DETAILED DESCRIPTION
[0034] The application is further described below in combination with the accompanying drawings and examples:
[0035] The intelligent bearing sleeve for the bearing in the gear box, as shown in Figure 9 and Figure 10 , the gap between the gear box 5 and the bearing outer ring 6 is the installation area, the gap between the gear box 5 and the bearing outer ring 6 is D, 60mm≤D≤80mm, that is, the bearing sleeve is in a narrow and closed environment, and the installation area is narrow. The intelligent bearing sleeve for the bearing in the gear box includes a bearing sleeve body 1, which is directly used in cooperation with the rolling bearing. As shown in Figure 1 , an inner recessed installation groove 1A is arranged on the outer circumferential surface of the bearing sleeve body 1, and the installation groove 1A is used for installing a core module 2. As shown in Figure 2 , the core module 2 is adapted to the installation groove 1A, that is, the shape of the core module 2 is similar to that of the installation groove 1A, and the size satisfies the condition of being installed in the installation groove 1A. As shown in Figure 3 , the core module 2 is the center of signal processing, which includes a power supply device for power supply, a signal processing device for processing signals, and a signal transmission device for receiving and transmitting signals. The core module 2 is fixed in the installation groove 1A to ensure the stability of the installation and avoid the core module 2 from falling off due to vibration and other factors.
[0036] Along the circumferential direction of the bearing sleeve body 1, a core module 2 is arranged at one end of the bearing sleeve body 1, and the core module 2 is provided with a plug hole 2A for inserting a wire 4.
[0037] A sensor 3 is further embedded on the outer circumferential surface of the bearing sleeve body 1, and the sensor 3 is used for monitoring the rolling bearing and collecting information related to the rolling bearing. When arranged, a sensor mounting hole is arranged on the bearing sleeve body 1 and penetrates the side wall of the bearing sleeve body 1 in the radial direction, and the sensor 3 is inserted into the sensor mounting hole. It is necessary to ensure that the sensor 3 is firmly installed in the sensor mounting hole to prevent the sensor from slipping off.
[0038] A wire groove 1B extending in the circumferential direction is arranged on the outer circumferential surface of the bearing sleeve body 1, and the wire groove 1B is used for laying the wire 4 to connect the sensor 3 and the core module 2. Therefore, one end of the wire groove 1B extends to the mounting groove 1A, and the other end extends to the sensor 3. One end of the wire 4 is inserted into the plug hole 2A of the core module 2, and the other end is connected with the sensor 3, so that the sensor 3 and the core module 2 communicate with each other. The relevant data of the rolling bearing monitored by the sensor 3 is transmitted to the core module 2, and the core module 2 analyzes and processes the data.
[0039] The intelligent bearing sleeve for the gearbox inner bearing integrates the core module 2, the detection sensor 3, and the wire 4 in the bearing sleeve body 1, and accommodates them in the bearing sleeve body 1. The size of the intelligent bearing sleeve is consistent with that of the conventional bearing sleeve, and 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.
[0040] During actual monitoring, the temperature, vibration, and stress of the rolling bearing need to be monitored. Therefore, the sensor 3 on the bearing sleeve body 1 includes a temperature sensor 31, a vibration sensor 32, and a pressure sensor 33. The wire groove 1B includes a wire groove one 1B1, a wire groove two 1B2, and a wire groove three 1B3 arranged side by side along the axial direction of the bearing sleeve body 1. The wire 4 installed in the wire groove one 1B1 connects the temperature sensor 31 and the core module 2. The wire 4 installed in the wire groove two 1B2 connects the pressure sensor 33 and the core module 2. The wire 4 installed in the wire groove three 1B3 connects the vibration sensor 32 and the core module 2. By independently arranging the wire grooves and independently laying 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 of each other, avoiding the problem of wire entanglement, and facilitating the stable installation of the wires 4.
