Metal matrix inlaid elastic self-lubricating sliding bearing

Abstract

The invention relates to the technical fields of polymer materials and sliding bearings, in particular to a metal matrix inlaid elastic self-lubricating sliding bearing which comprises a rubber cushion layer (1), a polymer bearing strip (2) and a metal matrix (3); and more than 6 axial grooves with the cross sections being a ring fan shape and similar to a ladder shape are arranged on the circumference of the inner surface of the upper edge of the metal matrix (3), the bottom of each groove is provided with the rubber cushion layer (1), and the polymer bearing strip (2) which is consistent with the groove shape at normal temperature is inlaid in, and the inner surface of the polymer bearing strip (2) on the inner cylindrical surface of the polymer metal matrix (3) forms the friction surface of the bearing. The metal matrix inlaid elastic self-lubricating sliding bearing simultaneously has the self-lubricating and the wear resistant performance of the polymer material and the elastic performance of rubber, not only can meet the flexible requirements of a shaft but also can effectively prolong the service life of the bearing, not only is applicable to the application fields of all common inlaid solid self-lubricating bearings, but also is applicable to occasions on which the shafts are quite long, the bending and deformation are easy, the vibration is easy to produce, the bearing is easy to wear and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials and sliding bearings, and relates to an elastic self-lubricating sliding bearing in which a certain number of rubber sheets and polymer bearing bars are embedded circumferentially on a metal bearing substrate along the inner surface. Background technique [0002] Sliding bearings are very common components in mechanical systems, and are also key components that are directly related to the normal operation of mechanical equipment or systems. With the rapid development of science and technology, the requirements for bearing performance are getting higher and higher, especially in the occasions where the shaft length is large and prone to bending, vibration and severe wear, etc., the requirements for the elasticity, wear resistance and lubrication of the bearing have been proposed. strict requirements. At present, the research on sliding bearings is mainly to improve the bearing capacity o...

AI Technical Summary

Problems solved by technology

It mainly uses the elasticity of the rubber sheet, the wear resistance and self-lubricating properties of the polymer bearing bar to overcome the defects of rubber bearings that are easy to wear and metal bearings with insufficient elasticity and has good lubricating properties, and achieves good running stability and long service life.
