The invention discloses an improved structure of stern shaft tube. The improved structure comprises a stern tube, a front bearing, a rear bearing, a plugging device, a temperature measuring device anda positioning device; the plugging device comprises a front shaft sleeve fixedly connected to one end of the stern tube, the other end of the stern tube is fixedly connected with a rear shaft sleeve,one end of the rear shaft sleeve is fixedly connected with a propeller hub, and the interior of the rear shaft sleeve is fixedly connected with a sealing block; the temperature measuring device comprises a sealing device fixedly connected to one end of the rear shaft sleeve, the sealing device comprises a fixing sleeve fixedly connected to one end of the front shaft sleeve, a sleeve is fixedly connected into the fixing sleeve, and a wire sleeve is sleeved with the sleeve; the positioning device comprises a limiting ring fixedly connected into the sealing block, and the limiting ring is connected to the outer side of the shaft rod in a sleeving mode. One side of the limiting ring abuts against one side of the rear bearing. When the temperature sensor is damaged, the temperature sensor andthe probe are pulled out of the connecting groove and the sleeve under the action of the wire sleeve, so that the temperature sensor is convenient to replace, and the damaged temperature sensor can bereplaced without docking a ship, and thus the ship is convenient to use.

    本发明公开了艉轴管改进结构,包括艉管、前轴承和后轴承以及封堵装置、测温装置和定位装置,封堵装置包括固定连接在艉管一端的前轴套,艉管的另一端固定连接后轴套,后轴套的一端固定连接桨毂,后轴套的内部固定连接密封块,测温装置包括固定连接在后轴套一端的密封装置,密封装置包括固定连接在前轴套一端的固定套,固定套的内部固定连接套管,套管的内部套接有线套,定位装置包括固定连接在密封块内部的限位环,限位环套接在轴杆的外侧,限位环的一侧抵紧后轴承的一侧。当温度传感器损坏后,将温度传感器和探头在线套作用下从连接槽和套管内部抽出,从而使更换温度传感器方便,船舶不需要进坞就能更换损坏的温度传感器方便使用。
