Such as application number be: 200510060707.2 Chinese model utility, this model utility provide that " a kind of joint shaft bearing is comprised 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, is provided with some steel balls at the arc raceway groove.The outer ring of bearing adopts 20CR steel for carburizing, inner ring and steel ball to adopt the GGR15 steel making, 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 comprised of rod end body, plain radial bearing.In the spherical plain bearing rod end outer cover seal closure is housed, uses the seal ring with 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 under the high temperature and adjustment gas compressor guide vane angle function.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of rocking arm spherical plain bearing rod end is provided, and this bearing can satisfy the usage requirement of fixing under the high temperature and gas compressor guide vane angular adjustment.
For realizing above-mentioned purpose, rocking arm spherical plain bearing rod end described in the utility model comprises the rocking arm body of rod, outer ring and inner ring, and described outer ring connects the described rocking arm body of rod, forms an outer ring and body of rod assembly, described inner ring embedded outer ring and body of rod assembly.
