Description

Technical Field

[0001] The utility model relates to the technical field of ball mill bearing seats, in particular to a medium and large-sized bearing seat system for a ball mill. Background Art

[0002] As an important equipment in grinding equipment, ball mill has a history of many years since its birth. It is widely used in metallurgy, medicine, chemical industry, ceramics, cement, construction, power and national defense industries. The load of a single medium and large bearing used in it can reach about 150 tons, and it needs to run continuously for 30 hours. Due to the high price of bearings, its installation and maintenance requirements are high to meet the high efficiency and long life of medium and large bearings.

[0003] Therefore, in practical applications, it is necessary to add grease to the bearing seat to ensure the normal operation of the bearing and reduce wear. However, the traditional bearing seat cannot automatically discharge the grease and needs to be manually disassembled and cleaned, which is time-consuming and labor-intensive. In addition, the grease and iron filings dropped by the worn bearing will re-enter the bearing, aggravating the wear of the bearing and affecting the service life of the bearing.

[0004] Therefore, we have designed a medium-to-large bearing seat system for ball mills, which can automatically realize the circulation filling and discharge of lubricating oil, and clean up the iron filings mixed in the lubricating oil, ensuring the cleanliness of the lubricating oil and not causing secondary wear to the bearings. The design is scientific and reasonable, and effectively improves the service life of the bearings. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0020] See also Figure 1-3 The present embodiment provides a medium-to-large-sized bearing seat system for a ball mill, including a bearing seat body 1, a bearing mounting hole 2 is provided on the bearing seat body 1, a sealing end cover 3 is provided on the rear side of the bearing mounting hole 2, an oil inlet 5 communicating with the bearing mounting hole 2 is provided on the sealing end cover 3, a bearing seat oil chamber 6 is provided at the bottom of the bearing seat body 1, and an oil circulation hole 7 communicating with the bearing seat oil chamber 6 is provided at the bottom of the bearing mounting hole 2. Preferably, three oil circulation holes 7 are evenly arranged, and the oil level in the bearing seat oil chamber 6 is higher than the top surface of the steel column at the bottom of the bearing in the bearing mounting hole 2, so that the lubricating oil can carry the temperature of the bearing and the wear iron filings, and an iron remover 9 is provided in the bearing seat oil chamber 6. The iron remover 9 is preferably a permanent magnetic iron remover, which is used to absorb the iron filings mixed in the oil to purify the oil and prevent the wear iron filings from flowing back into the bearing with the random oil.

[0021] In order to realize the circulation of lubricating oil, the oil inlet 5 and the bearing seat oil chamber 6 are connected through an oil circulation cooling component located outside the bearing seat body 1. Specifically, the oil circulation cooling component includes an oil pump 10 and an air-cooled oil tank 11. The bearing seat body 1 is provided with an oil return port 8 which is connected to the bearing seat oil chamber 6. The oil return port 8 is connected to the oil inlet end of the air-cooled oil tank 11 through an oil outlet pipe 14. The oil outlet end of the air-cooled oil tank 11 is connected to the oil inlet 5 through an oil inlet pipe 13. The oil pump 10 is arranged on the oil inlet pipe 13.

[0022] In addition, after the bearing is installed, in order to better monitor the temperature of the bearing in the bearing mounting hole 2, a temperature sensor 4 located in the bearing mounting hole 2 is provided on the sealing end cover 3. In actual application, the temperature sensor 4 can be in contact with the outer ring end of the bearing.

[0023] In order to ensure the sealing performance of the bearing mounting hole 2, a shaft sealing ring 12 is provided on the front side of the inner wall of the bearing mounting hole 2, which contacts the main shaft of the ball mill, ensuring the sealing performance of the bearing mounting hole 2 and avoiding oil leakage.

[0024] It should be noted that in actual applications, as a routine operation familiar to technical personnel in this field, in order to realize the maintenance of the bearing seat oil chamber 6, a sealed inspection door for inspecting the bearing seat oil chamber 6 should be provided on the bearing seat body 1 to facilitate the inspection and cleaning of the iron remover 9. This is a routine operation and will not be repeated here.

[0025] It should be further explained that the temperature sensor, iron remover 9, oil pump 10 and air-cooled oil tank 11 are all conventional general structures familiar to technical personnel in this field. Their models can be customized and purchased or processed according to needs, and this application will not go into details.

[0026] It should be noted that, in actual applications, the model of the bearing seat is selected according to the matching bearing model, such as 24084, 23080, 53868, 23172, 23092 and other different models, which are common knowledge familiar to technicians in this field and will not be repeated here.

[0027] In practical applications, such as Figure 1 As shown, after the bearing is installed in the bearing mounting hole 2, the temperature sensor 4 contacts the outer ring end of the bearing to sense the temperature of the bearing in real time. When the bearing needs to be cooled, the oil pump 10 is started to allow the lubricating oil in the air-cooled oil tank 11 to enter the bearing mounting hole 2 along the oil inlet pipe 13 through the oil inlet port 5. After soaking the bearing, the iron filings that fall off the bearing due to wear and tear are carried into the bearing seat oil chamber 6 through the oil circulation hole 7 along with the oil. The iron filings are adsorbed onto the iron remover 9, and the oil returns to the air-cooled oil tank 11 through the oil return port 8 and the oil outlet pipe 14, thereby realizing the circulation of the lubricating oil and achieving the lubrication, cooling and cleaning of the bearing.

[0028] It should be noted that, as a conventional design familiar to technical personnel in this field, in order to achieve comprehensive regulation of the temperature sensor 4, the oil pump 10 and the air-cooled oil tank 11, a main controller electrically connected to the temperature sensor 4, the oil pump 10 and the air-cooled oil tank 11 should be provided outside the bearing seat. The main controller can be obtained through customized purchase, so that when the temperature sensor 4 detects that the bearing temperature reaches the specified temperature to be cooled, the oil pump 10 and the air-cooled oil tank 11 can work in time to achieve cooling of the bearing.

[0029] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application. For those skilled in the art, solutions or features that belong to the prior art or common knowledge are not described in detail in the above embodiments.

[0030] In addition, the technical solutions of the present application are not limited to the above-mentioned embodiments. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
