The sealing principle of the floating oil seal is that after the O-ring is sealed, the two floating rings are deformed through axial compression, and pressure is generated on the sealing end face of the floating ring. As the seal end face wears evenly, the elastic energy stored in the O-ring seal is gradually released, thus playing the role of axial compensation. The sealing surface can maintain good coordination within the set time, and the general sealing life is more than 5000h.
Floating oil seal is a special type of mechanical seal. It is a compact mechanical seal suitable for harsh working environments. It has strong anti-pollution ability, wear resistance, impact resistance, reliable workability, and automatic end wear. Compensation, simple structure, etc., are the most common applications in engineering machinery products. It is also widely used in various conveyors, sand handling equipment and concrete equipment. In coal mining machinery, it is mainly used for the sprockets and deceleration of scraper conveyors. And the shearing mechanism, rocker arm, roller, etc. of the shearer. This kind of sealing product is more common and mature in the application of engineering machinery and equipment.
Floating seals are generally used in planetary reducers in the traveling parts of engineering machinery, on the end faces of dynamic sealing components. Due to its high reliability, it can also be used as a dynamic seal for the output shaft of the dredger bucket wheel. This seal is a mechanical seal, usually made of iron alloy. The floating ring material matches the nitrile O-ring seal. Floating rings are used in pairs, one rotates with the rotating part and the other is relatively stationary, which is very different from the oil seal ring.
