Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a bearing with lubrication monitoring function. Background Technology

[0002] Bearings are a crucial component in modern mechanical equipment. Their main function is to support rotating mechanical parts and reduce the coefficient of friction of mechanical loads during transmission. In other words, bearings are components that fix and reduce the coefficient of friction of loads during mechanical transmission.

[0003] When bearings are in use, lubricating oil is usually applied to them to lubricate them. However, it is difficult to accurately control the lubrication status. During the use of lubricating oil, factors such as oil level, temperature, and quality will affect the lubrication effect. In order to monitor the lubrication status of bearings in real time, thereby improving the operational reliability of equipment and extending its service life, we have designed a bearing with lubrication monitoring function. Utility Model Content

[0004] The purpose of this invention is to provide a bearing with lubrication monitoring function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bearing with lubrication monitoring function includes a bearing body mounted on a rotating shaft. The bearing body has an external bearing mounting seat. The bearing mounting seat has two cavities for lubricating oil flow, symmetrically distributed on the left and right sides of the bearing body. An oil inlet is located on the upper part of the left side surface of the bearing mounting seat, and an oil outlet is located on the lower part of the left side surface. The inner end of the oil inlet extends to the top of the right-side cavity and communicates with its interior. The inner end of the oil outlet extends to the bottom of the left-side cavity and communicates with its interior. A first oil supply pipe is connected to the outer end of the oil inlet, and the other end of the first oil supply pipe extends to the bottom of an oil reservoir. A first pump body is mounted on the first oil supply pipe. A second oil supply pipe is connected to the outer end of the oil outlet, and the other end of the second oil supply pipe extends to the top of the oil reservoir and is detachably connected to a filter cover. A second pump body is mounted on the second oil supply pipe. A temperature detector is located at the bottom of the side wall of the left-side cavity, and an oil level detector is located at the lower part of the side wall of the right-side cavity. A vibration detector is located inside the bearing mounting seat.

[0007] As a preferred embodiment of this utility model: an oil quality detector is provided on the inner surface of the filter cover, and the oil quality detector is located inside the second oil delivery pipe.

[0008] As a further preferred embodiment of this utility model: the filter screen cover is threadedly fitted onto the opening of the second oil pipeline, and the top of the oil storage tank is movably provided with a tank cover.

[0009] As a further preferred embodiment of this utility model, the cavity is connected to the interior of the bearing body.

[0010] As a further preferred embodiment of this utility model: the vibration detector is in contact with the outer surface of the outer ring of the bearing body.

