[0020] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a force measuring tool for the intermediate bearing of a ship shaft system includes a force measuring machine 1 and a support body assembly 2, wherein the support body assembly includes a shell 21, and also includes a sensing head 22, which is arranged in the shell and electrically connected to the force measuring machine, a connecting column 23, which is arranged on the outer wall of the shell, partially passes through the through hole of the bearing 9 and is provided with a detachably connected support plate 24, and the support plate contacts the bottom end surface of the bearing; a push rod 25, which is retractably arranged on the shell, part of the push rod is arranged in the shell and opposite to the sensing head, and part of the push rod extends out of the shell. When in use, a pair of force measuring sensor supports are diagonally installed in the mounting bolt holes on the left and right sides of the intermediate bearing, and the center of the intermediate bearing is adjusted to the original height position through the support body. After starting the device, the load of the intermediate bearing is directly detected, which overcomes the disadvantage of large errors in the indirect measurement of the intermediate bearing load in the past. The principle is that the intermediate bearing is carried by the support plate, and the housing is driven to move downward relative to the push rod. The push rod supports the sensor head (the sensor head moves downward with the housing) and supports the pressure of the sensor head. The value can be read from the dynamometer.

[0021] In this embodiment, as shown in the figure, the support plate is a nut, and the outer wall of the connecting column is provided with a thread matched with the nut. The connecting column passes through and then connects to the nut, and the nut is used to support the bearing.

[0022] In this embodiment, as shown in the figure, the housing is provided with a slide groove 211, part of the push rod is in clearance with the slide groove, and the push rod arranged in the housing is provided with a retaining ring 251 which is in blocking cooperation with the slide groove. The relative movement between the push rod and the housing is facilitated, and the retaining ring plays a guiding role, and can prevent the push rod from falling out.

[0023] In this embodiment, as shown in the figure, the sensing head is installed in the housing by fasteners. The sensing head can be a pressure sensor, which can be installed in the housing by screws or the like.

[0024] In this embodiment, as shown in the figure, the housing includes a detachably connected upper housing 201 and a lower housing. The upper housing and the lower housing can also be installed by screws, which is convenient for installing internal parts when disassembled.

[0025] In this embodiment, as shown in the figure, the lower shell includes a base 203, and the connecting column is provided on the base.

[0026] In this embodiment, as shown in the figure, a spring 204 is also included, and the spring is arranged between the base and the bearing to play the role of pre-tightening and supporting.
