Abstract
The utility model relates to a steel-based copper alloy embedded bearing with solid lubricant which adopts a high-quality carbon structural steel as the base which a high-strength copper casting-alloy layer integrated on the inside wall; while a solid lubricant is mounted in a through-hole between the inside wall and the outside wall of a bearing or in a blind hole on the inside wall. The utility has the advantages of high bearing capacity, high shock resistance, small friction and wearable structure, the bond strength between the steel base and the copper alloy is more than or equal to 150N/mm<2>, and the ultimate PV value is less than or equal to 1.65 N/mm<2>.m/s, so as to be capable to be widely used under a heavy-load low-speed operating condition in which the lubricant film is hard to form in fields such as a hoisting machine, a roll gang, an injection machine or a high-precision mold, etc.
Description
Affiliated technical field
The utility model belongs to the bearing group in International Patent Classification (IPC), i.e. F16C, particularly steel based copper alloy inlaid solid lubrication bearing.
Background technique
As everyone knows, Cuprum alloy axle sleeve or copper alloy inlaid solid lubrication agent bearing have history for many years at home and abroad, but because these two kinds of products all are to adopt the manufacturing of integrated type Cu alloy material, though the latter has the advantage of improving greasy property and increasing wear resistance, bearing capacity is little, the characteristics of shock resistance difference but all exist, and meanwhile also will consume the non-ferrous metal of a large amount of costlinesses.Steel bushing then has the characteristics that bearing capacity is big, shock resistance is good, so some producer has adopted the method for on steel bushing bore area copper facing or spraying and sintering layer of copper bisque.Because copper-plated thickness is restricted, and can not bear the operating mode of heavy-duty low-speed and poor lubrication, working life is short.Though and spraying or sintered copper powder make moderate progress, the combination force of invar base and copper powder layer is poor, and actual measurement is not more than 16N/mm
2Simultaneously because of the compactness difference of copper powder layer is that density is low, a little less than the anti scuffing ability, weakness such as bearing capacity is little, though manufacture cost has reduced, performance substitutes so should be had the novel sliding bearing of many-sided good characteristics not as good as the Cuprum alloy axle sleeve.
The model utility content
The purpose of this utility model provides a kind of steel based copper alloy inlaid solid lubrication bearing, it not only combines the characteristic that structural strength height, bearing capacity are big, anti-impact force is strong of base steel material and as the characteristics of the low friction of the Cu alloy material of friction pair, and the solid lubricant of inlaying has more played and has improved greasy property, increases the good characteristics of wear resistance.
It is as follows to disclose new technological scheme:
Steel based copper alloy inlaid solid lubrication bearing is sleeve-like, is matrix with the carbon constructional quality steel, and inwall is combined with high-intensity cast copper alloy layer; Through hole or on the inwall blind hole, stud with solid lubricant between the inside and outside wall of bearing.
The junction plane of matrix and copper alloy layer is molten state.
Press the sample that such scheme is made, the adhesive strength of steel base and Cuprum alloy is up to 150N/mm
2More than, be equivalent to more than the combination force octuple of steel base sintered copper powder; The thickness of copper alloy layer only need be controlled at 〉=1mm, compares with Cuprum alloy axle sleeve or copper alloy inlaid solid lubrication bearing, can save the non-ferrous metal more than 70%; Moreover the utlity model has good friction and wear characteristic, test result shows that limit PV value can be up to 1.65N/mm
2More than the m/s.This is that common Cuprum alloy axle sleeve is unapproachable, and suitable with the copper alloy inlaid solid lubrication bearing of manufacture cost costliness.Can be widely used in various heavy-duty low-speeds be difficult to form under the lubricant film operating mode such as fields such as Hoisting Machinery, rollgang, injection machine and high-precision molds.Formed transfer membrane at work owing to solid lubricant in addition, even under no oil condition, equally can proper functioning.

Embodiment
Steel based copper alloy inlaid solid lubrication bearing is sleeve-like, is matrix 1 with the carbon constructional quality steel, and the inwall of matrix 1 is combined with high-strength casting copper alloy layer 3, and the junction plane of matrix 1 and copper alloy layer 3 is molten state.As Fig. 2, shown in Figure 4, be inlaid with the solid lubricant 2 that the macromolecule packing material is formed on bearing cross hole or the inwall blind hole.Thickness 〉=the 1mm of copper alloy layer 3.The 15%-25% that the friction area of solid lubricant 2 accounts for the pivot friction area is good.
Embodiment 1 is applicable to the middle small dimension of steel based copper alloy inlaid solid lubrication bearing and the bearing of common wall thickness, and solid lubricant 2 is inlaid in the through hole between the inside and outside wall of bearing.
Embodiment 2 is applicable to the big specification of steel based copper alloy inlaid solid lubrication bearing and increases the bearing of wall thickness that solid lubricant 2 is inlaid in the blind hole of bearing inner wall.
No matter be which kind of embodiment, can play equally and improve greasy property, increase the good characteristics of wear resistance.
