DETAILED DESCRIPTION

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0037] As shown in Figures 9 and 10, the intelligent bearing sleeve for gearbox bearings has a mounting area defined by the gap between the gearbox 5 and the bearing outer ring 6. The gap D between the gearbox 5 and the bearing outer ring 6 is 60 mm ≤ D ≤ 80 mm, meaning the bearing sleeve is located in a confined, enclosed environment with a limited mounting area. The intelligent bearing sleeve for gearbox bearings includes a bearing sleeve body 1, which directly cooperates with the rolling bearing. As shown in Figure 1, a recessed mounting groove 1A is provided on the outer circumference of the bearing sleeve body 1. This groove is used to mount a core module 2. As shown in Figure 2, the core module 2 is compatible with the mounting groove 1A, similar in shape and sized to fit snugly within it. As shown in Figure 3, the core module 2 is the center of signal processing and includes a power supply, a signal processing unit, and a signal transmission unit for transmitting and receiving signals. The core module 2 is secured within the mounting groove 1A, ensuring stable installation and preventing it from falling out due to vibration and other factors.

[0038] Along the circumference of the bearing sleeve body 1 , a socket 2A is provided at one end of the core module 2 , and the socket 2A is used for plugging in the wire 4 .

[0039] A sensor 3 is also embedded in the outer circumference of the bearing sleeve body 1. This sensor 3 is used to monitor the rolling bearing and collect relevant information. During installation, a sensor mounting hole is provided in the bearing sleeve body 1, radially extending through the sidewall of the bearing sleeve body 1. Sensor 3 is inserted into the sensor mounting hole. Ensure that sensor 3 is securely mounted in the sensor mounting hole to prevent it from slipping.

[0040] A circumferentially extending wire groove 1B is provided on the outer circumference of the bearing housing body 1. This groove is used to route wire 4, which connects the sensor 3 and the core module 2. Thus, one end of the groove 1B extends to the mounting slot 1A, and the other end extends to the sensor 3. One end of the wire 4 is inserted into the jack 2A of the core module 2, and the other end is connected to the sensor 3, enabling communication between the sensor 3 and the core module 2. Data related to the rolling bearing monitored by the sensor 3 is transmitted to the core module 2 for analysis and processing.

[0041] The intelligent bearing sleeve for the bearing in the gearbox integrates the core module 2, the detection sensor 3 and the wire 4 into the bearing sleeve body 1, and is accommodated in the bearing sleeve body 1. The size of the intelligent bearing sleeve is consistent with that of the traditional commonly used bearing sleeve. It can be used in the narrow installation area between the gearbox 5 and the bearing outer ring 6 to monitor the bearing in the gearbox in real time.

[0042] During actual monitoring, the temperature, vibration, and stress conditions of the rolling bearing need to be monitored. Therefore, the sensors 3 on the bearing housing body 1 include a temperature sensor 31, a vibration sensor 32, and a pressure sensor 33. The wire duct 1B includes three ducts, one 1B1, one 1B2, and one 1B3, arranged axially side by side along the bearing housing body 1. The wire 4 installed in the first duct 1B1 connects the temperature sensor 31 with the core module 2; the wire 4 installed in the second duct 1B2 connects the pressure sensor 33 with the core module 2; and the wire 4 installed in the third duct 1B3 connects the vibration sensor 32 with the core module 2. By providing independent wire ducts and independently routing the wires 4 to connect the core module 2 and the corresponding sensors, the paths between each sensor and the core module 2 are independent, preventing wire entanglement and facilitating the stable installation of the control wires 4.

[0043] The bearing housing body 1 contains three sensors 3: a temperature sensor, a vibration sensor, and a pressure sensor. To accommodate the installation of wires 4 and transmit corresponding data to the core module 2, three jacks 2A are provided on the core module 2. Each jack 2A is connected to a wire 4, and the other ends of these three wires 4 are connected to the temperature sensor 31, the vibration sensor 32, and the pressure sensor 33, respectively.

