[0033] A deep groove ball bearing with a lubrication function comprises an outer ring 1 and an inner ring 2, a plurality of balls 4 are arranged in the middle between the outer ring 1 and the inner ring 2, protective covers 3 are arranged at the edges between the outer ring 1 and the inner ring 2, a first arc groove 10 is opened on the inner wall of the outer ring 1, a second arc groove 20 is opened on the outer wall of the inner ring 2, a plurality of clamping blocks 30 are arranged at the edge of the outer wall of the protective cover 3, and clamping grooves 11 are opened on the outer walls on both sides of the outer ring 1 at positions corresponding to the clamping blocks 30.

[0034] In this embodiment, the card blocks 30 are evenly distributed in a ring shape, the card blocks 30 and the protective cover 3 are an integrally formed structure, the width of the outer wall of the card block 30 is adapted to the width of the inner wall of the card slot 11, and the card block 30 is plugged into the card slot 11, which facilitates the stable plug-in installation of the protective cover 3.

[0035] Furthermore, fixing holes 300 are provided on the blocks 30, flat head screws 301 are provided in the fixing holes 300, screw holes 110 are provided at the bottom of the slots 11, the flat head screws 301 are threadedly connected with the screw holes 110, the flat head screws 301 pass through the fixing holes 300 and cooperate with the screw holes 110, so as to achieve stable fixed installation cooperation between the protective cover 3 and the outer ring 1.

[0036] Specifically, the protective cover 3 is in a circular shape, and the width between the outer wall and the inner wall of the protective cover 3 is adapted to the width between the outer ring 1 and the inner ring 2. The protective cover 3 fully fills the gap between the outer ring 1 and the inner ring 2, so as to fully protect and cooperate with the internal balls 4 and reduce the influence of external environmental interference.

[0037] It should be noted that the balls 4 are distributed in a ring shape with equal spacing, and the balls 4 are clamped between the first arc groove 10 and the second arc groove 20. With the cooperation between the first arc groove 10 and the second arc groove 20, the stability of the clamping installation of the balls 4 is increased.

The application of the lubricating grease increases the flexibility of the ball 4 in rotation, thereby increasing the overall lubrication function.

[0040] When the deep groove ball bearing with lubrication function of this embodiment is in use, the user manually installs multiple balls 4 between the outer ring 1 and the inner ring 2, and the balls 4 are arranged in sequence between the first arc groove 10 and the second arc groove 20. The user manually fills the third arc groove 31 on the protective cover 3 with lubricating paste, and then plugs the protective cover 3 into the card slot 11 through the clamping block 30, manually installs the flat head screw 301 in the fixing hole 300, and threadedly connects it with the screw hole 110 to increase the stability of the installation of the protective cover 3. When the balls 4 need to be fully lubricated, the flat head screw 301 is manually removed and the protective cover 3 is opened to facilitate the full application of corresponding lubricating oil to the balls 4. The overall combination is easy to install and convenient for manual operation.
