[0002] Multi-lip rubber sealing rings are composite rubber seals with more than two sealing lips. They are generally used as mechanical components to seal grease. Multi-lip rubber sealing rings isolate the parts that need lubrication in the transmission components from the output components to prevent the lubricating oil from leaking. Multi-lip rubber sealing rings have good sealing performance, long service life, heat resistance, wear resistance, aging resistance, simple structure, easy disassembly and convenient inspection.
[0003] A Chinese patent with application number 202123328207.6 discloses a multi-lip rubber sealing ring. By setting an oil chamber on the inner side of the ring body to store oil, the inner ring of the sealing ring can remain lubricated for a longer time. When the grease in the oil chamber of the sealing ring is used up, the grease can be replenished in time by inserting a needle into the oil inlet hole. The oil inlet hole is set to a funnel shape with a contraction in the middle so that it can be automatically closed, and the grease is prevented from being squeezed out of the oil inlet hole when oil replenishment is not needed. However, the oil inlet hole structure is provided on the rubber ring body, and extrusion deformation will occur when the ring body is subjected to force, causing grease to leak out from the oil inlet hole.
