[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The embodiment of the present application discloses a deep groove ball bearing. Figure 1-3A deep groove ball bearing includes an outer ring 1, an inner ring 14 is provided on the inner wall of the outer ring 1, a retainer 17 is provided between the outer ring 1 and the inner ring 14, a plurality of balls 16 are provided on the outer wall of the retainer 17 in sliding connection, and the plurality of balls 16 are slidably connected to the outer ring 1 and the inner ring 14, and the overall structure of the deep groove ball bearing is formed by the balls 16, the retainer 17, the outer ring 1 and the inner ring 14, which is convenient for supporting the mechanical rotating body and reducing the friction coefficient during its movement. The outer walls of both sides of the outer ring 1 are provided with a slot 2, the outer wall of the slot 2 is clamped with an upper oil ring 4, and the outer wall of the upper oil ring 4 is provided with an oil guide groove 5. The outer wall of the oil guide groove 5 is provided with a plurality of oil inlet holes 6 in a circumferential array. By clamping the upper oil ring 4 on the clamping groove 2 of the outer ring 1, lubricating oil is injected through the groove, and then the lubricating oil enters the gap between the ball 16 and the retainer 17 through the plurality of oil inlet holes 6. A fixing ring 7 for sealing the upper oil ring 4 is provided on one side of the upper oil ring 4. The outer wall of the fixing ring 7 is provided with a plurality of oil filling holes 10. The upper oil ring 4 is sealed by the fixing ring 7 to improve the overall sealing performance. Then, lubricating oil is injected into the oil guide groove 5 in the upper oil ring 4 through the plurality of oil filling holes 10, thereby facilitating operation.

[0019] The outer wall of the outer ring 1 on one side of the slot 2 is provided with a plurality of mounting grooves 3 in a linear array, and the outer walls of the plurality of mounting grooves 3 are provided with threaded holes 12. The outer wall of the fixing ring 7 is provided with a plurality of docking blocks 8 adapted to the mounting grooves 3, and the outer walls of the plurality of docking blocks 8 are provided with fixing bolts 9. The plurality of docking blocks 8 on the fixing ring 7 are docked with the plurality of mounting grooves 3, and then the plurality of fixing bolts 9 are docked and fixed with the threaded holes 12 in the mounting grooves 3, thereby fixing the fixing ring 7 on the outer ring 1 and also fixing the upper oil ring 4.

[0020] The outer wall of the upper oil ring 4 is fixedly connected to two limit blocks 15, and the outer wall of the inner ring 14 is provided with two limit grooves 13 adapted to the limit blocks 15. The limit blocks 15 and the limit grooves 13 improve the installation stability of the upper oil ring 4.

[0021] The outer walls of the plurality of oil filling holes 10 are each provided with a sealing gasket 11 for sealing the oil filling holes 10 . The plurality of sealing gaskets 11 facilitate sealing the plurality of oil filling holes 10 when no lubricating oil is injected.

[0022] The implementation principle of a deep groove ball bearing in an embodiment of the present application is as follows: first, the upper oil ring 4 is docked with the clamping groove 2 on the outer ring 1, and the limiting block 15 is used to limit it with the limiting groove 13, so that the upper oil ring 4 is installed, and then the multiple docking blocks 8 on the fixing ring 7 are docked with the multiple mounting grooves 3 on the outer ring 1, and the multiple fixing bolts 9 are docked with the threaded holes 12 in the mounting groove 3, and the fixing ring 7 is installed on the outer ring 1, and the upper oil ring 4 is fixed at the same time, thereby improving the sealing degree of the deep groove ball bearing. When lubricating oil needs to be filled after long-term use, the multiple sealing gaskets 11 are separated from the multiple oil filling holes 10, so that the oil filling operation is performed through the multiple oil filling holes 10, and the lubricating oil enters the oil guide groove 5 on the upper oil ring 4, and then by continuously injecting lubricating oil, the lubricating oil passes through the multiple oil inlet holes 6 opened on the upper oil ring 4 and enters the balls 16 and the retaining frame 17, thereby filling them with lubricating oil.
