It is featured as using copper alloy layer being coated on internal surface of outside lane or on external surface of inside lane and being set with porosity of 8-15% as self lubrication layer then packing oildag in pores at said copper alloy.
Description
Technical field:
The present invention relates to a kind of self-lubricating knuckle bearing and manufacture method thereof, bimetal self-lubricating oscillating bearing and manufacture method thereof that especially a kind of manufacturing process is simple, cost is low, be suitable for producing in enormous quantities.
Background technique:
Because Cuprum alloy has the high lubrication effect preferably that reaches of intensity, the working surface of therefore existing self-lubricating knuckle bearing is the Cuprum alloy face mostly, its structural type and manufacture method have following several basically: a kind of is to adopt casting method to cast out the whole joint shaft bearing outer ring or the inner ring of Cuprum alloy tubular that be, through machining inner ball surface or outer spherical surface, even cloth hole on sphere, solid lubricant is embedded in the hole, processes through mill again.Because of inner ring or outer ring integral body are Cuprum alloy, exist a large amount of non-ferrous metals of waste, technology is loaded down with trivial details, cost is high problem.Another kind be with the copper alloy powder spreading on steel plate, form bimetal plate by sintering, and through the repeatedly rolling and processing that eliminates stress, make the low composite board of porosity ratio, be reprocessed into bearing inner race, with the steel outer ring internal diameter interference assembling of joint shaft bearing, exist the product assembly reliability poor, easily produce shortcomings such as displacement and complex structure, technology are loaded down with trivial details, cost height when using.In addition, because sintering process to the restriction of steel plate material, needs to adopt the low low-carbon steel plate of mechanical strength as the bimetal substrate,, can't be complementary with bearing outer ring intensity to such an extent as to extrusion-deformation easily takes place under the working condition of heavy load.
Though existing plasma spraying technology or arc spraying technology all can be painted on copper alloy powder on the outer spherical surface of manufactured bearing outer ring inner ball surface or inner ring, two kinds of spraying methods exist following problem respectively:
1. plasma spraying method needs to adopt argon gas or nitrogen as shielding gas in spraying process, cost of production height, equipment investment are big, the high compactness Cuprum alloy coating that the spraying back is obtained, can not be as the self lubricating material of filling solid lubricant, can only adopt the oil lubrication mode, be not suitable for the production of self-lubricating knuckle bearing;
2. the formed copper alloy layer hole of electric arc spraying is big, intensity is low, thereon inlaid solid lubrication post and as the lubricated face of self-lubricating knuckle bearing, be not suitable for the production of self-lubricating knuckle bearing equally.
Summary of the invention:
The present invention is in order to solve existing in prior technology processing technology complexity, cost high-technology problem, provides that a kind of processing technology is simple, cost is low, reliability is high, the bimetal self-lubricating oscillating bearing of high lubricating effect and manufacture method thereof.
Technical solution of the present invention is: a kind of bimetal self-lubricating oscillating bearing, outer ring 1, inner ring 2 are arranged and place self-lubricating layer 3 between outer ring 1, the inner ring 2, described self-lubricating layer 3 is the copper alloy layers that are sprayed on outer ring 1 internal surface or the formed porosity ratio 8～15% of inner ring 2 outer surfaces with electric arc, is filled with aquadag in the hole.
The thickness of described copper alloy layer is 0.5～3.0mm.
Also can be on self-lubricating layer 3 even cloth hole 4, inlaid solid lubrication post 5 in the hole 4.
A kind of manufacture method of bimetal self-lubricating oscillating bearing is characterized in that having the following steps:
A. distinguish the outer ring 1 or the inner ring 2 of machining bearing;
B. 1 internal surface or inner ring 2 outer surfaces form the copper alloy layer of porosity ratio 8～15% in the outer ring with arc spray process;
C. the sandblast roughening treatment is carried out on the copper alloy layer surface;
D. in 8～15% hole, fill aquadag.
Described a step is that the electric arc spraying compressed air pressure is 0.5～0.8Mpa, and wire feed rate is 70～120mm/s.
Described d step is with rolled-on method or vacuum impregnation technology.
Described rolled-on method be with the aquadag brushing on the copper alloy layer surface, apply 0.1～0.2MPa pressure and roll, aquadag is filled in the hole.
Described vacuum impregnation technology is to be placed in the aquadag under the vacuum environment being coated with the outer ring of copper alloy layer or inner ring, and aquadag is filled in the hole.
Degree of vacuum in the described vacuum environment is that 0.3～6Pa ， Jin Plot time is 2～4 minutes.
The present invention adopts arc spraying technology, Cuprum alloy is overlayed on self oiling bearing outer ring inner ball surface or the inner ring outer spherical surface, the porosity ratio of controlling coating simultaneously is 8～15%, in hole, fill the aquadag oiling agent, promptly improved the intensity of copper alloy layer, make product have antifriction, selflubricating, non-maintaining, usability that reliability is high again, manufacturing process is simple simultaneously, cost is low, be suitable for producing in enormous quantities, has overcome the existing in prior technology problem.
Description of drawings:
Fig. 1,2 is the structural representation of the embodiment of the invention.
Embodiment:
Below in conjunction with Fig. 1,2 explanation the specific embodiment of the present invention.
Embodiment 1:
