Description

Technical Field

[0001] The present invention relates to the technical field of bearing seats, and particularly to a dust-proof bearing seat for mining machinery. Background Art

[0002] A bearing seat is a mechanical component used to support and install bearings. It is usually installed in a mechanical structure to provide support and positioning for the bearings. The design of the bearing seat can have many forms, depending on specific applications and requirements. A bearing seat with a dust-proof function is usually designed for industrial and mechanical applications to prevent dust, particulate matter, and other contaminants from entering the bearing system, thereby extending the service life of the bearings and improving the reliability of the equipment.

[0003] For example, patent (CN221120685U) discloses a dust-proof bearing seat for mining machinery, which includes a limiting component. Using an embedded sliding structure, it can perform circumferential sliding, drive other components without affecting normal installation and use. Specifically: the limiting component includes a seat body, a chute is opened inside the seat body, a slider is slidably connected in the chute, and a groove is opened at the bottom of the inner wall of the seat body; a cleaning component, when the limiting component slides, it will drive the cleaning component to remove dust, and the cleaning component can slide into the limiting component. It can effectively clean the dust inside the seat body without generating a lot of dust accumulation, achieving a dust-proof effect. The slide plate can be retracted into the seat body and fixed by a clamping plate after use, that is, when the slide plate is not in use, it will become a part of the interior of the seat body and will not affect the normal use of the seat body.

[0004] When using the above technology, it is found that the following technical problems exist in the prior art: In the prior art, the working environment of mining machinery is harsh, with a large amount of dust and high temperature, and the bearing seat is prone to dust ingress. The above prior art is used to clean the dust inside the bearing, and at this time, not much dust will be generated. However, it is not easy to adopt because, due to the large dust particles, when they enter the bearing, leaving aside whether they can be effectively cleaned, the dust particles will cause damage to the bearing, resulting in increased bearing wear and shortened service life. At the same time, when the dust particles rotate with the bearing, it will cause the bearing to overheat, and it will also affect the lubrication effect of the bearing, further exacerbating the wear of the bearing. Therefore, it is necessary to directly prevent dust from entering the bearing interior. Moreover, the existing bearing seats have poor dust-proof and heat-dissipation effects, and are not easy to disassemble and repair, making it difficult to meet the usage requirements of mining machinery. For this reason, we designed a dust-proof bearing seat for mining machinery to provide another technical solution to the above technical problems. Summary of the Invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] As described in the background art, in the prior art, the working environment of mining machinery is harsh, with a large amount of dust and high temperature. The bearing seat is prone to dust ingress. In the above prior art, the dust inside the bearing is cleaned, and at this time, not much dust will be generated. However, it is not easy to adopt because, due to the large dust particles, when they enter the bearing, leaving aside whether they can be effectively cleaned, the dust particles will cause damage to the bearing, resulting in increased bearing wear and shortened service life. At the same time, when the dust particles rotate with the bearing, it will cause the bearing to heat up, which will also affect the lubrication effect of the bearing and further exacerbate the wear of the bearing. Therefore, dust is directly prevented from entering the bearing interior. Moreover, the existing bearing seats have poor dust prevention and heat dissipation effects, and are not easy to disassemble and repair, making it difficult to meet the usage requirements of mining machinery.

[0023] To solve this technical problem, the present invention provides a dust-proof bearing seat for mining machinery.

The snap ring block 11 is in sealed sliding connection between the outer seal ring 13 and the inner seal ring 17. Dust-proof mechanisms for protecting against dust are provided at both ends of the bearing support one 1 and the bearing support two 2 that are away from each other. A number of rotating shafts 18 are rotatably connected inside the bearing support one 1 and the bearing support two 2. Bearings are rotatably connected to the inner sides of the number of rotating shafts 18. A connection mechanism for disassembly and repair is provided between both sides of the bearing support one 1 and the bearing support two 2.

[0025] A dust-proof bearing seat for mining machinery provided by the present invention assembles the bearing between the bearing support one 1 and the bearing support two 2, and then places the device in a mine for use. In order to prevent dust in the mine from entering the inner side of the bearing, the bearing support one 1 drives the snap ring block 11 to be in sliding connection between the outer seal ring 13 and the inner seal ring 17. At this time, the connection mechanism drives the bearing support one 1 and the bearing support two 2 to be assembled and combined, so as to effectively disassemble and repair the bearing. Dust-proof mechanisms are assembled at both ends of the bearing support one 1 and the bearing support two 2 that are away from each other, so as to protect the bearing between the bearing support one 1 and the bearing support two 2.