[0041] The sensor 3 on the bearing sleeve body 1 has three, respectively, temperature sensor, vibration sensor and pressure sensor. In order to adapt to the installation of the wire 4, and respectively transmit the corresponding data to the core module 2, the jack 2A on the core module 2 has three. One jack 2A is inserted with a wire 4, and the other end of the three wires 4 is connected with the temperature sensor 31, the vibration sensor 32 and the pressure sensor 33 respectively.
[0042] In order to monitor the rolling bearing by area around the rolling bearing, the force condition of each area of the rolling bearing can be obtained accurately, the wire groove two 1B2 is arranged around the bearing sleeve body 1; the wire 4 along the wire groove two 1B2 is evenly arranged with N pressure sensors 33; 3≤N≤10; N test areas are formed along the bearing sleeve body 1 by the N pressure sensors 33; one pressure sensor 33 is arranged in each test area, and the pressure sensor 33 is located in the middle of the corresponding test area along the ring. Each pressure sensor 33 monitors the force of the rolling bearing in each test area, so that the force condition of each area can be obtained, and the weak position of the rolling bearing can be obtained according to the force condition of each area; the working condition change of the rolling bearing during work can be understood, and the force abnormality can be obtained through the sudden change of the detection data of the pressure sensor 33 in each test area.
[0043] The following takes N=6 as an example, as shown in the accompanying Figure 7 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 bearing sleeve body 1, it is divided into A1 test area, A2 test area, A3 test area, A4 test area, A5 test area and A6 test area; A1 pressure sensor is located in the middle of A1 test area, monitoring the force condition of rolling bearing in A1 test area; A2 pressure sensor is located in the middle of A2 test area, monitoring the force condition of rolling bearing in A2 test area; A3 pressure sensor is located in the middle of A3 test area, monitoring the force condition of rolling bearing in A3 test area; A4 pressure sensor is located in the middle of A4 test area, monitoring the force condition of rolling bearing in A4 test area; A5 pressure sensor is located in the middle of A5 test area, monitoring the force condition of rolling bearing in A5 test area; A6 pressure sensor is located in the middle of A6 test area, monitoring the force condition of rolling bearing in A6 test area. If the pressure data monitored by A1 pressure sensor is greater than the detection data of other pressure sensors, it is prompted that the rolling bearing in A1 test area is larger, and compared with other positions, it is more likely to cause deformation, damage and the like due to force. During work, if the monitoring data of one or more pressure sensors, such as A3 pressure sensor and A4 pressure sensor, is suddenly changed, it is prompted that the working condition of the equipment may be changed, or the equipment operation is abnormal, which has practicality for the accurate or rolling bearing operation.
[0044] In order to make the force 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 one 1B1 and the wire groove three 1B3 are symmetrically arranged about the wire groove two 1B2; the wire groove two 1B2 is located in the middle of the bearing sleeve body 1 along the axial direction of the bearing sleeve body 1.
[0045] Along the radial direction of the bearing sleeve body 1, the core module 2 is located inside the slot of the mounting groove 1A, that is, the slot of the mounting groove 1A is higher than the outer side surface of the core module 2, and the height is 3-8mm, and it is more appropriate to be higher than 5mm. In this way, the core module 2 is protected from being loaded by the slot of the mounting groove 1A.
[0046] Similarly, the wire 4 is located inside the slot of the wire groove 1B, that is, the slot of the wire groove 1B is higher than the wire 4, and the height is 3-8mm, and it is more appropriate to be higher than 5mm. In this way, the wire 4 is protected from being loaded by the slot of the wire groove 1B and the load is transmitted to the core module 2 and other problems.
[0047] The wire groove 1B can be a rectangular groove, but the slot of the rectangular groove is a 90° corner, and the slot is small, which is not only not conducive to the assembly of the wire 4 into the wire groove 1B, but also easy to scratch the wire 4. In order to avoid the above problems, in the embodiment, the cross section of the wire groove 1B is trapezoidal, which gradually expands from the groove bottom to the slot.
