[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This application provides a bearing axial load monitoring device, which solves the problems of existing monitoring devices, which are complex in structure, cumbersome in installation and debugging, increasing the cost and time of use, and are prone to low monitoring accuracy. If the strain gauge is misaligned or slips, the measurement results will be inaccurate, affecting the measurement accuracy and monitoring stability, and causing inconvenience to the monitoring work.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example

[0033] This utility model discloses a bearing axial load monitoring device, according to the attached... Figure 1-6 As shown, it includes a bearing bracket 1, a monitoring rod 2, a fixed frame 3, a movable rod 4, a pressure sensor body 5, and a controller 6;

[0034] The bearing bracket 1 is positioned at the target support location and has a main shaft 11 on it for supporting the bearing body 12. The bearing bracket 1 supports the bearing body 12 via the main shaft 11, ensuring the stability of the bearing during operation. Simultaneously, the bearing bracket 1 also serves as the mounting base for other components.

[0035] The monitoring rod 2 is slidably connected to the bearing bracket 1 and aligned with the side of the bearing body 12; when the bearing body 12 is subjected to axial load, the monitoring rod 2 will slide accordingly, and the amount of sliding reflects the magnitude of the axial load of the bearing.

[0036] The fixing frame 3 is mounted on the bearing bracket 1, and a first spring 31 is connected to the fixing frame 3; the first spring 31 is used to apply a preload to the movable rod 4 to ensure that the movable rod 4 maintains a certain contact pressure with the monitoring rod 2 in the initial state.

[0037] The movable rod 4 is slidably connected to the fixed frame 3. The movable rod 4 is provided with a mounting seat 41, which is connected to the first spring 31. The movable rod 4 moves with the sliding action of the monitoring rod 2 and transmits pressure to the pressure sensor body 5 through the mounting seat 41.

[0038] The pressure sensor body 5 is mounted on the mounting base 41 and contacts the movable rod 4. A cable 51 is mounted on the pressure sensor body 5. The pressure sensor body 5 is used to detect the pressure transmitted from the movable rod 4 and convert it into an electrical signal. The cable 51 is used to transmit the electrical signal to the controller 6.

[0039] The controller 6 is located at the personnel monitoring position and connected to the cable 51. The controller 6 receives the electrical signals transmitted from the pressure sensor body 5, and processes, displays, and alarms accordingly.

[0040] The bearing bracket 1 is provided with a limiting unit 7 for limiting the position of the monitoring rod 2. The limiting unit 7 includes:

[0041] Sleeve 71 is mounted on bearing bracket 1;

[0042] The slider 72 is fixedly connected to the monitoring rod 2 and slidably connected inside the sleeve 71;

[0043] The second spring 73 is disposed between the slider 72 and the sleeve 71.

[0044] The limiting unit 7 is used to limit the sliding range of the monitoring rod 2 to prevent it from being damaged due to excessive sliding. The second spring 73 is used to apply a preload to the slider 72, so that the monitoring rod 2 is always in the initial position and that the monitoring rod 2 does not contact the bearing body 12, leaving a gap to prevent the vibration of the bearing body 12 during normal use from triggering the movement of the monitoring rod 2 and causing false alarms.

[0045] The controller 6 is equipped with a display screen 61 and an alarm 62. Both the display screen 61 and the alarm 62 are located on the controller 6. The display screen 61 is used to display real-time data of the bearing axial load, and the alarm 62 is used to issue an alarm signal when the bearing axial load exceeds a set threshold. Example

[0046] This utility model discloses a bearing axial load monitoring device, according to the attached... Figure 1-6 As shown, it includes a bearing bracket 1, a monitoring rod 2, a fixed frame 3, a movable rod 4, a pressure sensor body 5, and a controller 6;

[0047] The bearing bracket 1 is located at the target support position and is provided with a main shaft 11 for supporting the bearing body 12.

[0048] The monitoring rod 2 is slidably connected to the bearing bracket 1 and aligned with the side of the bearing body 12;

[0049] The fixing frame 3 is mounted on the bearing bracket 1, and the first spring 31 is connected to the fixing frame 3;

[0050] The movable rod 4 is slidably connected to the fixed frame 3. The movable rod 4 is provided with a mounting seat 41, which is connected to the first spring 31.

[0051] The pressure sensor body 5 is mounted on the mounting base 41, and the pressure sensor body 5 is in contact with the movable rod 4. A cable 51 is provided on the pressure sensor body 5.

[0052] The controller 6 is located at the personnel monitoring position and connected to the cable 51.

[0053] The mounting base 41 has a lateral support rod 42 on its side, which is slidably connected to the fixing frame 3.

[0054] A support sleeve 43 is connected to the bearing bracket 1, and a lateral support rod 42 is slidably connected to the support sleeve 43. The lateral support rod 42 and the support sleeve 43 are used to provide lateral support for the movable rod 4, thereby improving the stability and anti-tilting ability of the movable rod 4.

[0055] The operating steps for this bearing axial load monitoring device are as follows:

[0056] When the bearing body 12 is started, the bearing body 12 begins to rotate.

[0057] When the bearing body 12 does not experience axial load offset, the monitoring rod 2 is in normal condition and the pressure sensor body 5 is in the initial value state.

[0058] When the bearing body 12 experiences axial load displacement, the monitoring rod 2 slides under the axial load of the bearing body 12 and transmits the pressure to the pressure sensor body 5 through the movable rod 4.

[0059] The pressure sensor body 5 converts the pressure into an electrical signal, which is then transmitted to the controller 6 via cable 51.

[0060] The controller 6 receives electrical signals and processes, displays, and alarms. When the axial load on the bearing exceeds the set threshold, the alarm 62 issues an alarm signal.
