Combined continuous filling type solid lubricating bearing

Abstract

The invention discloses a combined continuous filling type solid lubricating bearing, which comprises a base body and a solid lubricant, wherein the base body is composed of an outer carbon steel layer and an inner copper alloy layer; the outer carbon steel layer is composed of two semi-circular parts which are connected through bolts; a notch is formed in the outer side of the top end of each semi-circular part; an adjusting gasket is arranged in the notch; the inner copper alloy layer is composed of four arc-shaped copper alloy inner layer blocks; triangular strip-shaped solid lubricants are embedded between each two adjacent copper alloy inner layer blocks and are distributed on two sides of the copper alloy inner layer blocks in a staggered manner; two blind holes are tangentially formed in one end of each copper alloy inner layer block; a spring is arranged in each blind hole; one end of each spring is fixed in each blind hole and the outer end of each spring props against each triangular strip shaped solid lubricant. The bearing is high temperature resistant, high load resistant, good in self-lubricating and wear resistant under relatively large load condition and is simple in structure, convenient to dismount, and has no requirement on types of the solid lubricant; the solid lubricant is easy to replace, and the bearing can be continuously filled with the solid lubricant.

Description

technical field [0001] The invention relates to a solid lubricating bearing, in particular to a radial sliding bearing of combined continuous filling type solid lubricant. Background technique [0002] At present, metal-based embedded solid self-lubricating bearings have been widely used. This kind of bearings is a novel lubricating bearing with the characteristics of metal bearings and self-lubricating bearings. The metal matrix such as brass bears the load, and the special formula of solid lubricating materials acts as a lubricant. . The metal substrate bears most of the load during the friction process. After friction, the solid lubricant in the holes or grooves is transferred or reversed to the friction surface, forming a well-lubricated, firmly attached and evenly covered solid transfer film on the friction surface, which greatly reduces friction and wear. There are two deficiencies in the prior art. One is to rely on a single-layer metal matrix to bear the load, and...

Problems solved by technology

There are two deficiencies in the prior art. One is to rely on a single-layer metal matrix to bear the load, and the bearing size is small, which is insufficient for large loads and large sizes; the second is that although the bearing made by this method improves the lubrication performance of the bearing, The sustainable filling of solid lubricants for bearings is insufficient, mainly relying on the thermal expansion of the solid lubricant inlay to fill the solid lubricant film, the sustainability is insufficient, and due to the limitation of thermal expansion coefficient, the types of solid lubricants are very limited
