Description

Technical Field

[0001] The utility model belongs to the technical field of oil seal manufacturing, and particularly relates to an oil seal ring with a multi-layer structure. Background Technique

[0002] An oil seal is the common name for a general seal. Simply put, it is the seal of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system and also generally refers to general liquid substances). It isolates the components that need to be lubricated in the transmission components from the output components, so as to prevent the leakage of lubricating oil. The seals used for static seals and dynamic seals (generally reciprocating motions) are called oil seals. The representative form of an oil seal is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely wrapped by rubber. Generally, the oil seal often refers to this kind of tc skeleton oil seal.

[0003] There are still some defects in the existing oil seal rings with multi-layer structures. During the use of most oil seal rings with multi-layer structures, the skeleton and the rubber embryo are placed in the mold cavity together. After heating and vulcanization, they become skeleton oil seals. Due to the shielding of the skeleton, the molten colloid cannot smoothly fill the gap between the skeleton and the mold cavity, and the wear resistance is poor. Therefore, we propose an oil seal ring with a multi-layer structure. Content of the Utility Model
