What are the knowledge points of oil seals

The oil seal is an oil sealing 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. For engine crankshaft and camshaft sealing;

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

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

4. Sealing of industrial gearboxes;

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

6. Seal of daily mechanical washing machine;

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

Main features of oil seal:

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

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

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