Abstract

The invention discloses a floating sealing pair which comprises two floating sealing rings which are oppositely arranged; a bright belt is arranged between the opposite end surfaces of the two floating sealing rings, namely a contact type wear-resistant sealing ring surface; and the inner diameter of the bright belt is equal to the nominal inner diameter of each floating sealing ring. According tothe technical scheme of the invention, the problems that the service life of a bright belt of an existing floating sealing pair is short, and in addition, external pollutants, such as muddy water andsandy soil, easily invade into a sealing system, so that stable running of lubrication and sealing oil films is not facilitated, and sealing failure of the floating sealing pair is accelerated can besolved.

Description

technical field [0001] The present application relates to the technical field of sealing, in particular, to a floating sealing pair. Background technique [0002] It consists of a pair of relatively wear-resistant metal rings (ie: floating seal rings. The inventor artificially divides the section of the floating seal ring into the functional area of ​​the sealing surface and the functional area of ​​the support body, and the two oppositely arranged contact parts in the functional area of ​​the sealing surface A wear-resistant sealing ring surface is called a bright belt) and a pair of rubber sealing rings. The energy storage is assembled in the combined cavity of the outer cone of the support and the inner cone of the floating seal seat). [0003] The bright belt of the existing floating seal pair has a short service life, and external muddy water, sand and other pollutants are easy to invade the sealing system, which is not conducive to the stable operation of lubrication ...
