Understanding the Principle and Applications of Skeleton Oil Seals
Skeleton oil seals, also known as framework oil seals, play a crucial role in various mechanical systems by preventing the leakage of fluids such as lubricating oils. Their application spans across multiple industries, from automotive to industrial machinery. This article delves into the working principle of skeleton oil seals and their diverse applications. Sealing Principle The primary function of a skeleton oil seal is to isolate the components that need lubrication from the output components, preventing the lubricating oil from leaking. This is achieved through a combination of materials and design. The seal consists of a flexible sealing lip made from materials like nitrile rubber or silicone, and a rigid skeleton, usually made of steel, that provides structural support. The oil film between the sealing lip and the shaft is critical. It acts as a fluid lubricant, reducing friction and wear. The skeleton oil seal's effectiveness hinges on the thickness of ...
