[0029] The anti-oil leakage component includes a guide ring 4, a first guide hole 5 is opened inside the guide ring 4, a sponge 12 is arranged inside the sealing ring body 1, the sponge 12 and the guide ring 4 are used to guide the sealing ring body 1 to prevent oil leakage, the number of the first guide holes 5 is set to multiple, and the multiple first guide holes 5 are evenly distributed inside the guide ring 4, a cavity is opened inside the sealing ring body 1, and the sponge 12 is located inside the cavity. The anti-oil leakage component can reduce the loss of lubricating oil when oil leakage occurs. Specifically, when the bearing leaks oil, when the lubricating oil flows to the guide ring 4 of the sealing ring body 1, the lubricating oil will flow into the interior of the sponge 12 through the multiple first guide holes 5. Since the sponge 12 has adsorption properties, it can play a role in storing oil when oil leakage occurs, thereby reducing the loss of lubricating oil.
[0030] Reference Figure 1-Figure 5Two fixed blocks 6 are fixedly connected inside the sealing ring body 1, a leakage hole 7 is opened between the two fixed blocks 6, and the leakage hole 7 is located at the bottom of the sponge 12. The tops of the two fixed blocks 6 are set as inclined surfaces, and guide blocks 10 are provided at the bottom of the two fixed blocks 6. The cross-sectional shape of the guide block 10 is set to be triangular. A second guide hole 8 is opened inside the outer ring 2. The number of the second guide holes 8 is set to be multiple. The multiple second guide holes 8 are arranged in a ring shape along the axis of the outer ring 2. Each second guide hole 8 is located at one end of the guide block 10. Extension blocks 14 are fixedly connected to both ends of the guide ring 4. Grooves 13 are opened on one side of the outer ring 2 and the inner ring 3. A spring block 15 is fixedly connected inside each groove 13. Each extension block 14 They are all located above the spring block 15. After the sponge 12 absorbs the lubricating oil, due to the action of the spring block 15, by gently pressing the guide ring 4, the guide ring 4 will squeeze the sponge 12, and the lubricating oil inside the sponge 12 can be squeezed out. The lubricating oil will flow out from the second guide hole 8 through the leakage hole 7, and will lubricate the outer wall of the outer ring 2, so that the sealing ring body 1 can achieve the effect of reusing the lost lubricating oil, reduce the erosion and damage of the oil leakage to the bearing and related equipment, extend their service life, and avoid the pollution of the surrounding environment and the accumulation of oil stains caused by the leakage of the lubricating oil, keep the equipment and working environment clean, reduce the frequency of equipment failure and shutdown maintenance due to oil leakage, and improve the operation efficiency of the equipment.

Through the setting of the sealing lips 11, the sealing performance of the sealing ring body 1 and the bearing during use can be guaranteed.
[0033] Working principle: When the bearing leaks oil, when the lubricating oil flows to the guide ring 4 of the sealing ring body 1, the lubricating oil will flow into the interior of the sponge 12 through multiple first guide holes 5.

After the sponge 12 absorbs the lubricating oil, due to the action of the spring block 15, by gently pressing the guide ring 4, the guide ring 4 will squeeze the sponge 12, and the lubricating oil inside the sponge 12 can be squeezed out. The lubricating oil will flow out from the second guide hole 8 through the leakage hole 7, and will lubricate the outer wall of the outer ring 2.
