Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a mounted spherical ball bearing. Background Technology

[0002] Bearings are the supports for mechanical transmission shafts and are an important guarantee for realizing the performance, function and efficiency of the main machine. They are known as the joints of the machine. Spherical roller bearings, also known as outer spherical bearings, belong to deep groove ball bearings. The rolling elements inside are steel balls, and the outer ring surface is spherical, hence the name outer spherical roller bearing.

[0003] In the prior art, during the use of mounted spherical roller bearings, if the balls inside the bearing shift, it will cause changes in the pressure on the inner wall of the bearing. If this is not detected and adjusted in time, it will cause wear inside the bearing, thereby affecting the service life of the bearing. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, during the use of mounted spherical roller bearings, if the balls inside the bearing shift, it will cause changes in the pressure on the inner wall of the bearing. If this is not detected and adjusted in time, it will cause wear inside the bearing, thus affecting the service life of the bearing. Therefore, this invention proposes a mounted spherical roller bearing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mounted spherical roller bearing includes a housing and an outer spherical roller bearing. The housing is slidably fitted onto the outer side of the outer spherical roller bearing. Multiple balls are rolled around the outer surface of the outer spherical roller bearing. A box is fixedly connected to the top of the housing. A controller is fixedly connected to the inner wall of the box. A wire is electrically connected to the bottom of the controller. Multiple notches are formed around the inner wall of the housing. Pressure sensors are fixedly connected to the inner walls of the multiple notches. The ends of the wires away from the controller are electrically connected to the multiple pressure sensors. A pressure-sensing plate is slidably mounted on the inner wall of the notch of the housing. A metal elastic strip is fixedly connected to the side wall of the pressure-sensing plate. The end of the metal elastic strip away from the pressure-sensing plate is fixedly connected to the inner wall of the notch. Multiple alarms are electrically connected to the top of the controller.

[0007] Preferably, the outer spherical ball bearing has a reinforcing sleeve fixedly connected to the inner wall of the multiple balls, the multiple balls are respectively rolled on the inner wall of the reinforcing sleeve, and multiple reinforcing fins are fixedly connected around the outer side of the multiple reinforcing sleeves.

[0008] Preferably, the connection between the controller and the housing is also threaded with a mounting support frame.

[0009] Preferably, a pressure block is fixedly connected to the top of the pressure-sensing plate, and the pressure block is aligned with the pressure sensor.

[0010] Preferably, the housing has a guide groove on the inner wall of the recess, a guide slider is fixedly connected to the side wall of the pressure-sensing plate, the guide slider is slidably disposed on the inner wall of the guide groove, and a sealing rubber gasket is fixedly connected to the bottom of the pressure-sensing plate.

[0011] Preferably, the bottom inner wall of the housing is threaded with mounting bolts.

[0012] Compared with the prior art, this utility model provides a mounted spherical ball bearing, which has the following advantages:

[0013] 1. This mounted spherical roller bearing works by transmitting pressure through the housing to a pressure-sensing plate when the bearing is subjected to external load. The pressure-sensing plate deforms by squeezing the metal elastic strip under pressure, and slides within a recess, aligning with the pressure sensor via a top-mounted pressure block. This accurately transmits the pressure to the sensor, which converts the detected pressure into an electrical signal, which is then transmitted to the controller via a wire. When the controller detects that the pressure exceeds a preset threshold, it immediately sends a signal to the alarm, which then sounds an alarm, alerting staff to promptly inspect and address the issue, thus preventing bearing damage and equipment malfunction.

[0014] 2. This mounted spherical roller bearing enhances the overall strength of the bearing through the reinforcing sleeve on the inner wall of the spherical roller bearing. Multiple balls roll on the inner wall of the reinforcing sleeve, reducing direct wear on the bearing body. The reinforcing fins on the outer side of the reinforcing sleeve increase the force-bearing area, further improving the bearing's load-bearing capacity and stability, enabling it to withstand greater loads.

