[0022] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned direction words are not used to limit the present invention.

[0023] See also Figure 1-4 , the utility model provides the following technical solutions:

[0024] A multi-point lubrication bearing seat includes a base 1, an upper cover 2 is covered on the base 1, two bearings 5 ​​are clamped between the base 1 and the upper cover 2, a clamping sleeve 3 is connected to the inner side of the bearing 5, and the two clamping sleeves 3 jointly fix the rotating shaft 9 to form the main body of the bearing seat;

[0025] The base 1 and the two end covers of the upper cover 2 are both connected with a separator ring 4, which extends from the side into the bearing 5. A filling port 7 is provided on the top of the upper cover 2, and two guide pipes 6 are connected to the filling port 7. The guide pipes 6 extend along the inner wall of the upper cover 2, and the other end of the guide pipes 6 is connected to the separator ring 4. A plurality of drip pipes 44 are provided on the separator ring 4, one end of the drip pipe 44 is connected to the guide pipe 6, and the other end of the drip pipe 44 extends into the bearing 5. When adding lubricating oil, the oil can directly enter the interior of the bearing 5 through the drip pipe 44, thereby reducing oil overflow, ensuring the filling amount of lubricating oil, and ensuring the cleanliness of the environment.

[0026] The bearing 5 includes an outer ring 51, an inner ring 52 and a retaining frame 53. An extension column 41 is provided on the side of the liquid separator ring 4 facing the bearing 5. The extension column 41 extends into the interior of the bearing 5 from the gap between the outer ring 51 and the inner ring 52. The drip tube 44 passes through the extension column 41, that is, the drip tube 44 is arranged inside the bearing 5 away from the opening of the guide tube 6.

[0027] The retaining frame 53 may rotate during the rotation of the bearing 5 , and the extension column 41 is spaced apart from the retaining frame 53 , thereby avoiding interference of the liquid separator ring 4 on the operation of the bearing 5 .

[0028] A liquid storage tank 42 is provided in the liquid separation ring 4. The liquid storage tank 42 is annular and is connected to a connecting pipe 43. The connecting pipe 43 is connected to the guide pipe 6. A sealing ring 8 is provided on the opening of the guide pipe 6 away from the filling port 7. The sealing ring 8 is sealed with the liquid separation ring 4 to prevent the oil from overflowing from the connection. Several dripping pipes 44 are all connected to the liquid storage tank 42. The oil enters the liquid storage tank 42 through the guide pipe 6 and is then distributed to the dripping pipes 44, so that the oil distribution at each point is as even as possible, which promotes the balance of the filling amount at each point and improves the lubrication effect.

[0029] The clamping sleeve 3 includes a sleeve body 31, which abuts against the inner wall of the inner ring 52. An outer ring 32 and an inner ring 33 are provided at both ends of the sleeve body 31. The outer ring 32 and the inner ring 33 abut against the two side walls of the inner ring 52 respectively. The outer ring 32 is provided on the side of the bearing 5 facing the outside of the bearing seat. The maximum diameter of the outer ring 32 is greater than the maximum diameter of the inner ring 52, that is, the inner ring 52 is sealed in the outer ring 32. When the added lubricating oil drips on the outer wall of the inner ring 52, it will not overflow to the outside of the bearing seat due to the blocking of the outer ring 32, thereby ensuring the amount of lubricating oil added and maintaining the cleanliness of the external working environment.

[0030] One side of the inner ring 33 is connected to the outer wall of the inner ring 52, and the other side of the inner ring 33 extends toward the axis of the clamping sleeve 3, that is, the ring wall where the inner ring 33 and the inner ring 52 meet is inclined toward the axis.

[0031] A snap ring 11 is provided on the end cover of the base 1, and a snap ring 21 is provided on the end cover of the upper cover 2. Both the snap ring 11 and the snap ring 21 are concave in shape, and the outer ring 51 is snapped into the concave groove. The two sides of the concave shape abut against the two side surfaces of the outer ring 51. The inner ring of the side of the snap ring 11 on the inner side of the bearing seat is in an inclined shape with one end connected to the inner wall of the outer ring 51 and the other end extending downward.

[0032] The oil filled in the bearing 5 is blocked by the outer ring 32 and will not overflow to the outside of the bearing seat, and the inclined surfaces of the inner ring 33 and the snap ring 11 have a guiding effect on the oil passing through here. Excessive lubricating oil will slide along the inclined parts of the inner ring 33 and the snap ring 11 to the inside of the bearing seat, avoiding oil overflow while avoiding excessive lubrication and preventing damage to the bearing 5.

[0033] Specifically, a separator ring 44 is provided on the side of the bearing 5, and an extension column 41 is provided on the separator ring. The extension column 41 extends from between the outer ring 51 and the inner ring 52 into the interior of the bearing 5. The separator ring 4 is connected to a plurality of dripping tubes 44, which pass through the extension column 41. The openings of the dripping tubes 44 are provided inside the bearing 5. The separator ring 44 is connected to the guide pipe 6 of the upper cover 2. The lubricating oil enters the separator ring 4 through the guide pipe 6 and is then dispersed into the interior of the bearing 5 through the plurality of dripping tubes 44 on the separator ring 4. Through multi-point lubrication, the lubricating oil is directly added to the interior of the bearing 5, thereby improving the lubrication performance.

[0034] The side of the clamping sleeve 3 facing the outside of the bearing seat is the outer ring 32. The maximum diameter of the outer ring 32 is greater than the maximum diameter of the inner ring 52 of the bearing 5, that is, the inner ring 52 is sealed in the outer ring 32. The lubricating oil entering the interior of the bearing 5 will not overflow from the clamping sleeve 3, thereby ensuring the cleanliness of the external working environment.
