[0029] To make the purposes, technical solutions and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0030] Figure 1 A structure diagram of an online leveler support roller bearing seat in the online leveler support roller bearing seat oil leakage reconstruction method provided by the embodiment of the application.

[0031] In the prior art, online leveler support roller bearing seat oil discharge only relies on a hole punched in the bearing seat cover 7 oil level and connected to an exhaust fan to discharge oil, which not only pollutes the environment, but also causes poor oil discharge at the sealing place of the support roller close to the shaft side, resulting in running, leaking and dripping, further polluting the strip, and causing “spot” defects.

[0032] As Figures 1-3 In the application, the above problems are solved by increasing the oil discharge hole. Specifically, the application provides an online leveler support roller bearing seat oil leakage reconstruction method, which comprises the following steps:

[0033] S1: designing an oil discharge hole position on the online leveler support roller bearing seat to ensure that the oil level line of the oil discharge hole is at a first distance of the online leveler support roller bearing seat;

[0034] Specifically, the oil drain hole is used to drain the excess lubricating oil in the on-line leveler support roller bearing seat. Since the lubricating oil in the on-line leveler support roller bearing seat can play a role in lubricating the machine and parts, in order to ensure the normal operation of the on-line leveler support roller bearing seat, the lubricating oil in the on-line leveler support roller bearing seat cannot be too little and needs to maintain a certain content. On the other hand, if the lubricating oil is too much, it will also cause the machine to run smoothly, such as slipping, causing the machine to run failure, so the excess lubricating oil needs to be drained from the on-line leveler support roller bearing seat. That is, the height of the oil drain hole on the on-line leveler support roller bearing seat needs to be within a certain range, too high will cause the excess lubricating oil to be unable to drain in time and affect the normal operation of the machine, too low will also cause the on-line leveler support roller bearing seat to have not enough lubricating oil and affect the normal operation of the machine. After many observations and measurements, it is found that the first distance is 401.5-402.5mm, which is more appropriate, which can meet the position requirements of the above-mentioned oil drain hole. On the one hand, it can ensure that there is enough lubricating oil in the on-line leveler support roller bearing seat, and on the other hand, it can ensure that the excess lubricating oil in the on-line leveler support roller bearing seat is drained in time without affecting the normal operation of the machine.

[0035] S2: punch a first through hole at a second distance from the outer diameter of the bearing seat support 2 and parallel to the axis position;

[0036] Specifically, the first through hole is used to drain the excess lubricating oil in the bearing seat support 2. Since the lubricating oil in the bearing seat support 2 can play a role in lubricating the machine and parts, in order to ensure the normal operation of the bearing seat support 2, the lubricating oil in the bearing seat support 2 cannot be too little and needs to maintain a certain content. On the other hand, if the lubricating oil is too much, it will also cause the machine to run smoothly, such as slipping, causing the machine to run failure, so the excess lubricating oil needs to be drained from the bearing seat support 2. That is, the height of the oil drain hole on the bearing seat support 2 needs to be within a certain range, too high will cause the excess lubricating oil to be unable to drain in time and affect the normal operation of the machine, too low will also cause the bearing seat support 2 to have not enough lubricating oil and affect the normal operation of the machine. After many observations and measurements, it is found that the second distance is 1050mm, which is more appropriate, which can meet the position requirements of the above-mentioned oil drain hole. On the one hand, it can ensure that there is enough lubricating oil in the bearing seat support 2, and on the other hand, it can ensure that the excess lubricating oil in the bearing seat support 2 is drained in time without affecting the normal operation of the machine.

[0037] Further, through repeated observation and measurement, it is found that when the diameter of the first through hole is 20 mm, the first through hole can meet the position requirement of the oil drain hole. On the one hand, it can ensure that there is enough lubricating oil in the bearing seat support 2, and on the other hand, it can ensure that the excess lubricating oil in the bearing seat support 2 can be discharged in the shortest possible time without affecting the normal operation of the machine.

[0038] S3: punch a second through hole at a third distance from the outer diameter of the bearing seat end cover 3 and parallel to the axis position, and punch a G1 threaded interface outside the bearing seat end cover 3;

[0039] Specifically, the second through hole is used to drain excess lubricating oil in the bearing seat end cover 3. Since the lubricating oil in the bearing seat end cover 3 can play a role in lubricating the machine and parts, in order to ensure the normal operation of the bearing seat end cover 3, the lubricating oil in the bearing seat end cover 3 cannot be too little and needs to maintain a certain amount. On the other hand, if the lubricating oil is too much, it will also cause the machine to run smoothly, such as slipping, causing the machine to run out of trouble, so the excess lubricating oil needs to be drained from the bearing seat end cover 3. That is, the height of the oil drain hole on the bearing seat end cover 3 needs to be within a certain range. Too high will cause the excess lubricating oil to be discharged in time and affect the normal operation of the machine, and too low will also cause the bearing seat end cover 3 to have not enough lubricating oil and affect the normal operation of the machine. Through repeated observation and measurement, it is found that the third distance is 1040-1060 mm, which is more appropriate and can meet the position requirement of the oil drain hole. On the one hand, it can ensure that there is enough lubricating oil in the bearing seat end cover 3, and on the other hand, it can ensure that the excess lubricating oil in the bearing seat end cover 3 is discharged in time without affecting the normal operation of the machine.

