Description

Technical Field

[0002] The primary function of an intermediate bearing radial load measurement device is to monitor and measure the radial load on a bearing in real time during operation. Radial load refers to the force applied to the bearing perpendicular to the axis of the shaft. This force typically originates from factors such as the equipment's workload, operating speed, and vibration. Bearings support rotating components and withstand the forces they generate. Therefore, monitoring their radial load is crucial for assessing the bearing's operating condition and health, as well as predicting the equipment's remaining service life. However, an existing intermediate bearing radial load measurement device (Announcement No.: CN220270792U) suffers from the following shortcomings during use:

[0003] This measurement device can only be used in standard environments (such as room temperature and normal humidity). Bearings need to operate under different environmental conditions, such as high temperature, low temperature, and high humidity. If the test environment cannot be changed, the performance of the bearing in actual application cannot be fully evaluated. The test results may differ significantly from the actual performance in application and may not accurately reflect the load and durability of the bearing in extreme environments. Therefore, this patent proposes a radial load measurement device for intermediate bearings to solve the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The main function of the intermediate bearing radial load measuring device is to monitor and measure the radial load of the bearing in real time during operation. Radial load refers to the force applied to the bearing perpendicular to the axis of the shaft, which usually comes from factors such as the equipment's workload, operating speed, and vibration. The function of the bearing is to support the rotating parts and withstand the forces generated by them. Therefore, monitoring its radial load is crucial for evaluating the working condition and health of the bearing and predicting the remaining service life of the equipment. The intermediate bearing radial load measuring device provided by the present invention can be set to a low temperature, high temperature, and high humidity environment, so as to facilitate the measurement of the radial load data of the intermediate bearing 18 in different environments, comprehensively evaluate the performance of the bearing in actual applications, and more accurately reflect the load and durability of the bearing in extreme environments.

[0020] like Figure 1-Figure 4As shown, the utility model provides a technical solution: an intermediate bearing radial load measuring device, including a box body 1 and an intermediate bearing 18, the intermediate bearing 18 includes a bearing seat, a bearing inner ring and a bearing outer ring, the bearing outer ring is a static component, the bearing inner ring is a moving component, the bearing seat is located on the outside of the bearing outer ring, a box door 2 is installed on the front of the box body 1, a movable frame 11 is slidably connected inside the box body 1, the bearing seat can be installed in the movable frame 11 through a mounting plate, a heating box 6 and a cooling box 7 are fixed on the back of the box body 1, a hot air blower is installed in the heating box 6, A refrigerator is installed in the refrigeration box 7, a first connecting port 10 is provided between the heating box 6 and the box body 1, a second connecting port is provided between the refrigeration box 7 and the box body 1, a first connecting pipe 8 is fixedly connected to the rear side of the heating box 6, and a second connecting pipe 9 is fixedly connected to the rear side of the refrigeration box 7. The first connecting pipe 8 and the second connecting pipe 9 pass through the box body 1 and are fixedly connected to the bottom end of the movable rack 11. A humidifier 4 is fixed on one side of the box body 1, and the top of the humidifier 4 is fixedly connected to the delivery pipe 5. The delivery pipe 5 passes through the box body 1 and is fixedly connected to the top of the movable rack 11.

[0021] It should be noted that, by setting up the hot air blower, the refrigerator and the humidifier 4, when the mobile frame 11 moves upward, the hot air blower is started, and the hot air enters the mobile frame 11 through the first connecting port 10; when the mobile frame 11 moves downward, the refrigerator is started, and the cold air enters the mobile frame 11 through the second connecting port; and by starting the humidifier 4, moisture enters the mobile frame 11 through the conveying pipe 5, so that the intermediate bearing 18 in the mobile frame 11 can be subjected to radial load measurement in high temperature, low temperature and high humidity environments, thereby comprehensively evaluating the performance of the bearing in actual application, and more accurately reflecting the load and durability of the bearing in extreme environments. In addition, the first connecting pipe 8, the second connecting pipe 9 and the conveying pipe 5 are all hoses.

[0022] like Figure 4 As shown, a fixed plate 14 is fixed between the top inner wall and the bottom inner wall of the movable frame 11. The movable frame 11 and the fixed plate 14 are both made of heat-insulating materials. One side of the fixed plate 14 is rotatably connected to the first transmission rod 16, and the inner wall of one side of the movable frame 11 is rotatably connected to the second transmission rod 17. The intermediate bearing 18 is arranged between the first transmission rod 16 and the second transmission rod 17. The inner ring of the intermediate bearing 18 is fixed to the first transmission rod 16 and the second transmission rod 17. The other side of the fixed plate 14 is fixed to the first motor 15. The output end of the first motor 15 passes through the fixed plate 14 and is fixed to the first transmission rod 16.

[0023] It should be noted that by starting the first motor 15, the first motor 15 drives the first transmission rod 16 to rotate, and the rotation of the first transmission rod 16 drives the inner ring of the intermediate bearing 18 to rotate, and then drives the second transmission rod 17 to rotate, thereby facilitating the measurement of the radial load data of the intermediate bearing 18 in the working state.

[0024] like Figure 4 As shown, a screw rod 12 is rotatably connected between the top inner wall and the bottom inner wall of the box body 1. A slider 13 is screwed to the outer wall of the screw rod 12. The slider 13 is fixed to one side of the movable frame 11. A second motor is fixed to the top of the box body 1. The output end of the second motor passes through the box body 1 and is fixed to the screw rod 12. A slide groove is opened on the other side of the movable frame 11. A limit bar is fixed to the inner wall of the box body 1, and the limit bar is adapted to the slide groove.

[0025] It should be noted that by starting the second motor, the second motor drives the screw rod 12 to rotate, and the screw rod 12 drives the movable frame 11 to move, so that the movable frame 11 can move up and down in the box body 1, and then switch between the cooling and heating areas.

[0026] like Figure 4 As shown, a strain gauge is mounted on the outside of intermediate bearing 18, which is mounted on the bearing seat. A mounting hoop 19 is mounted on the outside of intermediate bearing 18, which is mounted on the bearing seat. A protective shell 20 is mounted on mounting hoop 19, which is located outside the strain gauge. A temperature sensor and a humidity sensor are mounted on the top inner wall of mobile frame 11. A controller 3 is mounted on the other side of housing 1. Controller 3 is electrically connected to the air heater, refrigerator, humidifier 4, first motor 15, second motor, temperature sensor, and humidity sensor.

[0027] It's important to note that when the bearing is subjected to force, the surface to which the strain gauge is attached will deform slightly, causing the strain gauge's resistance to change. These changes are converted into load data via a bridge circuit. Protective housing 20 protects the strain gauge from moisture, while temperature and humidity sensors monitor the temperature and humidity within mobile frame 11. The specific connection methods and operating principles of these various electrical components are well known in the art and are not detailed here.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
