AI Technical Summary

Technical Problem

Traditional oil seals have a simple sealing structure, which leads to leakage of media such as lubricating oil and hydraulic oil, failing to meet the lubrication requirements of equipment. Existing technologies cannot effectively solve this sealing problem. The problem that existing technologies cannot solve is that oil seals are prone to leakage due to their simple sealing structure and poor fit, resulting in resource waste and insufficient equipment lubrication.

Method used

The oil seal skeleton adopts a layered design, including the skeleton body, sealing lip, dustproof lip, medium cavity, groove and sealing ring. The sealing lip and dustproof lip cooperate to build a complete sealing system, and the sealing ring and groove strengthen the assembly seal, improving the overall reliability of the oil seal.

Benefits of technology

It achieves precise prevention of media leakage, maintains stable internal media pressure, prevents dust, impurities and moisture from entering, extends the life of equipment and oil seals, and reduces equipment wear.
