Description

Floating oil seal with long service life

Technical Field

The utility model relates to a mechanical seal technical field especially relates to a high life's floating oil seal.

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.

If the publication number is CN212455492U, the disclosed floating oil seal can solve the problem of oil leakage, and at the same time, can store oil to reduce wear, and collect abrasive dust, so as to improve the service life of the floating oil seal, but does not have the function of improving the strength of the rubber ring, thereby reducing the service life of the floating oil seal, and therefore, a solution to this problem is needed.
