Background
Oil seals are a common term for seals, simply the seal of lubricating oil. It is a mechanical element used to seal grease (oil is the most common liquid substance in transmission systems, also generally referred to as a liquid substance), and it isolates the parts of the transmission parts that need to be lubricated from the output parts, so as not to allow the lubricating oil to leak. Static seals and dynamic seals (generally reciprocating) are called oil seals. The representative form of oil seal is TC oil seal, which is a rubber fully covered double-lip oil seal with self-tightening spring, and the general oil seal is often referred to as TC framework oil seal.
The existing multi-lip mode is easy to damage and poor in eccentricity resistance, or a more complex sealing structure is adopted, dust and sediment are still accumulated around a sealing body, and once large eccentricity or axial movement occurs, the dust prevention effect is immediately ineffective. Therefore, an oil seal with a dust-proof mud-proof lip is provided.
