　　Skeleton oil seals a cornerstone in the field of mechanical engineering, are indispensable for maintaining the efficiency and longevity of machinery.

　　A skeleton oil seal is a typical representative of oil seals, often referred to simply as an oil seal. The role of an oil seal is generally to isolate the parts that need lubrication in the drive components from the output components, to prevent leakage of lubricating oil.

　　The structure of a skeleton oil seal consists of three parts: the oil seal body, the reinforcement skeleton, and the self-tightening spiral spring. The seal body is divided into different parts such as the bottom, waist, blade edge, and sealing lip, according to the different positions.

　　Typically, in the free state, the inner diameter of the skeleton oil seal is smaller than the shaft diameter, that is, it has a certain “interference”. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal blade edge and the contraction force of the self-tightening spiral spring exert a certain radial force on the shaft.

　　The general function of the skeleton oil seal is to isolate the components that need lubrication from the output components in the transmission parts, so as not to allow the lubricating oil to leak1. It is commonly used for rotating shafts and is a type of rotating shaft lip seal.

　　Skeleton oil seals in preventing lubricant leakage and protecting against contamination helps ensure the smooth operation and extend the lifespan of machinery. As technology advances, we can expect to see further improvements in the design and performance of skeleton oil seals.
