摘要： Upset oilfield tubing or upset pump rods are protected from abrasive wear by non-metallic circumferential wear bands applied to the upset portions of the tubing or rods and/or at selected locations along non-upset portions of the tubing or rods between the upset ends. The wear bands may be formed from selected polymeric materials including thermal polyurethane, polyphthalamide PTFE blends, and polyether ether ketone (PEEK), injection-molded onto suitably prepared circumferential surfaces of the tubing or rods. The wear bands may incorporate stainless steel mesh or other reinforcing materials embedded in the injection-molded polymeric material.

The intermediate layer is an arrangement of wires or a perforated plate. The arrangement of wires or the perforated plate forms undercuts and the plain-bearing layer is a layer made from polyether ether ketone.

摘要： A system for elastically compensating for wear, thermal expansion and misalignment comprises a ring located between a housing and a pin in the bore of the housing. The ring has a backing layer, an expanded grid structure having a plurality of openings, a low friction layer penetrated into the openings of the expanded grid structure, and adhesive for bonding the backing layer, expanded grid structure and low friction layer together to provide elastic deformation of the ring between the housing and pin.

摘要： A track-roller bearing assembly is disclosed which includes a fixed inner ball race member having an outwardly facing arcuate peripheral bearing surface; an annular body of self-lubricating bearing material affixed to the outwardly bearing surface of said inner race; and a coaxial outer race which is rotatable about an axis of the inner race and anguarly displaceable relative to the axis of the inner race so as to accommodate track deflections or irregularities. The track-roller further includes a resilient element disposed between respective ends of the inner and outer races so as to bias the races back into axial alignment after they have been angularly displaced relative to each other.

摘要： A spherical bearing comprises an outer ring and an inner ring located inside the outer ring to be slidable, the outer ring is prepared by casting molten metal around a resin-made sheet to be coated on the inner ring. A liner disposed between the inner and outer ring comprises a liner body and a metallic mesh member embedded in the liner body, and the molten metal is filled in meshes in the mesh member so as to partially bite the inner peripheral portion of the outer ring to achieve the firm engagement of the liner with the outer ring.
