Abstract

The invention belongs to the technical field of sealing structures and particularly relates to a non-rotating sealing lip rotary sealing structure. The non-rotating sealing lip rotary sealing structure comprises two adjacent parts; a sealing ring is disposed between the contact surfaces of the two parts; at least one part rotates oppositely to the other part around the rotation axis of the formerpart; and the contour shape of the sealing ring is non-rotating relative to the rotating axes of the two parts. The sealing structure is long in service life, higher in running speed, higher in allowed average pressure intensity and allowed peak value pressure intensity and lower in resisting moment and heating amount.

Description

technical field [0001] The invention belongs to the technical field of sealing structures, and in particular relates to a rotary sealing structure of a non-rotating body sealing lip. Background technique [0002] The rotary seal is a kind of dynamic seal. The rotary seal is composed of a sealing ring that provides sealing effect and a friction surface (journal, end face, etc.) , rotary joints, etc., and there are related applications in various industrial fields such as construction machinery, construction machinery and automotive equipment. It is a two-way acting rotary seal that can withstand pressure on both sides or alternating pressure. The existing rotary sealing mechanisms are all rotary body sealing structures, and their working pressure, service life, running speed, resistance torque, and calorific value cannot meet the use requirements of some occasions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...