[0048] In order to facilitate the plug-in of the wire 4 and the core module 2 and the sensor, as shown in the figure, Figure 4 The wire 4 includes a wire body 41 and a plug 42 at the outer end of the wire body 41 along the length direction of the wire 4.
[0049] As shown in the figure, Figure 5 The wire body 41 includes a base body 411, a power line 412 and an information transmission line 413; the base body 411 is matched with the wire groove 1B, and the power line 412 and the information transmission line 413 are inserted into the base body 411 along the length direction of the base body 411. By forming a whole through the base body 411, the power line 412 and the information transmission line 413, the installation of the wire 4 is facilitated, and compared with the independent setting of the power line 412 and the information transmission line 413, it is more convenient to store.
[0050] In order to stabilize the wire 4 and avoid the wire 4 from falling off, the base body 411 is made of synthetic resin, which has a certain flexibility and can be assembled into the wire groove 1B by extrusion and contraction. After being assembled into the wire groove 1B, it expands by restoring the deformation, so as to be closely combined with the wire groove 1B, thereby improving the stability of the installation of the wire 4. The protrusions 41A are arranged on the two side surfaces of the base body 411. Figure 6As shown, a recessed groove 1C is provided on the inner wall of the wire groove 1B; when the wire 4 is installed in the wire groove 1B, the protrusion 41A is inserted into the groove 1C on the inner wall of the wire groove 1B. The insertion of the protrusion 41A into the groove 1C on the inner wall of the wire groove 1B serves to limit the wire 4, preventing it from falling off. In summary, in this embodiment, the flexibility of the synthetic resin matrix 44, combined with the wire groove 1B, and the mutual cooperation between the groove 1C and the protrusion 41A, achieves double fixation of the wire 4, ensuring the stable and reliable installation of the wire 4.
[0051] Since the connection between the sensor and the core module 2 is achieved by inserting the plug 42 of the wire 4 into the socket 2A of the core module 2, in order to better prevent the plug 42 of the wire 4 from coming loose during the operation of the gearbox, and to better facilitate the accurate insertion of the plug 42 into the core module 2, so as to ensure effective communication between the sensor and the core module 2, as follows: Figure 8 As shown, the socket 2A is tapered along its axial direction, gradually narrowing from the opening to the bottom. A power magnetic plate 7 and an information magnetic plate 8 are provided on the side wall of the socket 2A, with the power magnetic plate 7 and the information magnetic plate 8 arranged opposite to each other. The plug 42 is tapered to fit the socket 2A. The power line 412 and the information transmission line 413 extend to the side wall of the plug 42. The contact point of the power line 412 on the side wall of the plug 42 is magnetically connected to the power magnetic plate 7, and the contact point of the information transmission line 413 on the side wall of the plug 42 is magnetically connected to the information magnetic plate 8.
[0052] Similarly, in order to facilitate the installation of the core module 2, the installation slot 1A is a bucket shape that gradually expands outward from the bottom to the opening. The bucket shape can be a square bucket or a round bucket, etc.
[0053] like Figure 3As shown, 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 the part that directly connects to the mounting groove 1A; therefore, the housing 21 is adapted to the mounting groove 1A, meaning its shape is similar to the mounting groove 1A and it can be tightly assembled into the mounting groove 1A. The resin-made housing 21 has a certain degree of flexibility, allowing it to be assembled into the mounting groove 1A through compression and contraction. After assembly into the mounting groove 1A, it expands back to its original shape, thus tightly connecting with the mounting groove 1A and improving the stability of the core module 2 installation. The flexible housing 21 also has a certain degree of shock absorption, 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, etc., on these components. The inner wall of the housing 21, the power supply device 22, the signal processing device 23, and the signal transmission device 24 are filled with shock-absorbing material to further reduce vibration. The power supply device 22 provides the electrical energy required for the operation of components such as the signal processing device 23, the signal transmission device 24, and the sensors. The signal processing device 23 receives information collected by the sensors and processes and analyzes it. The signal transmission device 24 transmits the information collected by the sensors to the signal processing device 23 and transmits the processed information to the terminal for display, etc.