An outer sealing ring 13 and an inner sealing ring 17 are fixed at one end of the second bearing support 2 close to the first bearing support 1. The snap ring block 11 is in sealing sliding connection between the outer sealing ring 13 and the inner sealing ring 17. A sealing ring is assembled between the outer sealing ring 13 and the inner sealing ring 17, and the sealing ring is in sealing sliding connection with the snap ring block 11. Dust-proof mechanisms for protecting against dust are provided at the ends of the first bearing support 1 and the second bearing support 2 that are away from each other. A number of rotating shafts 18 are rotatably connected inside the first bearing support 1 and the second bearing support 2. A bearing is rotatably connected inside the number of rotating shafts 18. A connection mechanism for disassembly and maintenance is provided between the two sides of the first bearing support 1 and the second bearing support 2; During use, the bearing is assembled between the first bearing support 1 and the second bearing support 2, and then the device is placed in a mine for operation. To prevent dust in the mine from entering the inside of the bearing, the first bearing support 1 drives the snap ring block 11 to be in sliding connection between the outer sealing ring 13 and the inner sealing ring 17. At this time, the connection mechanism drives the first bearing support 1 and the second bearing support 2 to be assembled and combined, so as to effectively disassemble and repair the bearing. Dust-proof mechanisms are assembled at the ends of the first bearing support 1 and the second bearing support 2 that are away from each other, so as to protect the bearing between the first bearing support 1 and the second bearing support 2; The dust-proof mechanism includes a threaded ring 9, a sealing disc 8, a dust-proof cover 3, a clamping block 16 and a limiting component. Threaded rings 9 are fixed at the ends of the first bearing support 1 and the second bearing support 2 that are away from each other. A dust-proof cover 3 is threadedly connected to the outside of the threaded ring 9. The inside of the dust-proof cover 3 is in sealing rotation connection with the bearing. Clamping blocks 16 are fixed at the ends of the first bearing support 1 and the second bearing support 2 that are away from each other and inside the threaded ring 9. A sealing disc 8 is slidably connected to the outside of the clamping block 16. The inside of the sealing disc 8 is in sealing rotation connection with the bearing. One end inside the dust-proof cover 3 is in sliding connection with the sealing disc 8; Specifically, the dust-proof cover 3 is threadedly connected to the threaded ring 9, and the dust-proof cover 3 effectively protects the rotating connection between the bearing and the first bearing support 1 and the second bearing support 2, thereby preventing external dust from entering the gap between the bearing and the first bearing support 1 and the second bearing support 2. At this time, the sealing disc 8 is clamped with the clamping block 16, further preventing external dust from entering the bearing interior. Therefore, the dust-proof cover 3 and the sealing disc 8 effectively prevent dust from entering the gap between the first bearing support 1 and the second bearing support 2 and the bearing rotation, so as to effectively prevent outside dust from entering the bearing interior, thus increasing the service life of the bearing; The limiting component includes a limiting block 19, a fixing piece 20, a pin 22, a U-shaped block 23, a slide bar 24 and a spring 25. On one side of the mutually distant ends of the first bearing support 1 and the second bearing support 2, a limiting block 19 and a fixing piece 20 are fixed respectively. The inner side of the limiting block 19 is slidably connected with a pin 22. One end of the pin 22 is clamped with the dust cover 3. A number of limiting holes 21 are formed on the outer side of the dust cover 3. One end of the pin 22 is slidably connected with the corresponding limiting hole 21; The inner side of the pin 22 is slidably connected with a slide bar 24. The end of the slide bar 24 away from the pin 22 is fixed to the fixing piece 20. The inner side of the pin 22 is slidably connected with a spring 25. One end of the limiting block 19 is fixed with a U-shaped block 23. The inner side of the U-shaped block 23 is slidably connected with the pin 22; Further, the dust cover 3 is threadedly connected with the sealing disc 8. At this time, the dust cover 3 effectively cuts off the dust outside the bearing seat. At this time, to prevent the slight vibration generated when the bearing rotates at high speed from causing the dust cover 3 and the sealing disc 8 to become loose. At this time, the spring 25 drives the pin 22 to be clamped into the corresponding limiting hole 21 inside the dust cover 3, so as to improve the stability of the dust cover 3. When the dust cover 3 needs to be disassembled, at this time, the pin 22 is pulled to be clamped with the U-shaped block 23. Then the pin 22 is disengaged from the limiting hole 21. Thus, the dust cover 3 is rotated to be disengaged from the sealing disc 8, and then the sealing disc 8 and the dust cover 3 can be replaced and repaired; The connecting mechanism includes a connecting seat 4, a clamping seat 5, a linkage rod 6 and a nut 7. Connecting seats 4 are fixed on both sides of the first bearing support 1. Clamping seats 5 are fixed on both sides of the second bearing support 2. The inner side of the connecting seat 4 is rotatably connected with a linkage rod 6. One end of the linkage rod 6 is slidably connected with the clamping seat 5. One end of the linkage rod 6 is threadedly connected with a nut 7. One end of the nut 7 is slidably connected with the clamping seat 5; Specifically, when the bearing needs to be assembled, at this time, the bearing is placed inside the first bearing support 1 and the second bearing support 2. Then the bearing rotates with the rotating shaft 18. At this time, the first bearing support 1 drives the snap ring block 11 to be slidably connected between the outer sealing ring 13, the inner sealing ring 17 and the second bearing support 2. At this time, the linkage rod 6 is rotated to be slidably connected with the clamping seat 5. Then the nut 7 is rotated by a tool to apply pressure to the clamping seat 5 and the second bearing support 2, which is convenient for increasing the connection effect between the first bearing support 1 and the second bearing support 2, so as to facilitate the disassembly of the device, and effectively replace and repair the bearing, improving the maintenance efficiency.