[0040] Further, through repeated observation and measurement, it is found that the diameter of the second through hole is 20 mm, and the second through hole can meet the position requirement of the oil drain hole. On the one hand, it can ensure that there is enough lubricating oil in the bearing seat support 2, and on the other hand, it can ensure that the excess lubricating oil in the bearing seat support 2 can be discharged in the shortest possible time without affecting the normal operation of the machine.

[0041] S4: punch a third through hole at a fourth distance from the outer diameter of the bearing seat cover 6 and parallel to the axis position;

[0042] Specifically, the third through hole is used to discharge the excess lubricating oil in the bearing seat transparent cover 6. Since the lubricating oil in the bearing seat transparent cover 6 can play a role in lubricating the machine and parts, in order to ensure the normal operation of the bearing seat transparent cover 6, the lubricating oil in the bearing seat transparent cover 6 cannot be too little and needs to be kept at a certain content. On the other hand, if the lubricating oil is too much, it will also cause the machine to run smoothly, such as slipping, causing the machine to run failure, so the excess lubricating oil needs to be discharged from the bearing seat transparent cover 6. That is, the height of the oil discharge hole on the bearing seat transparent cover 6 needs to be within a certain range, too high will cause the excess lubricating oil to be discharged in time and affect the normal operation of the machine, too low will also cause the bearing seat transparent cover 6 to have not enough lubricating oil and affect the normal operation of the machine. After many observations and measurements, it is found that the fourth distance is 1040-1060mm, which is more appropriate, which can meet the above requirements of the position of the oil discharge hole. On the one hand, it can ensure that there is enough lubricating oil in the bearing seat transparent cover 6, and on the other hand, it can ensure that the excess lubricating oil in the bearing seat transparent cover 6 is discharged in time without affecting the normal operation of the machine.

[0043] Further, after many observations and measurements, it is found that the diameter of the third through hole is 20mm, and the third through hole can meet the above requirements of the position of the oil discharge hole. On the one hand, it can ensure that there is enough lubricating oil in the bearing seat transparent cover 6, and on the other hand, it can ensure that the excess lubricating oil in the bearing seat transparent cover 6 can be discharged in time within the shortest possible time without affecting the normal operation of the machine.

[0045] Specifically, the fourth through hole is used to discharge the excess lubricating oil in the deep groove ball bearing 4. Since the lubricating oil in the deep groove ball bearing 4 can play a role in lubricating the machine and parts, in order to ensure the normal operation of the deep groove ball bearing 4, the lubricating oil in the deep groove ball bearing 4 cannot be too little and needs to be kept at a certain content. On the other hand, if the lubricating oil is too much, it will also cause the machine to run smoothly, such as slipping, causing the machine to run failure, so the excess lubricating oil needs to be discharged from the deep groove ball bearing 4. That is, the height of the oil discharge hole on the deep groove ball bearing 4 needs to be within a certain range, too high will cause the excess lubricating oil to be discharged in time and affect the normal operation of the machine, too low will also cause the deep groove ball bearing 4 to have not enough lubricating oil and affect the normal operation of the machine. After many observations and measurements, it is found that the fourth through hole is set on the bearing seat support 2 and close to the deep groove ball bearing 4, which is more appropriate, which can meet the above requirements of the position of the oil discharge hole. On the one hand, it can ensure that there is enough lubricating oil in the deep groove ball bearing 4, and on the other hand, it can ensure that the excess lubricating oil in the deep groove ball bearing 4 is discharged in time without affecting the normal operation of the machine.

[0046] Further, through repeated observation and measurement, it is found that when the diameter of the fourth through hole is 15-17 mm, the fourth through hole can meet the position requirement of the oil drain hole. On the one hand, it can ensure that there is enough lubricating oil in the deep groove ball bearing 4, and on the other hand, it can ensure that the excess lubricating oil in the deep groove ball bearing 4 can be discharged in the shortest possible time without affecting the normal operation of the machine.

[0047] S6: Three fifth through holes are punched on the outer diameter of the thrust ring 5 near the bottom bearing seat support 2 position;

[0048] Specifically, the fifth through hole is used to drain excess lubricating oil in the thrust ring 5. Since the lubricating oil in the thrust ring 5 can play a role in lubricating the machine and parts, in order to ensure the normal operation of the thrust ring 5, the lubricating oil in the thrust ring 5 cannot be too little and needs to maintain a certain content. On the other hand, if the lubricating oil is too much, it will also cause the machine to run smoothly, such as slipping, causing the machine to run failure, so the excess lubricating oil needs to be drained from the thrust ring 5. That is, the height of the oil drain hole on the thrust ring 5 needs to be within a certain range, too high will cause the excess lubricating oil to be discharged in time and affect the normal operation of the machine, too low will also cause the thrust ring 5 to have not enough lubricating oil and affect the normal operation of the machine. Through repeated observation and measurement, it is found that when the fifth through hole is set on the outer diameter of the thrust ring 5 and near the bottom bearing seat support 2, it is more appropriate, which can meet the position requirement of the oil drain hole.
