[0020] Embodiment 1:

[0021] Please refer to Figures 1-6 : In this embodiment, a load measuring device for the production of a stern shaft bearing includes a stern shaft bearing body 1 and a workbench 2. The upper end of the workbench 2 is fixedly connected to a mounting seat 3, and the upper end of the mounting seat 3 is fixedly connected to a first mounting bracket 4. A servo motor 5 is installed on the outer wall of the first mounting bracket 4. The model of the servo motor 5 can be determined according to actual needs as long as it meets the work requirements. The output end of the servo motor 5 is fixedly connected to a thrust shaft 6, and a support mechanism 7 is connected to the outer wall of the thrust shaft 6.

[0022] The support mechanism 7 includes an arc plate 701. By sliding the arc plate 701 and an arc ring 702, the external sizes of the arc plate 701 and the arc ring 702 are changed, achieving the effect of supporting the shaft bearing body 1 by the arc plate 701 and the arc ring 702. The inner wall of the arc plate 701 meshes with the thrust shaft 6. The outer wall of the arc plate 701 is slidably connected to the arc ring 702. The inner wall of the arc ring 702 is threadedly connected to a fixing screw 703, and the outer wall of the fixing screw 703 is threadedly connected to the arc plate 701;

[0023] The servo motor 5 drives the arc plate 701 and the arc ring 702 on the thrust shaft 6 to rotate, causing the arc ring 702 to drive the stern tube bearing inside the stern shaft bearing body 1 to rotate. The hydraulic cylinder 802 will synchronously push the sliding frame 801 to move leftward, causing the sliding frame 801 to drive the movement state between the stern shaft bearing body 1 and the thrust shaft 6 to form a leftward load. Observe the value generated by the sliding frame 801 pressing the pressure gauge 803, and the rotation speed displayed by the tachometer 10 on the connecting piece 11 driven by the thrust shaft 6. There is no need to push by itself, and the load measurement of the stern shaft bearing body 1 can be obtained more accurately and quickly, and the work efficiency will also be improved.

[0024] The outer wall of the arc-shaped ring 702 abuts against the stern shaft bearing body 1. A load measuring mechanism 8 is connected to the lower end of the stern shaft bearing body 1. The load measuring mechanism 8 includes a sliding frame 801. The sliding frame 801 is pushed by a hydraulic cylinder 802 to slide on the mounting base 3, so that the sliding frame 801 forms the effect of load thrust.

The outer wall of the sliding frame 801 abuts against a pressure device 803.

[0025] Working principle:

[0026] Preparation stage

[0027] The stern shaft bearing body 1 is passed through the thrust shaft 6 from the left end. Then, the arc-shaped plate 701 and the arc-shaped ring 702 are sleeved on the thrust shaft 6, and the distance between the arc-shaped plate 701 and the arc-shaped ring 702 is adjusted so that the outer wall of the arc-shaped ring 702 abuts tightly against the inner wall of the stern shaft bearing body 1. At the same time, the fixing screw 703 is screwed through the arc-shaped plate 701 and the arc-shaped ring 702 for fixation, and the end of the fixing screw 703 will abut tightly against the thrust shaft 6 for secondary fixation. The second mounting bracket 9 is fixed to the mounting base 3 by using an external bolt-tightening method, and it is confirmed that the thrust shaft 6 enters the inside of the connecting member 11 for engagement. The preparation work is completed.

[0028] Embodiment 2:

[0029] Please refer to Figures 1-6 : In this embodiment, the upper end of the mounting base 3 is fixedly connected to the pressure device 803. The model of the pressure device 803 is US10000 pressure sensor. The upper end of the mounting base 3 is fixedly connected to the hydraulic cylinder 802.

The output end of the speed detector 10 is fixedly connected to the connecting member 11. The inner wall of the connecting member 11 meshes with the thrust shaft 6.

[0030] Measurement stage

[0031] By connecting the external power supply of the servo motor 5, the servo motor 5 drives the arc-shaped plate 701 and the arc-shaped ring 702 on the thrust shaft 6 to rotate, so that the arc-shaped ring 702 drives the stern tube bearing inside the stern shaft bearing body 1 to rotate. At the same time, control the hydraulic cylinder 802 to open. The hydraulic cylinder 802 will push the sliding frame 801 to move leftward, so that the sliding frame 801 drives the movement state between the stern shaft bearing body 1 and the thrust shaft 6 to form a leftward load, and observe the value generated by the sliding frame 801 pressing the pressure device 803, as well as the rotational speed displayed by the speedometer 10 on the connecting piece 11 driven by the thrust shaft 6.