[0030] Embodiment 2 Please refer to Figures 5 - 8, a dust-proof bearing seat for mining machinery. A heat dissipation mechanism for cooling the bearing is arranged between the bearing support one 1 and the bearing support two 2. The heat dissipation mechanism includes an exhaust hood 10 and an exhaust fan 12. The exhaust fan 12 is fixed between the bearing support one 1 and the bearing support two 2 on the outer side of the bearing. A plurality of heat exhaust holes 15 are opened at the top and bottom inside the snap ring block 11. The exhaust hoods 10 are fixed at the top and bottom of the snap ring block 11. A plurality of exhaust holes 14 are fixed on one side inside the exhaust hood 10; Specifically, when the bearing rotates for a long time, the bearing rotates and rubs against the rotating shaft 18, the bearing support one 1 and the bearing support two 2, generating a certain amount of heat. The heat accumulates between the bearing support one 1 and the bearing support two 2, reducing the service life of the bearing. Then, the exhaust fan 12 is driven to rotate by the rotating bearing, so that the exhaust fan 12 discharges the heat generated between the bearing support one 1 and the bearing support two 2. The heat will enter the inside of the exhaust hood 10 through the heat exhaust holes 15 and finally be discharged through the exhaust holes 14, thus effectively reducing the working temperature of the bearing, improving the lubrication effect of the bearing, and further prolonging the service life of the bearing.

[0031] The use process of a dust-proof bearing seat for mining machinery provided by the present invention is as follows: When in use, the bearing is assembled between the bearing support one 1 and the bearing support two 2, and then the device is placed in a mine for operation. In order to prevent dust in the mine from entering the inner side of the bearing, the bearing support one 1 drives the snap ring block 11 to be slidably connected between the outer sealing ring 13 and the inner sealing ring 17. At this time, the rotating link 6 is slidably connected with the card seat 5, and then the nut 7 is rotated by a tool to press the card seat 5 and the bearing support two 2, facilitating to increase the connection effect between the bearing support one 1 and the bearing support two 2, so as to facilitate the disassembly of the device, and effectively replace and repair the bearing, improving the maintenance efficiency; Then, the dust-proof cover 3 is threadedly connected with the threaded ring 9. The dust-proof cover 3 effectively protects the rotating connection between the bearing, the bearing support one 1 and the bearing support two 2, preventing external dust from entering the gap between the bearing, the bearing support one 1 and the bearing support two 2. At this time, the sealing disc 8 is snap-connected with the block 16, further preventing external dust from entering the bearing interior. The dust-proof cover 3 effectively separates the dust outside the bearing seat. The spring 25 drives the bolt 22 to be snap-connected into the corresponding limiting hole 21 inside the dust-proof cover 3, thus preventing the dust-proof cover 3 from loosening under the vibration of the bearing during rotation; Finally, during the long-term operation of the bearing, the bearing rotates and rubs against the rotating shaft 18, the first bearing support 1, and the second bearing support 2, generating a certain amount of heat. The heat accumulates between the first bearing support 1 and the second bearing support 2, reducing the service life of the bearing. Then, the heat dissipation fan 12 is driven to rotate by the bearing, so that the heat dissipation fan 12 discharges the heat generated between the first bearing support 1 and the second bearing support 2. The heat enters the interior of the exhaust hood 10 through the heat dissipation holes 15 and is discharged through the exhaust holes 14, thereby effectively reducing the working temperature of the bearing, improving the lubrication effect of the bearing, and further extending the service life of the bearing.
