Description

Technical Field

[0001] This utility model relates to the field of bearing operation monitoring technology, specifically a self-aligning roller bearing operation thermal effect monitoring mechanism. Background Technology

[0002] Monitoring the thermal effects of self-aligning roller bearings is of great significance. During operation, bearings generate heat due to friction and other factors. If this thermal effect gets out of control, it can accelerate grease aging, reduce bearing precision, and even cause equipment failure and downtime. By monitoring the thermal effect in real time, abnormal changes in the bearing's operating status can be detected promptly, providing early warnings of potential faults. This not only avoids production interruptions caused by sudden bearing failure and reduces economic losses, but also allows for the rational planning of maintenance schedules, extends bearing life, and ensures long-term stable operation of equipment, playing a crucial role in improving industrial production efficiency and reliability.

[0003] The utility model with announcement number CN222850183U discloses a wind turbine bearing temperature monitoring and analysis device. This utility model solves the problem that existing wind turbine bearing temperature monitoring uses handheld infrared thermometers, which may not be able to achieve continuous monitoring, resulting in the inability to obtain real-time bearing temperature changes and missing critical fault warnings. Its structure includes a bearing housing, with a base plate movably installed inside the bearing housing. The base plate includes an annular T-groove B, a guide component, an arc groove, and a monitoring component. The monitoring component includes a sliding plate, a motor housing, rollers, a base, and a laser thermometer, achieving a more complete effect of bearing temperature monitoring.

[0004] While the aforementioned analytical device can detect the temperature of bearings by moving a laser thermometer, its complex structure and the extremely precise fit required for its moving parts make it very difficult to manufacture. Furthermore, the poor disassembly of the overall structure makes maintenance extremely difficult in case of malfunction, resulting in high costs and hindering its widespread adoption. Therefore, to address these issues, a self-aligning roller bearing working thermal effect monitoring mechanism is proposed. Utility Model Content

[0005] To address the technical problem that the complex structure of bearing operation monitoring devices in comparative technologies leads to high operating costs and maintenance difficulties, hindering widespread adoption, this utility model provides a self-aligning roller bearing operation thermal effect monitoring mechanism.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A self-aligning roller bearing working thermal effect monitoring mechanism includes a monitoring mounting base with bearing bodies embedded at both ends. The monitoring mounting base has a monitoring cavity, and mounting ports communicating with the monitoring cavity are opened on both sides of the monitoring mounting base. Mounting holes corresponding to the positions of the bearing bodies are opened on both sides of the mounting ports. A thermal imaging monitoring frame is inserted into the mounting port, and its working end extends into the monitoring cavity facing the bearing body. A contact-type temperature sensing component is inserted into the mounting hole, and its working end is in contact with the outer ring of the bearing body.

[0008] In one possible implementation, the thermal imaging monitoring frame includes a mounting cover plate with symmetrically arranged support rods fixedly disposed on its inner end face. The front end of the support rods is fixedly connected to a snap-fit ​​mounting bracket, wherein symmetrically arranged thermal imaging probes are snap-fitted and mounted thereon.

[0009] In one possible implementation, the snap-fit ​​mounting bracket has mounting slots at both ends, the size of which matches the outer size of the thermal imaging probe, and the entire snap-fit ​​mounting bracket is made of elastic material.

[0010] In one possible implementation, the inner end face of the mounting cover is fixedly provided with a plug frame that matches the size of the mounting opening, and a connecting shaft is fixedly provided at each of the four corners of the inner end face of the mounting cover. The outer side of the mounting monitoring seat is provided with a positioning slot that surrounds the mounting opening, the size of which matches the size of the mounting cover, and a positioning groove corresponding to the connecting shaft is provided at each of the four corners of the positioning slot.

[0011] In one possible implementation, the mounting cover and snap-fit ​​mounting bracket are provided with a set of cable grooves, and the cable of the thermal imaging probe is arranged along the cable grooves.

