Abstract

The invention relates to the technical field of manufacturing of movable sealing elements, in particular to a clamping groove-type floatable sealing ring. In the prior art, two floatable sealing rings rotate relatively during the operation of the floatable sealing ring, oil films are likely to generate between an O-shaped rubber sealing ring and a floatable sealing cavity, resulting in decreased friction resistance between the O-shaped rubber sealing ring and the floatable sealing cavity and relative movement, so that dust and particles enter between the O-shaped rubber sealing ring and the floatable sealing cavity to destroy the O-shaped rubber sealing ring, and the floatable sealing ring loses the sealing effect. According to the clamping groove-type floatable sealing ring, an axial tooth boss is arranged at one side of the floatable sealing ring opposite to the floatable sealing cavity, a groove is arranged on the floatable sealing cavity corresponding to the tooth boss, and the tooth boss on the floatable sealing ring is clamped in the groove on the corresponding floatable sealing cavity when the floatable sealing ring is installed. The clamping groove-type floatable sealing ring has the advantages of compact structure, convenient installation, low fault rate and long service life.
