[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0026] According to the overall structure of the device, the lubricating oil can be input into the oil groove 5 through the oil filling hole 8 in advance, and then the sealing column 6 is threadedly connected to the oil filling hole 8 through the knob 7 for sealing. The lubricating oil entering the oil groove 5 will be absorbed by the oil-absorbing sponge ring 4 in the mounting groove 2. When the outer ring of the bearing 1 rotates, the lubricating oil absorbed by the oil-absorbing sponge ring 4 will slowly be thrown out from the oil-throwing hole 3 and drip onto the ball of the bearing 1 for self-lubrication, so that the bearing 1 does not need to be frequently disassembled to add lubricating oil, and the setting of the support column 13 and the reinforcing rib 14 greatly increases the strength of the oil groove 5 and the mounting groove 2, thereby increasing the strength of the bearing 1. When the bearing 1 is working, the heat generated by friction can be conducted to the heat-conducting column 11 through the thermal conductive silicone tube 10 in the heat dissipation hole 9, and then the heat dissipation area is further increased through the heat sink 12, so that the passive heat dissipation effect of the bearing 1 is better.

[0027] like Figure 2-4As shown, the self-lubricating structure includes an oil groove 5, a mounting groove 2, an oil-absorbing sponge ring 4 and an oil-slinging hole 3.

[0028] By setting the oil groove 5, mounting groove 2, oil absorption sponge ring 4, oil throwing hole 3, oil filling hole 8, sealing column 6, knob 7, support column 13 and reinforcing rib 14, the lubricating oil can be input into the oil groove 5 through the oil filling hole 8 in advance, and then the sealing column 6 is threadedly connected with the oil filling hole 8 through the knob 7 for sealing, and the lubricating oil entering the oil groove 5 will be absorbed by the oil absorption sponge ring 4 in the mounting groove 2. When the outer ring of the bearing 1 rotates, the lubricating oil absorbed by the oil absorption sponge ring 4 will slowly be thrown out from the oil throwing hole 3 and drip onto the ball of the bearing 1 for self-lubrication, so that the bearing 1 does not need to be frequently disassembled to add lubricating oil, and the setting of the support column 13 and the reinforcing rib 14 greatly increases the strength of the oil groove 5 and the mounting groove 2, thereby increasing the strength of the bearing 1.

[0029] like Figure 2 As shown, the auxiliary heat dissipation component includes a heat dissipation hole 9, a thermally conductive silicone tube 10 and a thermally conductive column 11.

[0031] Working principle: when the bearing 1 needs to be lubricated, the lubricating oil is input into the oil groove 5 through the oil filling hole 8 in advance, and then the sealing column 6 is threadedly connected to the oil filling hole 8 through the knob 7 for sealing.

When the outer ring of the bearing 1 rotates, the lubricating oil absorbed by the oil absorption sponge ring 4 will slowly be thrown out from the oil throwing hole 3 and drip onto the ball of the bearing 1 for self-lubrication. The setting of the support column 13 and the reinforcement rib 14 greatly increases the strength of the oil groove 5 and the mounting groove 2. When the bearing 1 is working, the heat generated by friction can be conducted to the heat conducting column 11 through the thermal conductive silicone tube 10 in the heat dissipation hole 9, and then the heat dissipation area is further increased through the heat sink 12.