[0011] The beneficial effects of this utility model are as follows: During use, the first pump body draws lubricating oil from the oil tank and delivers it to the cavity through the first oil supply pipe and oil inlet. The lubricating oil then enters the bearing body, providing lubrication. As the bearing body operates, the state of the lubricating oil changes. When the temperature reaches the warning set value, the temperature detector monitors it in real time and provides real-time information to maintenance personnel via a display or data interface. When there is excessive lubricating oil inside the bearing body, as the oil level rises, the oil level detector detects an excess, indicating that lubricating oil is excessive, thus reminding maintenance personnel not to add more oil or to add more. To drain excess lubricating oil, the second pump pumps it back into the reservoir. Over time, some used lubricating oil accumulates in the second oil supply pipe. When the drained oil returns to the reservoir, it first passes through a filter screen to intercept contaminants, ensuring effective lubrication. Simultaneously, an oil quality detector on the inner surface of the filter screen measures the oil's pH value, preventing quality degradation and ensuring optimal lubrication. As the bearing rotates, a vibration detector monitors its operating status based on mechanical vibrations, indirectly assessing lubrication conditions. In summary, this device enables multi-parameter lubrication monitoring, ensuring bearing reliability and extending its lifespan, making it worthy of widespread adoption. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] Please see Figure 1-2 In this embodiment of the present invention, a bearing with lubrication monitoring function includes a bearing body 12 mounted on a rotating shaft 1. A bearing mounting seat 2 is provided on the outside of the bearing body 12. Two cavities 5 are provided inside the bearing mounting seat 2 for lubricating oil flow, symmetrically distributed on the left and right sides of the bearing body 12. The cavities 5 communicate with the interior of the bearing body 12. An oil inlet hole 4 is provided on the upper part of the left side surface of the bearing mounting seat 2, and an oil outlet hole 11 is provided on the lower part of the left side surface of the bearing mounting seat 2. The inner end of the oil inlet hole 4 extends to the top of the cavity 5 on the right side and communicates with the interior of the cavity 5. The inner end of the oil outlet hole 11 extends to the cavity 5 on the left side. The bottom is connected to the inside of the cavity 5. The outer end of the oil inlet 4 is connected to the first oil supply pipe 7. The other end of the first oil supply pipe 7 extends to the bottom of the oil storage tank 16. The first oil supply pipe 7 is equipped with a first pump body 6. The outer end of the oil outlet 11 is connected to the second oil supply pipe 9. The other end of the second oil supply pipe 9 extends to the top of the oil storage tank 16 and is detachably connected to a filter screen cover 14. The second oil supply pipe 9 is equipped with a second pump body 8. The bottom of the side wall of the cavity 5 on the left side is equipped with a temperature detector 10. The lower part of the side wall of the cavity 5 on the right side is equipped with an oil level detector 13. The bearing mounting seat 2 is equipped with a vibration detector 3. The vibration detector 3 is in contact with the outer surface of the outer ring of the bearing body 12.

[0018] An oil quality detector 15 is provided on the inner surface of the filter cover 14. The oil quality detector 15 is located inside the second oil supply pipe 9. The oil quality detector 15 is used to detect the acid and alkalinity of the lubricating oil. The detection of the acid and alkalinity of the lubricating oil is of great significance for ensuring the safe operation of mechanical equipment and extending the service life of the equipment. By regularly detecting the acid and alkalinity of the lubricating oil, the use of lubricating oil can be optimized, equipment maintenance costs can be reduced, and production efficiency can be improved.

[0019] The filter screen cover 14 is threaded onto the opening of the second oil supply pipe 9, and the top of the oil storage tank 16 is movably covered with a cover; opening the cover makes it easy to add lubricating oil into the oil storage tank 16, and also makes it easy for staff to remove the filter screen cover 14 for cleaning.

[0020] Specifically, during use, the device draws lubricating oil from the oil reservoir 16 via the first pump body 6 and delivers it to the cavity 5 through the first oil supply pipe 7 and the oil inlet 4. The lubricating oil then enters the bearing body 12 to provide lubrication. As the bearing body 12 operates, the state of the lubricating oil changes. When the temperature reaches the warning set value, the temperature detector 10 monitors it in real time and provides real-time information to maintenance personnel via a display or data interface. When there is excessive lubricating oil inside the bearing body 12, the oil level rises. When the oil level detector 13 detects the oil level, it indicates that there is excessive lubricating oil, thus reminding maintenance personnel not to add more oil or to drain the oil. Excess lubricating oil can be pumped back to the oil storage tank 16 via the second pump body 8. Over time, some used lubricating oil will accumulate in the second oil delivery pipe 9. When the pumped-out lubricating oil returns to the oil storage tank 16, it first passes through the filter cover 14, which intercepts and filters contaminants in the lubricating oil to ensure subsequent lubrication. Simultaneously, the oil quality detector 15 located on the inner surface of the filter cover 14 can detect the pH value of the lubricating oil, preventing a decline in lubricating oil quality and affecting lubrication performance. As the bearing body 12 rotates, the vibration detector 3 can detect the working state of the bearing body 12 based on mechanical vibration, thereby indirectly judging the lubrication condition. In summary, this device can achieve multi-parameter lubrication detection, fully ensuring the reliability of bearing operation and extending its service life, making it worthy of widespread application.
