Background
Oil seals are a common convention designation for seals, simply referred to as lubrication seals. The mechanical element is used for sealing grease, and isolates the parts which need to be lubricated from the output parts in the transmission parts, so that the lubricating oil cannot leak. The sealing element for static sealing and dynamic sealing is called an oil seal. Many oil seals all need to prevent muddy water, and traditional muddy water oil seals are mostly combination type oil seals, and its structural feature is by two or more oil seals constitution labyrinth passageway, and inside oil seal prevents that fluid from revealing, and outside oil seal blocks the muddy water and invades. However, the traditional muddy water-proof oil seal is complex in product processing technology, low in efficiency, and the inner side surface of the external oil seal needs to be subjected to turning after being vulcanized and bonded with rubber for forming, for example, spiral lines can be generated if the roughness of the inner turning surface of the external oil seal is not in place, so that the main seal contacted with the external oil seal is worn, oil leakage is caused, and the muddy water-proof effect is poor.

Further optimize this technical scheme, a novel prevent interior support body and outer support body of muddy water oil blanket bond fixedly with interior oil blanket body and outer oil blanket body respectively.
Compared with the traditional muddy water-proof oil seal, the muddy water-proof oil seal has the beneficial effects that:
1. the main sealing lip, the outer oil seal body and the outer frame body are matched, so that the turning process is reduced, the production efficiency is improved, and the sealing failure rate is reduced;
2. the outer oil seal body, the outer frame body, the inner oil seal body, the inner frame body, the sealing ribs and the dustproof lip form a labyrinth channel, so that dust and muddy water can be effectively prevented, and the muddy water preventing effect is better;
3. the retainer ring is used for blocking the impact of the internal oil liquid and the oil sludge on the main sealing lip.
