Sealing structure of floating oil seal

  • Author:Alice
  • Release on:2021-05-20
The floating oil seal is an end face sealing device composed of two floating metal rings and two rubber O-rings. The end faces of the two floating seal rings are close to each other while sliding relative to each other.

Floating seal ring is a saddle-shaped circular seal ring made of wear-resistant metal sealing material. Floating seal rings are used in pairs, one is fixed, and the other rotates with the rotating seal. The end surface of the floating seal ring close to the nominal outer diameter and acting as the sealing surface is the sealing surface. The sealing ring surface with the outer surface roughness of 0.1pm is a bright band.

What role does the floating O-ring seal play? O-shaped sealing ring The large-diameter O-shaped cross-section rubber sealing ring is installed between the outer cone surface of the floating seal ring and the inner cone surface of the floating seal seat, which serves as a static seal. At the same time, the sealing surface of the floating seal ring maintains a certain axial compression force by its compression deformation.

What role can the floating sealing seat play? The floating seal seat contains a conical inner cavity, and a sealing part that is installed with a floating seal and can adjust the tightness of the floating seal ring. A set of floating encapsulation is contained in two symmetrical shape and same size floating seal seat cavity.
