    • A self-lubricating bearing is fabricated as a laminate of a metallic substrate and a series of raised structures formed integrally therewith and extending orthogonally therefrom. A fluoropolymer sliding or bearing layer is superposed with the substrate, with the raised structures embedded therein. The raised structures serve to hold the bearing layer in place to help prevent it from sliding along the surface of substrate during bearing operation. This anchorage to the substrate enables a relatively thick bearing layer to be utilized to relatively reduce tendency to creep. Alternatively, the structures provide a bearing having a relatively thin load bearing layer with a relatively constant friction coefficient over its life, with the structures acting as thermal and electrical bridges for relatively high heat and electrical conductivity between the substrate and a supported article such as a rotating shaft. The structures also may be in direct contact with the supported article to help prevent bedding-in. In this regard, the bearings are provided with a relatively low coefficient of friction, long bearing life, resistance to creep and mechanical stresses, and are electrically and thermally conductive.
    • 制造自润滑轴承作为金属基板和与其一体形成并与其正交延伸的一系列凸起结构的层叠体。 氟聚合物滑动或承载层与衬底重叠,凸起结构嵌入其中。 凸起结构用于将轴承层保持在适当位置,以帮助防止轴承层在轴承运行期间沿着基板的表面滑动。 这种对基板的锚固使得能够使用相对较厚的轴承层来相对减少蠕变的趋势。 或者,该结构提供了一种轴承,其具有在其寿命期间具有相对恒定的摩擦系数的相对薄的载荷承载层,结构用作热和电桥,用于在基底和支撑制品之间相对较高的热和电导率,例如 旋转轴。 结构也可以与所支撑的物品直接接触以帮助防止被褥。 在这方面,轴承具有相对较低的摩擦系数,较长的轴承寿命,抗蠕变性和机械应力,并且是导电和导热的。
