Problems solved by technology

However, there are the following deficiencies in actual use: First, the sealing ring is usually cut and blanked from the plate by a shearing machine. When the shearing machine is blanked, it will be affected by factors such as the shear gap and the bevel angle of the blade, which will cause the sealing ring to collapse. Defects such as burrs and edge tears make the sealing section uneven and reduce the sealing effect
The second is that the surface of the sealing ring cannot store lubricating grease, and the actual work is dry friction, the wear rate is higher than that of the friction pair, and the sealing effect is easily reduced due to wear

Abstract

The invention discloses a friction pair sealing structure which comprises a metal slide plate, a nonmetal slide plate and a sealing strip. Lubricating oil films A are arranged between the metal slide plate and the nonmetal slide plate, the sealing strip is arranged on the periphery of the nonmetal slide plate, the upper surface or the lower surface of the sealing strip clings to the metal slide plate, an annular groove is formed in the clinging surfaces of the sealing strip and the metal slide plate and is filled with lubricating grease, and the lubricating grease and the lubricating oil films A are connected with one another to form an integral continuous lubricating oil film when a friction pair slides. The friction pair sealing structure has the advantages that groove structures are formed in the surfaces of sealing rings, the lubricating grease is smeared in the groove when the friction pair sealing structure is used, and accordingly the self-lubricating properties of the sealing rings can be enhanced; the lubricating oil film is formed on the surface of the friction pair and is sucked among the metal slide plate, the nonmetal slide plate and the sealing rings, the sealing rings can be driven to be subjected to transition from dry friction to fluid friction, the nonmetal slide plate can be subjected to transition from mixed friction to fluid friction, the friction pair sealing structure is low in slide resistance, contact friction of micro-convex bodies on the surface of the friction pair can be reduced, accordingly, the friction pair sealing structure is good in abrasion resistance and long in service life, and obvious sealing and lubricating effects can be realized.

Description

technical field [0001] The invention belongs to the technical field of bridge supports, and in particular relates to a friction pair sealing structure. Background technique [0002] The friction pair is the core component of the bridge support, and it is also the key to the service life of the support. Therefore, its dust-proof seal is very important. Once dust and impurities enter the friction surface, it will affect the sliding or rotating function of the friction pair, thereby affecting the entire Service life of bridge bearings. [0003] At present, the bridge support mainly realizes the equal deformation sealing effect by setting a sealing ring of the same material as the slide plate around the friction pair. The sealing ring is used to achieve the sealing effect; the basin-type rubber bearing is provided with a flat sealing ring around the plane friction pair to achieve the sealing effect; the hyperboloid shock-absorbing bearing is provided with a curved surface seali...
