In above-mentioned spherical plain bearing rod end, described lubricating structure comprises the some oil storage micropores that are distributed on the lining.Can storage profit conversion materials.
In this spherical plain bearing rod end, when being in off working state, be filled with lubriation material in the oil storage micropore of lining; When in running order (comprising load condition), rolling ball rotates relative to lining, because frictional heating, the lubriation material in the oil storage micropore of lining is overflowed, and the lubriation material that overflows wraps up rolling ball; Reduced the friction of rolling ball to lining, high lubricating effect.
In above-mentioned spherical plain bearing rod end, the internal surface of described lining is provided with oil leab.Further strengthened the memory space of lubriation material, made lubrication effect better.
In above-mentioned spherical plain bearing rod end, described sleeve inner surface is the arc surfaced that adapts with the rolling ball outer surface.Be conducive to store lubriation material.
In above-mentioned spherical plain bearing rod end, described lining is made by copper based powder metallurgy material die casting.Certainly, mechanical property requires and material with oil storage function all can use as long as the material here can satisfy.
In above-mentioned spherical plain bearing rod end, the respectively concordant setting of the two ends of described rod end body two ends and lining two ends and rolling ball.
As another kind of scheme, in above-mentioned spherical plain bearing rod end, described rod end body two ends and the concordant setting in lining two ends, the two ends of rolling ball extend to outside the lining two ends.
In above-mentioned spherical plain bearing rod end, described through hole center line and eyelet central lines.Be difficult for occuring the lateral deviation phenomenon during assurance work.
In above-mentioned spherical plain bearing rod end, described rod end body and rolling ball are made by stainless steel.Structural strength is high, is difficult for getting rusty.
Compared with prior art, the advantage of this spherical plain bearing rod end is: 1, reasonable in design, simple in structure.2, when being in off working state, be filled with lubriation material in the oil storage micropore of lining; When in running order (comprising load condition), when rolling ball rotates relative to lining, because frictional heating, the lubriation material in the oil storage micropore of lining is overflowed, the lubriation material that overflows wraps up rolling ball; Reduced the friction of rolling ball to lining, high lubricating effect.3, structural strength is high, is difficult for getting rusty.4, long service life.
