Description

Floating sealing ring

Technical Field

The application belongs to the mechanical sealing element field, especially relates to a floating seal ring.

Background

The floating oil seal generally includes a floating oil seal ring and a seal ring fitted around an outer peripheral surface of the floating oil seal ring. In floating oil seals, floating oil seal rings (and seals) are typically used in pairs, one rotating with a rotating component (e.g., a rotating shaft) and the other relatively stationary. The sealing principle of the floating oil seal is as follows: the two floating oil seal rings generate pressing force on two opposite end faces of the floating oil seal rings by means of deformation of the sealing rings after axial compression. Because of the relative rotation between the two floating oil seal rings, the abrasion generated at the two opposite end surfaces is large.
