Abstract
The utility model relates to a dry friction self-lubricating bearing with a ball surface adjusting core, comprising an inner sleeve and an outer sleeve. One side of the outer sleeve is provided with an elastic opening, the left part and the right part of the inner margin of the outer sleeve are respectively provided with one installation opening, and the inner margin of the outer sleeve is a concave surface. The outer margin of the inner sleeve is a convex surface. The inner sleeve is the structure of an inner ring and an outer ring, the outer ring is a common metallic material, and the inner ring is a self-lubricating material. The outer sleeve and the inner sleeve of the dry friction self-lubricating bearing with a ball surface adjusting core are in transition fit. The inner ring and the outer ring of the inner sleeve of the dry friction self-lubricating bearing with a ball surface adjusting core are in interference fit. Due to the fact that the elastic opening is on the outer sleeve, the optimum position of the dry friction self-lubricating bearing with a ball surface adjusting core is fixed by the pressure of the bolt of a tile box cover on the outer sleeve of the dry friction self-lubricating bearing with a ball surface adjusting core. The generation of the phenomena that friction coefficient increase, the clamping and stooping of the dry friction self-lubricating bearing with a ball surface adjusting core, inclined abrasion, etc. which are caused due to the parallel degree problem of a bearing seat can be solved.
Description
The utility model belongs to dry friction self-lubricating design bearing and manufacturing technology field.
Industrial employed dry friction self-lubricating bearing has two kinds at present, and one is overall structure, and for self lubricating material is made, another kind is the Internal and external cycle structure, and overcoat is an ordinary metallic material, and interior cover is a self lubricating material, and interference is installed and formed.But both are a little less than the impact resistance.In addition, also because the parallelism problem of bearing support and cause the increase friction factor easily, bearing jam and grind phenomenon such as inclined to one side and take place.
It is the spherical aligning dry friction self-lubricating bearing that the identical structure of sphere, overcoat have elastic opening that the purpose of this utility model provides a kind of interior overcoat.
The utility model structure is as shown in drawings: be made of overcoat and interior cover, overcoat has an elastic opening.The inner edge of overcoat is a concave surface, and the outer rim of interior cover is a convex surface, and both match.Interior cover is the Internal and external cycle structure, and the outer ring is an ordinary metallic material system, and inner ring is the dry friction self-lubricating material.Portion respectively has one gap is installed about the overcoat inner edge.Interior overcoat transition fit is installed and is formed.
The utility model adopts the male and female face structure that matches, and the opening that puts outward is when bearing transfers to ideal position, by the bolt pressure that is pressed in watt lid on the bearing outside optimum position of bearing to be fixed.Because what the utility model adopted is the spherical aligning structure, can freely adjust its use angle within the specific limits, promptly when the diaxon bearing is basic not parallel, also can adjust the center angle.Thereby enlarged the using scope of bearing, improved integral installation precision and working life.

Fig. 2 is the utility model sectional drawing
The utility model relates to powder metallurgical production technique, and with reference to specification and accompanying drawing, the processing assembling can realize.
Embodiment:
One side of overcoat (1) has elastic opening (4), and portion respectively has an installation gap (5) about its inner rim, and the inner edge of overcoat is a concave surface.The outer rim of interior cover (2) is a convex surface, and interior cover inner ring (3) is a self lubricating material.Overcoat and interior cover are transition fit.The inner ring and the outer ring of interior cover are interference fit.
Claims (1)
1, spherical aligning dry friction self-lubricating bearing, constitute by overcoat (1) and interior cover (2), a side that it is characterized in that overcoat has elastic opening (4), portion respectively has one gap (5) is installed about the overcoat inner edge, the inner edge of overcoat is a concave surface, and the outer rim of interior cover is a convex surface, and interior cover is the Internal and external cycle structure, the outer ring is an ordinary metallic material, and inner ring (3) is a self lubricating material.