[0044] To monitor the rolling bearing in different regions around the entire circumference of the bearing and accurately determine the stress conditions in each region, the second conductor channel 1B2 circumscribes the bearing housing body 1. N pressure sensors 33 are evenly arranged along the conductor 4 routing path of the second conductor channel 1B2; 3≤N≤10. These N pressure sensors 33 form N test zones circumferentially along the bearing housing body 1. Each test zone is provided with a pressure sensor 33, and each pressure sensor 33 is circumferentially located in the middle of the corresponding test zone. Each pressure sensor 33 monitors the stress conditions in each test zone, determining the stress conditions in each zone and, based on the stress conditions in each zone, identifying any weak points in the rolling bearing. Furthermore, sudden changes in the data detected by the pressure sensors 33 in each test zone can be used to understand changes in the operating conditions of the rolling bearing and detect abnormal stress conditions.

[0045] The following description takes N=6 as an example. As shown in FIG7 , the six pressure sensors 33 are respectively A1 pressure sensor, A2 pressure sensor, A3 pressure sensor, A4 pressure sensor, A5 pressure sensor, and A6 pressure sensor. Along the circumference of the bearing sleeve body 1, they are divided into A1 test area, A2 test area, A3 test area, A4 test area, A5 test area, and A6 test area. The A1 pressure sensor is located in the middle of the A1 test area to monitor the stress of the rolling bearing in the A1 test area. The A2 pressure sensor is located in the middle of the A2 test area to monitor the stress of the rolling bearing in the A2 test area. The A3 pressure sensor is located in the middle of the A3 test area to monitor the stress of the rolling bearing in the A3 test area. The A4 pressure sensor is located in the middle of the A4 test area to monitor the stress of the rolling bearing in the A4 test area. The A5 pressure sensor is located in the middle of the A5 test area to monitor the stress of the rolling bearing in the A5 test area. The A6 pressure sensor is located in the middle of the A6 test area to monitor the stress of the rolling bearing in the A6 test area. If the pressure data monitored by the A1 pressure sensor is greater than the detection data of other pressure sensors, it indicates that the rolling bearing is subjected to greater force in the A1 test area, and is more likely to be deformed or damaged due to force compared to other locations. During operation, if the monitoring data of one or more pressure sensors, such as the A3 pressure sensor and the A4 pressure sensor, suddenly changes, it indicates that the working condition of the equipment may have changed or the equipment operation is abnormal, which is practical for accurately monitoring the operation of the rolling bearing.

[0046] In order to make the force application point of the bearing sleeve located in the middle of the bearing sleeve body 1 along the axial direction of the bearing sleeve body 1, preferably, the wire groove 1B1 and the wire groove 3 1B3 are symmetrically arranged about the wire groove 2 1B2; the wire groove 2 1B2 is located in the middle of the bearing sleeve body 1 along the axial direction of the bearing sleeve body 1.

[0047] Along the radial direction of the bearing sleeve body 1, the core module 2 is located inside the notch of the mounting groove 1A. That is, the notch of the mounting groove 1A protrudes above the outer surface of the core module 2. The protrusion range is 3-8 mm, and generally above 5 mm is suitable. This arrangement prevents the core module 2 from being subjected to load due to protrusion above the notch of the mounting groove 1A, thereby providing a certain degree of protection for the core module 2.

[0048] Similarly, wire 4 is located inside the notch of wire trough 1B, i.e., the notch of wire trough 1B is higher than wire 4, with the height range of 3-8 mm, and usually higher than 5 mm being more appropriate. This arrangement avoids the problem of wire 4 being higher than the notch of wire trough 1B and bearing load and transmitting the load to core module 2.

[0049] Wire duct 1B can be a rectangular duct, for example. However, the opening of a rectangular duct is at a 90° angle, resulting in a small opening. This not only makes it difficult to fit wires 4 into duct 1B but also easily scratches the wires 4. To avoid these issues, in this embodiment, the cross-section of wire duct 1B is a trapezoidal shape that gradually expands from the bottom to the opening.

[0050] In order to facilitate the connection between the wire 4 and the core module 2 and the sensor, as shown in FIG4 , the wire 4 includes a wire body 41 and a plug 42 located at the outer end of the wire body 41 along its length direction.

