摘要： A plain bearing comprises a metal backing, a layer of a porous matrix of sintered metal on the backing and a filled PTFE infiltrated into the interstices of the sintered layer and standing proud of the sintered layer, wherein the PTFE is filled with 1-20% by volume fibrillated aramid fibres and 10-30% by volume glass. The glass is preferably E-glass present as milled filaments of length 0.05-0.30 mm and diameter 0.010-0.020 mm and coated with a silene sizing agent. The fibrillated aramid fibres provide reinforcement and improved load bearing capacity and the glass provides an abrasive filler which abrades asperities on a body and creates a smooth polished surface against which to bear, thereby improving its life. The PTFE preferably also includes ferric oxide and carbon black to about 1.5% and 1.2% by volume respectively which both pigment the polymer and act as an abrasive and lubricant respectively. The carbon black content may be increased to about 10% to provide electrical conductivity. The filler may be prepared as a wet mush or a dry “paper”.
摘要翻译： 滑动轴承包括金属背衬，背衬上的烧结金属多孔基体层和浸入烧结层的间隙中的填充PTFE并且被烧结层骄傲的PTFE，其中PTFE填充有1-20％ 体积的原纤维芳族聚酰胺纤维和10-30体积％的玻璃。 优选玻璃优选以长度为0.05-0.30mm和直径为0.010-0.020mm的经研磨的长丝存在并涂覆有硅胶施胶剂。 原纤化芳族聚酰胺纤维提供增强和改善的承载能力，并且玻璃提供磨料填料，其研磨身体上的粗糙度并产生平滑的抛光表面以抵抗该表面，从而改善其寿命。 PTFE优选还包括分别为约1.5％和1.2体积％的氧化亚铁和炭黑，其分别对聚合物着色并用作研磨剂和润滑剂。 炭黑含量可以增加到约10％以提供导电性。 填料可以制成湿糊状物或干燥的“纸”。

摘要： A dry bearing (102, FIG. 2(f)) for a hinge pin or the like comprises a bush 402 mounted in a radially supportive housing (16), the bush being formed by a circumferentially discontinuous tubular form made by rolling a strip of steel-backed, bearing material having a filled polymer infiltrated sintered bronze (ISB) lining about a mandrel (FIG. 32, 2(c)). The tubular form is, after mounting and to provide a more uniform inside diameter, burnished by pushing therethrough a burnishing tool (50), having a cylindrical portion (51), of larger diameter than the mounted form. The bearing (and method of manufacture) differ from the art in that a minor part of the lining surface is, prior to passage of the burnishing tool and conveniently when still in strip form, compressed in part as depressions (troughs 442) arrayed over the surface. Such depressions permit burnishing with a less oversize tool to get said uniform inside diameter, thereby requiring less work in driving the tool and with less risk of shearing the lining components and damaging the surrounding housing with radial pressure during burnishing.

摘要： A plain bearing comprises a metallic backing, a sintered porous metal layer bonded to the backing and a lining layer infiltrated into the pores of the porous metal layer and overlying the sintered metal layer, said lining layer comprising PTFE containing 10-30% by vol. of particulate wear-resistant filler, 2-10% by vol. fibrillated aramid fibers and 2-10% by vol. of a melt processable fluoropolymer. The melt processable fluoropolymer is a copolymer of the group tetrafluoroethylene-hexafluoropropylene, tetrafluoroethylene-perfluoroalkylvinylether and monofluoroalkoxy. Such a bearing exhibits superior cavitation erosion resistance and may, by increasing the temperature and/or duration of the sintering operation that is normally performed after the mixture of ingredients has been applied to a backing material, be made to exhibit significantly improved fatigue strength.