[0015] 3. The mounted spherical roller bearing moves within the guide groove via a guide slider on the side wall of the pressure-sensing plate, ensuring the stability of the pressure-sensing plate's movement. The sealing rubber gasket at the bottom of the pressure-sensing plate prevents dust, moisture, and other impurities from entering the recess, protecting the pressure sensor and metal elastic strip and extending their service life. The mounting bolts on the inner wall of the bottom of the housing are used to fix the bearing to the equipment, ensuring that the bearing will not loosen during operation. The controller is connected to the housing via a mounting support frame, ensuring that the controller is securely installed and operates stably. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A mounted spherical roller bearing includes a housing 1 and an outer spherical roller bearing 2. The housing 1 is slidably sleeved on the outside of the outer spherical roller bearing 2. Multiple balls 3 are rolled around the outer surface of the outer spherical roller bearing 2. A box 6 is fixedly connected to the top of the housing 1. A controller 7 is fixedly connected to the inner wall of the box 6. A wire 9 is electrically connected to the bottom of the controller 7. Multiple recesses are opened around the inner wall of the housing 1. Pressure sensors 10 are fixedly connected to the inner walls of the multiple recesses respectively. The end of the wire 9 away from the controller 7 is electrically connected to the multiple pressure sensors 10 respectively. A pressure-sensing plate 12 is slidably mounted on the inner wall of the recess of the housing 1. A metal elastic strip 11 is fixedly connected to the side wall of the pressure-sensing plate 12. The end of the metal elastic strip 11 away from the pressure-sensing plate 12 is fixedly connected to the inner wall of the recess. Multiple alarms 17 are electrically connected to the top of the controller 7.

[0022] The outer spherical ball bearing 2 is fixedly connected to the inner wall of multiple balls 3 by reinforcing sleeves 4. The multiple balls 3 are rolled on the inner wall of the reinforcing sleeves 4. Multiple reinforcing fins 5 are fixedly connected around the outer side of the multiple reinforcing sleeves 4. The connection between the controller 7 and the housing 6 is threaded with a mounting support bracket 8. The top of the pressure plate 12 is fixedly connected to a pressure block 13, which is aligned with the pressure sensor 10.

[0023] In use, when the outer spherical ball bearing 2 bears an external load, the pressure is transmitted to the pressure-sensing plate 12 through the housing 1. After being subjected to force, the pressure-sensing plate 12 squeezes the metal elastic strip 11, causing the metal elastic strip 11 to undergo elastic deformation. The pressure-sensing plate 12 slides in the recess, and the pressure block 13 at the top of the pressure-sensing plate 12 aligns with the pressure sensor 10, accurately transmitting the pressure to the pressure sensor 10. The pressure sensor 10 converts the sensed pressure into an electrical signal, which is transmitted to the controller 7 through the wire 9. The controller 7 analyzes and processes the electrical signal to determine whether the pressure borne by the bearing is within the normal range. When the controller 7 detects that the pressure exceeds the preset threshold, it indicates that the bearing may be overloaded, worn, or otherwise abnormal. The controller 7 immediately sends a signal to the alarm 17, which sounds an alarm to remind the staff to check and handle the situation in a timely manner to avoid bearing damage and equipment failure.

[0024] The reinforcing sleeve 4 on the inner wall of the outer spherical ball bearing 2 enhances the overall strength of the bearing. Multiple balls 3 roll on the inner wall of the reinforcing sleeve 4, reducing direct wear on the bearing body. The reinforcing fins 5 on the outer side of the reinforcing sleeve 4 increase the force-bearing area, further improving the bearing's load-bearing capacity and stability, enabling it to withstand greater loads.

[0025] To prevent dust, moisture, and other impurities from entering the recess, such as Figure 1-3 As shown, the inner wall of the housing 1 within the recess has a guide groove. A guide slider 14 is fixedly connected to the side wall of the pressure-sensing plate 12. The guide slider 14 is slidably disposed within the inner wall of the guide groove. A sealing rubber gasket 15 is fixedly connected to the bottom of the pressure-sensing plate 12. A mounting bolt 16 is threadedly connected to the inner wall of the bottom end of the housing 1.

[0026] The guide slider 14 on the side wall of the pressure plate 12 moves within the guide groove to ensure the stability of the pressure plate 12's movement. The sealing rubber pad 15 at the bottom of the pressure plate 12 prevents dust, moisture, and other impurities from entering the recess, protecting the pressure sensor 10 and the metal elastic strip 11 and extending their service life. The mounting bolts 16 on the inner wall of the bottom end of the housing 1 are used to fix the bearing to the equipment, ensuring that the bearing will not loosen during operation. The controller 7 is threadedly connected to the housing 6 through the mounting support bracket 8, ensuring that the controller 7 is firmly installed and works stably.