[0051] As shown in Figure 5, the conductor body 41 includes a base 411, a power cord 412, and an information transmission line 413. The base 411 is adapted to fit within the conductor duct 1B, and the power cord 412 and information transmission line 413 are inserted into the base 411 along the length of the base 411. The base 411, power cord 412, and information transmission line 413 form a single unit, facilitating installation of the conductor 4 and making storage easier than if the power cord 412 and information transmission line 413 were provided separately.

[0052] To stabilize the wire 4 and prevent it from falling out, the base 411 is made of synthetic resin with a certain degree of flexibility. It can be squeezed and contracted to fit into the wire trough 1B. Once assembled, it recovers its deformation and expands, tightly fitting into the trough 1B and enhancing the secure installation of the wire 4. Outwardly projecting bumps 41A are provided on both sides of the base 411. As shown in Figure 6, a recessed groove 1C is provided on the inner sidewall of the wire trough 1B. When the wire 4 is installed in the wire trough 1B, the bumps 41A engage with the groove 1C on the inner sidewall of the wire trough 1B. The engagement of the bumps 41A with the groove 1C on the inner sidewall of the wire trough 1B acts as a retaining force on the wire 4, preventing it from falling out. In summary, in this embodiment, the flexibility of the synthetic resin base 44, combined with the wire trough 1B, and the interaction between the groove 1C and the bumps 41A, achieve dual fixation of the wire 4, ensuring secure and reliable installation of the wire 4.

[0053] Since the connection between the sensor and the core module 2 is achieved by inserting the plug 42 of the wire 4 into the jack 2A of the core module 2, in order to better avoid the plug 42 of the wire 4 from being pulled out during the operation of the gearbox, and to facilitate the accurate connection of the plug 42 and the core module 2 to ensure effective communication between the sensor and the core module 2, as shown in Figure 8, the jack 2A is tapered along its axial direction, gradually converging from the hole mouth to the bottom of the hole, and a power magnetic sheet 7 and an information magnetic sheet 8 are provided on the side wall of the jack 2A, and the power magnetic sheet 7 and the information magnetic sheet 8 are arranged opposite to each other; the plug 42 is tapered to match the jack 2A, and the power line 412 and the information transmission line 413 extend to the side wall of the plug 42, and the power line 412 is magnetically connected to the power magnetic sheet 7 at the contact on the side wall of the plug 42, and the information transmission line 413 is magnetically connected to the information magnetic sheet 8 at the contact on the side wall of the plug 42.

[0054] Similarly, in order to facilitate the installation of the core module 2, the installation slot 1A is in a bucket shape that gradually expands outward from the bottom of the slot to the slot mouth. The bucket shape here can be a square bucket or a circular bucket.

[0055] As shown in Figure 3, the core module 2 includes a housing 21, a power supply unit 22, a signal processing unit 23, and a signal transmission unit 24. The housing 21 is directly connected to the mounting slot 1A. Therefore, the housing 21 is compatible with the mounting slot 1A, that is, its shape is similar to the mounting slot 1A and can fit tightly within the mounting slot 1A. Made of resin, the housing 21 has a certain degree of flexibility and can be assembled into the mounting slot 1A through compression and contraction. Once assembled into the mounting slot 1A, it recovers its deformation and expands, thus tightly fitting into the mounting slot 1A and enhancing the stability of the core module 2 installation. The flexible housing 21 also has certain shock-absorbing properties, reducing the impact of vibration on the internal power supply unit 22, signal processing unit 23, and signal transmission unit 24. Furthermore, the housing 21 encloses the power supply unit 22, signal processing unit 23, and signal transmission unit 24, reducing the impact of dust, grease, and other factors on the power supply unit 22, signal processing unit 23, and signal transmission unit 24. The inner walls of the housing 21, the power supply unit 22, the signal processing unit 23, and the signal transmission unit 24 are filled with shock-absorbing material to further reduce vibration. The power supply unit 22 supplies the electrical energy required for the operation of components such as the signal processing unit 23, the signal transmission unit 24, and the sensors. The signal processing unit 23 receives and processes information collected by the sensors. The signal transmission unit 24 transmits the information collected by the sensors to the signal processing unit 23 and transmits the processed information to the terminal for display.
