What are the knowledge points of oil seal seals

The oil seal is an oil seal element used to seal the rotating shaft in mechanical equipment, and the oil seal cavity is basically static, so the oil seal is also called the rotating shaft lip seal;

The main purpose of the oil seal:

1. Used for the sealing of engine crankshaft and camshaft;

2. Sealing of transmission systems (such as gearboxes, hubs, axles, differentials) of cars, motorcycles and commercial vehicles;

3. Sealing of excavator, agricultural machinery and construction machinery transmission system;

4. Sealing of industrial gearboxes;

5. Sealing of hydraulic components (pumps, motors);

6. Sealing of daily mechanical washing machines;

7. Widely used in mechanical engineering and equipment processing industry;

The main features of the oil seal:

The outside of the oil seal is cylindrical to ensure the static sealing of the cavity, and the outer edge of the rubber with a metal skeleton is used; the outer edge of the exposed metal skeleton needs to be polished and plated with an anti-corrosion coating;

The sealing lip equipped with spring ensures the sealing reliability of the dynamic and static sealing of the shaft. After long-term development and research results, the structure of the sealing lip of the oil seal is improved to excellent performance, thereby improving the sealing reliability in a wider load range;

Adding a dust-proof lip, or multiple dust-proof lips in special cases, can prevent the intrusion of external pollutants and dust;
