Abstract
The invention discloses a rocker arm rod end joint bearing. The rocker arm rod end joint bearing comprises a rocker arm rod body, an outer ring and an inner ring. The outer ring is connected to the rocker arm rod body so that an assembly of the outer ring and the rocker arm rod body is formed. The inner ring is put into the assembly of the outer ring and the rocker arm rod body. The outer ring is prepared from a fiber-reinforced thermosetting composite material. The rocker arm rod body is made of high temperature-resistant stainless steel. The structure of the rocker arm rod end joint bearing realizes fixing and adjustment of angles of a compressor guide vanes at a high temperature. The rocker arm rod end joint bearing has a simple structure and is convenient for installation.
Description
Technical field
The present invention relates to a kind of rocking arm spherical plain bearing rod end, specifically, what relate to is a kind of rocking arm spherical plain bearing rod end that is used for airplane engine.
Background technique
Joint shaft bearing is widely used in fields such as automobile making, engineering machinery, aviation manufacturing, can bear bigger load and impact resistance, have anticorrosive, wear-resistant, from aligning, the lubricated good or unlubricated dirt pollution characteristics of selflubricating.Spherical plain bearing rod end is the joint shaft bearing that has rod end or be loaded on rod end, and it belongs to a type in the joint shaft bearing.
Like application number be: 200510060707.2 Chinese model utility, this model utility provide that " a kind of joint shaft bearing is made up of outer ring and inner ring, and the inboard of outer ring is the spill sphere, and the outside of inner ring is convex spherical, and two sphere radians are consistent.Convex spherical along inner ring is provided with two arc raceway grooves, on the arc raceway groove, is provided with some steel balls.The outer ring of bearing adopts 20CR steel for carburizing, inner ring and steel ball to adopt the GGR15 steel to make, and through quenching, tempering heat treatment.
The both sides of joint shaft bearing respectively are provided with a dust cover.……”
And for example, application number is: 200520136500.4 Chinese model utility, this model utility provide that " a kind of spherical plain bearing rod end is made up of rod end body, plain radial bearing.In the spherical plain bearing rod end outer cover seal closure is housed, uses the seal ring of band skeleton in inside, and radial bearing inner ring outer surface leaves blind hole, inlay solid self lubricant material in the blind hole.……”
But above-mentioned patent all can't be used for airplane engine, can't realize fixing and adjustment gas compressor guide vane angle function under the high temperature.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency of the prior art, a kind of rocking arm spherical plain bearing rod end is provided, this bearing can satisfy the usage requirement of fixing under the high temperature with gas compressor guide vane angular adjustment.
For realizing above-mentioned purpose, rocking arm spherical plain bearing rod end of the present invention comprises the rocking arm body of rod, outer ring and inner ring, and said outer ring connects the said rocking arm body of rod, forms an outer ring and body of rod assembly, said inner ring embedded outer ring and body of rod assembly.
Further, the said rocking arm body of rod, it is shaped as " Z " shape of inclination, and an end that is somebody's turn to do " Z " shape connects said outer ring.
Further, said outer ring is that fibre-reinforced same with thermosetting compound material is processed.
Further, the said rocking arm body of rod is that Vickers hardness is processed more than or equal to the high temperature resistant stainless steel of 300HV.
The present invention adopts after the technique scheme, and the structural type of rocking arm spherical plain bearing rod end has realized fixing and adjustment gas compressor guide vane angle function under the high temperature.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the plan view that removes the bearing inner race and the outer ring rear arm body of rod.
Embodiment
Below in conjunction with accompanying drawing and embodiment technological scheme of the present invention is done further to explain, but following content is not used in qualification protection scope of the present invention.
As shown in Figure 1, a kind of airplane engine is used the rocking arm spherical plain bearing rod end, has realized fixing and adjustment gas compressor guide vane angle function under its high temperature.This bearing comprises that the rocking arm body of rod 3, same with thermosetting compound material outer ring 1, inner ring 2 form, and said outer ring 1 connects the said rocking arm body of rod 3, forms an outer ring and body of rod assembly, said inner ring 2 pack into outer ring and body of rod assembly.The raceway of outer ring 1 is a concave-curve, and the raceway of inner ring 2 is the convex arc type, and concave arc is identical with the convex arc spherical diameter, thereby makes outer ring 1 be wrapped in inner ring 2 outsides.
The said rocking arm body of rod 3, it is shaped as " Z " shape of inclination, and an end that is somebody's turn to do " Z " shape connects said outer ring 1.
Said outer ring is fibre-reinforced same with thermosetting compound material, shows down more than or equal to 250 ℃ melting point and the tensile strength of 100 ~ 170MPa at 25 ℃, demonstrates the intensity of under 50 ~ 270N pressure, not deviating from 200 ℃.
The said rocking arm body of rod is a high temperature resistant stainless steel, and its Vickers hardness is not less than 300HV.
Embodiment 1:
In the present embodiment, said rocking arm spherical plain bearing rod end boundary dimension is: 2.4 * 9 * 4/3, and outer loop material is a composite material; Wherein the glass fibre enhancing is 25%, behind an amount of thermosetting plastics batch mixing 30min, is heated to 300 ℃; Through mold injection molding is the outer ring, and the raceway sphere diameter is 5.1mm.
In the present embodiment, the rocking arm body of rod is selected the GH4169 steel plate, and hardness is 368HV behind the solid solution aging, with the steel plate impact briquetting, obtains the body of rod through professional precision die, and behind surface finishing, the outer ring packed into becomes outer ring and body of rod assembly.
In the present embodiment, inner ring adopts the 9Cr18 stainless steel, and through solid-solution and aging heat treatment, Rockwell hardness is 52 ~ 64HRC, through the grinding machine correct grinding and roll grind after, pack into outer ring and body of rod assembly.
Present embodiment adopts after the above-mentioned preparation method and material, and the resulting rocking arm spherical plain bearing rod end life-span has reached the requirement with engine operation 4000h.
The present invention can be applied to airplane engine, has realized its at high temperature fixing and adjustment gas compressor guide vane angle function through this rocking arm spherical plain bearing rod end.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
