thrust of the front propeller to the inner shaft; and a dual counter gear device (20) that rotates the outer shaft and the inner shaft in opposite directions to each other. The dual counter gear device (20) has an inner shaft thrust bearing (50) that supports the thrust of the inner shaft and maintains the axial direction position thereof. A thrust clearance measurement device (60) is provided with: an inner shaft position sensor (62) that measures an inner shaft position (F1) during forward movement and an inner shaft position (R1) during backward movement in the axial direction of the inner shaft during operation of a ship; and a thrust clearance calculation device (66) that calculates a first thrust clearance (C1) of the inner shaft thrust bearing.
一种船用双重反转螺旋桨装置(100)具备:外轴(12),其安装有前螺旋桨(1);内轴(14),其安装有后螺旋桨(2);双重反转推力轴承(40),其将前螺旋桨的推力传递至内轴;以及双重反转齿轮装置(20),其使外轴和内轴彼此沿相反方向旋转。双重反转齿轮装置(20)具有支撑内轴的推力并保持其轴向方向位置的内轴推力轴承(50)。推力间隙测量装置(60)具有:内轴位置传感器(62),其在船舶的运行中,测量内轴的轴向方向的前进时内轴位置(F1)和后退时内轴位置(R1);和推力间隙运算装置(66),其算出内轴推力轴承的第一推力间隙(C1)。
