DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, the bearing with good lubrication effect comprises a bearing inner ring 1, a bearing outer ring 2, a retaining frame 19 and a sphere 3. The bearing outer ring 2 and the bearing inner ring 1 are respectively provided with an oil reservoir 1 4 and an oil reservoir 2 5. A plurality of oil outlets 1 6 connected to the oil reservoir 1 4 are provided on the inner wall of the bearing outer ring 2 and relative to the sphere 3. A plurality of balls 1 7 are arranged at the plurality of oil outlets 1 6. A plurality of oil outlets 2 8 connected to the oil reservoir 2 5 are provided on the inner wall of the bearing inner ring 1 and relative to the sphere 3. A plurality of balls 2 9 are arranged at the plurality of oil outlets 2 8. The balls change the sliding friction between the sphere 3 and the bearing outer ring 2 and the bearing inner ring 1 into rolling friction, thereby reducing the friction force. When the balls move, they will automatically lubricate in the oil reservoir and bring out lubricant from the oil reservoir to lubricate the sphere 3. A sealing baffle 10 is arranged between the bearing inner ring 1 and the bearing outer ring 2 and on both sides relative to the sphere 3.

[0015] To be more specific, an oil injection pipe 11 connected to an oil reservoir 4 is provided on the bearing outer ring 2, and a plug 13 is provided at the oil injection pipe 11; an oil injection pipe 12 connected to an oil reservoir 5 is provided on the bearing inner ring 1, and a plug 13 is provided at the oil injection pipe 12.

[0016] To further elaborate, both the bearing outer ring 2 and the bearing inner ring 1 are provided with mounting grooves 14, mounting portions 15 matching the mounting grooves 14 are provided at both ends of the sealing baffle 10, a sealing ring 16 is provided between the mounting grooves 14 and the mounting portions 15, and sealing rings 17 are provided on the bearing outer ring 2 and the bearing inner ring 1 and on both sides relative to the mounting portions 15, which can increase the sealing performance of the bearing, prevent external impurities from entering the interior of the bearing, and prevent the lubricant inside the bearing from flowing out, causing waste of lubricant.

[0017] To be more specific, the mounting portion 15 is U-shaped, and a sealing protrusion 18 is provided on the sealing ring 17. When the mounting portion 15 is installed, the sealing protrusion 18 on the sealing ring 17 is squeezed to achieve a better sealing effect.