[0012] In one possible implementation, the contact-type temperature sensing component includes a closed cover with a temperature sensing probe fixedly disposed on its inner end face. The end of the temperature sensing probe is in contact with the outer ring of the bearing body, wherein the gap formed by the temperature sensing probe, the bearing body, and the mounting hole is filled with thermally conductive filler.

[0013] In one possible implementation, the mounting monitoring base has grooves at both ends, and the bearing body is mounted in the grooves by an interference fit between its outer ring and the grooves.

[0014] In one possible implementation, a base plate is fixedly installed on both sides of the bottom of the mounting monitoring base, and several symmetrically arranged mounting slots are opened on it.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] In this monitoring mechanism, the structure used for temperature monitoring adopts a modular design, consisting of a thermal imaging monitoring frame and a contact temperature sensing component. Both of these components are highly integrated and are connected to the monitoring mounting base. When damage occurs or maintenance is required, the thermal imaging monitoring frame and the contact temperature sensing component can be removed as a whole by removing the fixing bolts, which significantly reduces the difficulty of maintenance and makes the entire monitoring mechanism have a relatively simple structure and low operating costs.

[0017] In addition, since the thermal imaging monitoring frame can perform thermal imaging monitoring of the bearing body, while the contact temperature sensing component performs fixed-point temperature measurement on the outer ring of the bearing body, a scheme of multiple measures working together to monitor temperature can be formed, making the monitoring results more accurate and reliable. Furthermore, when one part is damaged, the detection results of the thermal imaging monitoring frame and the contact temperature sensing component will differ significantly, which can remind staff to carry out timely maintenance of the entire monitoring mechanism, thus having a self-inspection effect.

Detailed Implementation

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1 - Figure 2 As shown, this embodiment provides a self-aligning roller bearing working thermal effect monitoring mechanism, including a monitoring mounting base 1, with bearing bodies 2 embedded at both ends. The monitoring mounting base 1 has a monitoring cavity 11, and both sides of the monitoring mounting base 1 have mounting ports 12 communicating with the monitoring cavity 11. Mounting holes 13 corresponding to the positions of the bearing bodies 2 are located on both sides of the mounting ports 12; a thermal imaging monitoring frame 3, which is inserted into the mounting port 12, and its working end extends into the monitoring cavity 11 facing the bearing body 2; and a contact-type temperature sensing component 4, which is inserted into the mounting hole 13, and its working end is in contact with the outer ring of the bearing body 2.

[0027] Based on the above structural scheme, the structure used for temperature monitoring adopts a modular design, consisting of a thermal imaging monitoring frame 3 and a contact-type temperature sensing component 4. Both of these components have strong integration and are plugged into the monitoring mounting base 1. Specifically, the thermal imaging monitoring frame 3 is plugged into the mounting port 12, and the contact-type temperature sensing component 4 is plugged into the mounting hole 13. Both are fixedly connected to the monitoring mounting base 1 by bolts. When damage occurs or maintenance is required, the thermal imaging monitoring frame 3 and the contact-type temperature sensing component 4 can be removed as a whole by removing the fixing bolts, which significantly reduces the maintenance difficulty and makes the entire monitoring mechanism have a relatively simple structure and low operating cost.

[0028] In addition, the thermal imaging monitoring frame 3 can perform thermal imaging monitoring of the bearing body 2, while the contact temperature sensing component 4 performs fixed-point temperature measurement on the outer ring of the bearing body 2. This constitutes a scheme of multiple measures working together to monitor the temperature, making the monitoring results more accurate and reliable. Furthermore, when a certain part is damaged, the detection results of the thermal imaging monitoring frame 3 and the contact temperature sensing component 4 will show significant differences, which can remind the staff to carry out timely maintenance of the entire monitoring mechanism, thus having a self-inspection effect.

