Description
Technical Field
The utility model relates to a sliding bearing, in particular to an oil-free lubrication bearing with vertical oil grooves on the inner surface and the outer surface.
Background
The common sliding bearing is in a circular shaft sleeve shape, but for a circular sliding bearing used on a gearbox, only copper alloy can be used for casting a blank of the sliding bearing with an annular oil groove on the inner surface, then the sliding bearing with the vertical oil groove is processed on a milling machine and is pressed in the gearbox sleeve, the conditions of rotation and displacement of the outer surface of the bearing can occur after long-term use, lubricating grease is often required to be added on the surface of a friction pair, and the maintenance is troublesome.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an oil-free lubrication bearing with a novel structure, a fixed outer surface during installation and use, long service life and low manufacturing cost, wherein the inner surface and the outer surface of the oil-free lubrication bearing are provided with vertical oil grooves.
In order to achieve the purpose, the utility model adopts the technical scheme that: the composite material plate is rolled into a straight barrel-shaped sliding bearing, a hasp is arranged on the straight barrel-shaped sliding bearing, the hasp is used for locking two ends of the composite material plate in an overlapping manner, and 4-8 axial oil grooves are respectively formed in the inner surface and the outer surface of the straight barrel-shaped sliding bearing.
The thickness of the steel base layer is 1.47-1.50 mm.
The thickness of the copper powder layer is 0.5 mm.
The four axial oil grooves on the inner surface and the four axial oil grooves on the outer surface are staggered in the circumferential direction.
The hasp is a circular hasp.
According to the oil-free lubrication bearing with the vertical oil grooves on the inner surface and the outer surface, which is designed according to the technical scheme, in the manufacturing process, the steel plate is used as a base material according to the size of the sliding bearing, a composite material plate of a copper powder layer is sintered on the surface of the base material, the composite material plate is formed by rolling, and four uniform axial oil grooves on the inner surface and the outer surface are processed. The bearing has the characteristics of low manufacturing cost, simple process, fixed outer surface during installation and use, no rotation and displacement of the bearing during use, more durability in use, and capability of realizing fixed linear reciprocating motion by the aid of special inner and outer axial oil grooves. The product does not need to be added with lubricating oil or lubricating grease frequently when in use. The product is mainly applied to fixed mechanisms for adjusting linear motion, reciprocating motion, height, length and the like.

Detailed Description
The utility model is further described with reference to the following figures and specific embodiments.
As shown in figure 1, the outer surface of the steel base layer 1 is 1.47-1.50 mm thick, a composite material plate made of a copper powder layer 2 with the thickness of 0.5 mm is sintered on the inner surface of the steel base layer, and circular matched hasps 3 are arranged at two ends of the plate. Then, the composite material plate is rolled into a straight barrel-shaped sliding bearing as shown in fig. 2 to 4, the hasp 3 is used for locking two ends of the composite material plate in an overlapping manner, 4 inner axial oil grooves 4 and 4 outer axial oil grooves 5 are respectively formed on the inner surface and the outer surface of the straight barrel-shaped sliding bearing, and the inner axial oil grooves 4 and the outer axial oil grooves 5 are mutually staggered in the circumferential direction.
It should be understood that the above examples are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. All changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