[0029] In the above scheme, such as Figure 3 - Figure 4As shown, the thermal imaging monitoring frame 3 includes a mounting cover plate 31, on the inner end face of which symmetrically arranged support rods 32 are fixedly installed. A snap-fit ​​mounting bracket 33 is fixedly connected to the front end of the support rods 32, wherein symmetrically arranged thermal imaging probes 34 are snap-fitted onto it. Both ends of the snap-fit ​​mounting bracket 33 have mounting slots 331, the size of which matches the outer size of the thermal imaging probes 34. The snap-fit ​​mounting bracket 33 is entirely made of elastic material. Based on the above structural scheme, when the mounting cover plate 31 and the mounting monitoring base 1 are fixed... After the connection is established, the thermal imaging probe 34, which is snapped into the snap-fit ​​mounting bracket 33, will be fixed in the monitoring cavity 11, thereby enabling real-time monitoring of the bearing body 2 in its working state to monitor its thermal effect. The mounting cover plate 31 and the snap-fit ​​mounting bracket 33 are provided with a set of wire grooves 37. The cable of the thermal imaging probe 34 is arranged along the wire grooves 37. The wire grooves 37 provide the necessary structural foundation for the cable of the thermal imaging probe 34 to be led out, ensuring that the thermal imaging probe 34 can transmit information.

[0030] like Figure 3 - Figure 5 As shown, a plug-in frame 35 matching the size of the mounting opening 12 is fixedly provided on the inner end face of the mounting cover 31, and a connecting shaft 36 is fixedly provided at each of the four corners of the inner end face of the mounting cover 31. A positioning slot 121 surrounding the mounting opening 12 is provided on the outer side of the mounting monitoring seat 1, the size of which matches the size of the mounting cover 31, and a positioning groove 122 corresponding to the connecting shaft 36 is provided at each of the four corners of the positioning slot 121. In the above structural scheme, the snap-fit ​​between the plug-in frame 35 and the mounting opening 12 can play a role in positioning and support, making the fixing of the mounting cover 31 more stable and less prone to shaking. In addition, the snap-fit ​​between the positioning slot 121 and the mounting cover 31, and the snap-fit ​​between the positioning groove 122 and the connecting shaft 36 can further enhance the stability of the mounting cover 31 after installation, and can play a guiding and positioning role during the installation process of the mounting cover 31.

[0031] In the above scheme, such as Figure 3 As shown, the contact-type temperature sensing component 4 includes a closed cover 41, on the inner end face of which a temperature sensing probe 42 is fixedly disposed. The end of the temperature sensing probe 42 is in contact with the outer ring of the bearing body 2. The gap formed by the temperature sensing probe 42, the bearing body 2, and the mounting hole 13 is filled with a thermally conductive filler 43. The temperature sensing probe 42, which is in contact with the outer ring of the bearing body 2, can monitor the temperature of the outer ring of the bearing body 2 in real time and transmit the temperature signal. The thermally conductive filler 43 can increase the contact area between the temperature sensing probe 42 and the outer ring of the bearing body 2, thereby improving the effect and accuracy of its temperature monitoring.

[0032] For the installation of monitoring base 1, such as Figure 2 , Figure 5As shown, the monitoring base 1 has grooves 14 at both ends. The bearing body 2 is installed in the grooves 14 by interference fit between its outer ring and the grooves 14. The above structure provides the necessary structural foundation for the fixed installation of the bearing body 2. In addition, the bottom of both sides of the monitoring base 1 is fixedly provided with a base plate 15, which has several symmetrically arranged mounting slots 16. This structure provides the necessary structural foundation for the fixed installation of the monitoring base 1 as a whole. It can be installed on the existing structure and perform thermal effect detection on the bearing body 2 in the working state without affecting the rotation of the drive shaft.

[0033] The working principle and usage process of this utility model:

[0034] The thermal imaging monitoring frame 3 is installed in the mounting port 12, and the contact temperature sensing component 4 is installed in the mounting hole 13. Both are fixedly connected to the monitoring base 1 by bolts. When damage occurs or maintenance is required, the thermal imaging monitoring frame 3 and the contact temperature sensing component 4 can be removed as a whole by removing the fixing bolts, which significantly reduces the maintenance difficulty. At the same time, the entire monitoring mechanism has a relatively simple structure and low operating cost. When installing the thermal imaging monitoring frame 3 and the contact temperature sensing component 4, the disassembly steps are reversed.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
